The best aquaponics secrets finally revealed

This is the video were I announced that I will now offer aquaponics advice and give my best tips away :)

How to keep your fish tank clean in Aquaponics!

In this video I show you how to avoid organic matters and mud to accumulate in the bottom of the fish tank using a simple tool. This easy task will avoid a lots of problem including fish disease that can appear when the fish tank hygiene is not respected.

How to feed your fish in Aquaponics?

Feeding your fish seems to be a basic task but is actually more complicated than it seem. following the techniques detailed in this video will allow you to grow healthy fish, maximize the growth and minimize the size variation between the fish.

Question from Garry:

Is there any effect on the fish being in captivity? In Tassie they have to feed a chemical to the fish to make it pink as it goes grey. Regards Garry


Dear Garry,

Thanks for your question.

Trout/Salmon flesh colour depends on the kind of food they will find. In the natural environment they feed on different animals and sometimes crustaceans such as “gammarus” that contains natural carotenoids responsible for the pink colour. If they don’t find those crustaceans, the colour of their flesh will be white. In aquaculture, artificial colorants such as astaxanthin are added to the food in order to colour the fish flesh up to the customer expectations.

Please note that in some countries such as Switzerland and Germany the consumer is not used to eat pink salmon/trout and therefore the fishfarmers don’t use any colorant and supply a fish with white flesh.

In Aquaponics I would suggest to avoid the colorants in the fishfood you buy as they are useless for the fish.

I hope it responds to your question.

Kind regards,


The Aquaponics DNA principle

In this video I give you an overview of the Aquaponics philosophy. The idea is to produce food with nature, using the life cycle. 

Grow crustaceans in Aquaponics

This series of 2 video will help you to introduce crustaceans in your aquaponics setup. They can very often be mixed with the fish without problem and will clean the bottom of the tank eating the left over of food.

The Golden rule to start your Aquaponics setup

Cycling a system is a critical process, it often lead to success if well managed but can lead to disaster if not done properly. Make sure to check this video if you want to go ahead with Aquaponics 

Question from DQuincey Hjornevik:

OK, I get to not add the fish right away. No fish no ammonia so you add fish food. What amounts of fish food or ammonia for what size systems? No bacteria no Nitrites and so no Nitrates. Thanks for warning about these issues. More please.


Thanks DQuincey, that is a very interesting question. The general advice is to add a handful of fish food but you are raising a good point here. This quantity of fish food is linked to the quantity of bacteria we will have to develop so I will do my best to give you a bit of technical information:

The quantity of fish food to distribute in your fish tank will be dependent on the temperature (summer, winter), the volume of your growbed and the quality of your media. All those values will have a huge impact on the general biomass of bacteria able to be developed in your system as well as their growth rate and their nitrogen needs. Because we are cycling the system without fish we don’t really mind to give too much food to our bacteria, it will obviously create a large peak of ammonia and later nitrite in our setup but it will slowly decrease as the biomass of bacteria will grow. If you put way too much fish food than needed the bacteria will take a bit longer to transform the whole Ammonia and Nitrite and therefore after a month of cycling you could still have some toxic nitrogen in your water.

I see 2 ways to approach this exercise:

The first option is to develop the maximum biomass of bacteria that the system can handle. Example you have a 1000 litres setup with a growbed of 250 litres filled with very efficient media (small size Scoria/clay balls/other very porous media). As a rule of thumb I know that this kind of media can accept up to 20g of food per 50 litres of media per day (variable depending on temperature) so the whole system could take up to 100g of fish food per day. We know that the bacteria biomass growth is exponential (certain populations of bacteria can double every 20 minutes) so the first days of cycling the bacteria biomass will be extremely low and in the last days the population will be at the maximum. To develop the maximum bacteria population we can simply distribute the equivalent of 5 days of fish food so 500g.

From my perspective this option is not the best as it develops the maximum population of bacteria that the system can handle but it’s never useful as we generally start from fingerlings fish (very small fish). In result it waste too much fish food and if the estimation here is slightly wrong or if the water temperature is too low, the nitrite will take a lot of time to come back to 0 and the cycling process will take more time than necessary.

The second option is to have for aim to develop at least the quantity of bacteria necessary to handle the biomass of fish that you will introduce in your setup just after cycling. The rule to follow is to distribute the equivalent quantity of 5 days of fish feeding in your system. For that imagine the biomass of fish you will have when starting your setup. Let’s take the example a 1000 litres setup that starts with 50 fingerlings of 3g each. The total fish biomass will be 150g. Let’s imagine its summer, the feeding ratio will be around 6% so the total feeding needs will be 9g per day. In 5 days you will approximately need 45g of fish food.

You see here that using those 2 methods, any quantity of fish food between 45g to 500g will correctly do the job. Note that in the worst case scenario if you put too much fish food you will have to wait a bit longer for your toxic parameters to come back to normal, if you put too little quantity of fish food you may experience very little peak of ammonia and nitrite when you introduce your fish but it will probably not be significant as the bacteria population will very quickly adapt to your new fingerlings population. The bottom line is that I personally think that a little handful of fish food will easily do the job for most backyard aquaponics size setup and I don’t think very necessary to bother people with those painful calculations based on estimations anyway. 

Maximize your fish production in aquaponics!

There are a few points to be aware if you want to optimize your fish production. It is always better to grow several small fish than a few big ones as the total biomass growth will be much higher. In this video I will also reveal how the large majority of the trouts are produced, it will probably blow your mind!

How to safely cycle your aquaponics setup

In this video we will what are the main points of cycling a system

Select the right media for your aquaponics setup

Too many Aquaponics growers are using an inefficient media and are therefore very limited in terms of production. In this video I will show you how to select an adapted media that is both very efficient and doesn’t react with the water pH!

Use the right water for your Aquaponics system

The water we are using in our aquaponics setup will stay in the system for a while and can impact the bacteria, the fish and the vegetables so we need to make sure that it is adapted. In this video I will give you some good tips in order to select and use the perfect water for your system.

Select the good water pump for your Aquaponics setup

In this video I will explain you how to select the best pump for your setup. Always keep in mind that the smaller the water pump and the more sustainable your setup will be.

The key point to manage fish disease in Aquaponics

Fish disease can be challenging but if you respect some basic points detailed in this video you will avoid most of them. Always keep in mind that the key is to offer a good environment to your fish and avoid to stress them to avoid the problems.

The number one factor to manage pest and predator on your vegetables in aquaponics

As you know, in all gardens we find bugs that are eating the crop. In classic agriculture the farmers are using pesticides to kill the pest and by doing so they kill the majority of living creatures. In aquaponics we will not follow this principle for 2 reasons:

  • First we can’t use pesticides in our growbeds as the chemicals would contaminate the fish and probably kill the bacteria.
  • Secondly in a monoculture (classic agriculture) there is no biodiversity and once a pest is present it spreads very rapidly on the whole crop. The aim of aquaponics is to produce in a sustainable way and to use the natural cycles. In nature all populations are balanced, each population is regulated by a predator. This is this specific particularity that we use. Working with a variety of vegetable species allow a wide biodiversity of insects and therefore each pest has got a predator present into the ecosystem. Biodiversity is the key to preserve your crop from predators and I highly recommend to have a multitude of vegetable species in your growbed.

Minimize fish stress impact in Aquaponics

A very good trick to keep your fish calm and avoid problems in aquaponics

Tricks to protect your crop in aquaponics

2 easy tricks in order to protect tomatoes and other red fruits in your aquaponics garden. I can’t promess you that it will work everywhere but it worth the try!

3 facts about the bell siphon (in aquaponics)

The Bell siphon is a key component of the aquaponics system. In this video we will see:
1: The purpose of a bell siphon,
2: What it is composed of
3: How it works
A well designed growbed aquaponics system equipped with an efficient bell siphon request a very small water pump and is therefore very sustainable.

Acclimate fish in Aquaponics
Trick to acclimate and release fish in Aquaponics Introducing new fish into your aquaponics setup is a critical step. Before releasing the new fish into the fish tank it’s important to make sure that the temperature of the water into the transport container (often a plastic bag) and into the fish tank are the same. In order to adjust those water temperatures you can simply let the plastic container floating in the fish tank. The thermique balance will be reach after several minutes. Also make sure to not stress the fish too much. In this video I also share another interesting tip to allow the fish to fill even better in their new home. Please don’t hesitate to leave us your comments and to share the video with your friends.


Hi guys it’s Jonathan from Melbourne Aquaponics! just a quick video tonight because I just come back from the hatchery, I took some fish with me, some Silverperch and I was releasing them into my tank and I was just thinking that I wanted to show you how to deal with the fish during winter especially in Australia or in places where you got cold water because when the temperature is extreme, it can also be in warm countries, when the temperature is very high but when you are at the extreme and the fish are a bit stressed either because the water is too cold, they don’t have energy or either because the water is too high in terms of temperature and therefore as the oxygen concentration available into the tank is very low there is not… I mean there is not lot of defences, the fish have not many defences to fight against the disease and therefore there are lots of fungus that can develop into the water so here you can see I’m just back with some silver perch that are ready to be released into my tank you can’t see much but anyway there are a few fish around when you receive your fish what you want is to avoid to stress them and to acclimate them so what I do I just leave the bag into the water for few minutes, when I say a few minutes it is at least 15 minutes. I want the two temperatures, the water temperature into the bag and the water temperature into the fish tank to be the same. So the other thing that is important when the winter temperature is extreme like right now is to put some salt into the water right because it’s going to decrease the osmosis power of the water. So the water is trying to go inside the fish because the salt concentration inside the fish is way higher than into the water and therefore by putting a bit of salt into the water into the tank it kind of decrease the difference of concentration of salt inside the fish and into the water and it decrease this osmosis power so the fish has to spend less energy to fight again the osmosis so that’s really a good trick. The other really interesting point of putting some salt into the water is that the fungus don’t like it at all so if you got some fish that are very… I mean that have got some chances to get the fungus (Disease) or if you see the fungus on your fish put some salt into your water so the quantity of salt that I use is 3 grams per liter of water so for example if you go 1000 meter set up, you can put 3 kilo of salt. So the salt I use is a classic swimming pull salt so you want to make sure that there are no additive into the into the salt it’s just pure salt we don’t have any any bleach or any other kind of chemicals it’s just normal salt so here is the bag of salt that I use, I don’t want to make any ad, any free publicity for the brand, you can take any brand but basically it’s a swimming pool salt and you see a bag like this is 25 kilos and it costs $10 so it’s a very cheap thing so don’t spend your money into buying an expensive salt swimming put salt works extremely well don’t go over 3 grams per liter otherwise your vegetables are going to have some troubles to deal with the salt so you want enough salt to keep your fungus away but not enough to put your vegetables in trouble. So depending of the vegetable you have, some of them are able to handle the salt but the most sensitive such as the strawberries, after 5 grams per liter they start to show some signs, you can see that they don’t feel the best. Stay at three grams per liter, it’s enough to keep the fungus away or to decrease the activity and it’s completely acceptable for the vegetables. Guys I hope you enjoyed the video so this is just one trick. I got many tricks for you and I put all of them into the digital Aquaponics Manual. You can download a free version of this manual in the link here. Obviously this is just a very short version so you got only 40 pages the real version is hundred fifty-five pages but it’s going to give you a lot of tricks for free. So please download it. See you In the next video, I hope you enjoyed this one, bye bye!

The main advantages of AQUAPONICS

I am sure you have heard about aquaponics, it’s a fantastic way of producing fish and healthy vegetables in a sustainable and ecofriendly way but do you know what are the main advantages of Aquaponics? They are actually numerous advantages to grow food in aquaponics and I will not have time to go through all of them in this video but the main ones are developed here. If I forgot one of them please let me know in the comments.
Please don’t hesitate to leave us your comments and to share the video with your friends.

so the advantages of aquaponics are multiple right!? First obviously, you grow two crops, you don’t grow only one crop so… you’re going to grow vegetables plus fish the food that reproduce is extremely tasty because the food is growing in an ecosystem it has got all the nutrient it needs so they grow twice as fast on the normal garden there is no labour you don’t have to return the soil because you will find out later on that in an aquaponics setup we give the best conditions for the food but also for the bacteria that are into the system to work and therefore it’s always aerobic so you don’t have to work you know as in normal garden when you need to return the earth. You don’t need to do that here because there is always enough oxygen for the bacteria. Obviously we don’t use any chemical or any pesticides it’s all natural only good for you and the food is full of nutrients and vitamins because we work in a closed environment in a closed cycle we don’t waste any water we use ten times less water than a normal garden. The only water that we really use is when we got a bit of evaporation and we need to top up the tank. So because aquaponics is using the natural cycles it works with nature and not against nature therefore you don’t have to do anything you just live nature doing the job and there is no weeding because our systems are always waste bags so there are very few seeds that can fall into your bed so you don’t need to spend any time removing the bad weeds. Aquaponics is adapted to very small surface area so you can grow aquaponics in your own backyard or you just need a very small Terrace or even if you go a balcony you don’t need a big surface so really, if you got one square meter you can put an aquaponics setup in place aquaponics can bring nature back into the city and it reconnects people with nature. Aquaponics is also a real feature into your garden. Having aquaponics allows people to see a lot of insects animals fish. It can also be a bench such as if you see that’s a real bench you can sit on it, you got the fish underneath and you got the plants at the back it’s really a feature and a lot of people are interested into it when you got people coming around the kids are always around it and love it so it’s really… You produce food but it brings way more than just a production. It’s also a real feature into your garden

A Costly Mistake to Avoid in Aquaponics

All aquaponics growers will at one stage loose one or few fish. It can be due to different causes, linked to a mistake (poor water quality…), a disease or simply to the fish genetic. It’s always a sad moment but we must accept it, it’s part of nature, all fingerlings will not reach the adult stage and a success of 80% can be considered as very good depending on the species. When this happens you may be tempted to bury the dead fish into the growbed of the setup. It would make sense to leave the body breakdown and release the nitrogen and minerals back to the system. Unfortunately this is a risky option. If the fish died because of poor environmental conditions such as high ammonia or nitrite level, the fact to bury the dead fish into the growbed will make the situation far worst and could lead to a huge ammonia peak that could kill all your fish. Also if the fish died of disease/parasites, burying the dead fish will spread the disease and worsen the situation. In fine, when a fish die the best thing to do is probably to remove it as soon as possible and to give it to your chicken or to naturally recycle it in your compost.

A Costly Mistake to Avoid in Aquaponics content:

Hello sustainable growers! This is Jonathan from Melbourne Aquaponics! In this video I would like to talk about a potential mistake that could cost the life of all your fish. So I’m actually just back from holidays, I went two weeks in Europe and during those two weeks I had no one here taking care of my aquaponics setup so what I normally do I just leave the setups as they are, you know the fish can live for several weeks without food it’s not a problem, that’s something they do in the natural environment, and specially here it’s winter now so in winter you know the fish are not very active and they don’t need so much food but a friend of mine offered to come and to take care of the fish and to distribute a bit of food so I say okay, I was happy you know and I thought it was very nice so I just showed him to put a little bit of food but I explained him that it was important to not put too much food into the fish tanks obviously especially here I stock also sometimes some fish for my customers so my tanks are are quite high in terms of fish biomass so the system, the systems are close to the limit so by close to the limit I mean that I got just enough bacteria to cover all the needs or to absorb all the ammonia that comes from the fish so if I over feed the fish I may have some troubles and what happened is that when I came back from holidays my friend told me that he lost a few fish and he buried them into the growbed so it could seem like a good idea you know to keep the fish inside the system the fish died ok that’s lot of organic matter why don’t we use it into the system to use as a fertilizer for the plants you know to increase basically the nitrate that we’re going to produce into the system the issue with this kind of thing is that because I’m very close to the limits if I got a few fish that died for some reason it may be because you ever feed them and we were high in ammonia so if it’s the case, if you keep the dead fish and you put them into the grow bed you’re going to add even more nitrogen into the system and even more ammonia and if the bacteria biomass is already borderline in terms of capacity of ammonia absorption you may have a pic of ammonia and and then a pic of nitrite which could be obviously a big problem and could kill all the fish so it’s definitely not something to do. Obviously my friend didn’t know you know he doesn’t know anything about aquaponics he just wanted to help me and, I mean it’s super nice from him and I’m very happy that he helped me but just, I just don’t want anyone of you to make this kind of mistake if you have some fish who died where if you know that you are very far from the limit of your system and if you want to put them into the growbed it can be a good idea because obviously it increases the quantity of nitrogen that is into the system so it’s a bit more fertilizer for your plant. So if you are a bit low in terms of quantity of fish yeah that’s something you can do but if if you are like me if you are already crowded in terms of fish biomass if you got one or two fish that are dying, don’t bury them into the growbed just put them in your compost give them to your chicken do something different recycle them but don’t recycle them into the aquaponic setup. So here I’ve been very lucky because it didn’t have any real negative impact it didn’t kill the fish it didn’t create a pic of ammonia at least not not a pic of ammonia that killed the other fish and my friend just buried them into the growbed so what I’m very interesting to see now is to see where or to try to find the place where you buried them because I got a lot of worms and lot of animals insects in into the grow beds that are living and I would like to see if I find the body of the fish I’m sure they already decomposed and I would like to see if I find a big quantity of worms in one place I’m sure I’m going to find the place with lot of worms so let’s have a look right now I’m just going to grab a shovel to dig into the crowbed. So he told me that he buried them into this growbed so oh yeah here I’ve got some worms oh yeah look at that that’s the pine bone of the fish and on the pine bone I see a lot of little worms very small one whitish ones let’s see if we can find more oh yeah here’s a bone okay so apparently it was only two little fingerlings so it didn’t have a big impact on the rest of the tank obviously if you got lots of fish and if the big die just don’t worry them into the crew bed right and even if it’s just a few small ones you don’t know why is it died so if it’s because of a special disease by burying the fish the sick fish or the dead fish into the grow bed you’re gonna keep the disease right and it can multiply if it’s bacteria if it’s parasite you never know they may spread and may go back into the fish tank it may increase the disease so if you’ve got dead fish the best thing to do is basically to keep them away from the fish tank to give them to your chicken to put them in the compost or to recycle in anywhere but it’s not really into the grow bed of you aquaponic setup I hope you enjoyed the video I hope you learned something and I hope it’s going to avoid you a mistake that can that could have cost the life of your fish see you in the next video don’t forget that we got some webinars going on so you can subscribe to the webinars in the link here in this webinar I’m going to give you more information about aquaponics and few little tricks so it’s always interesting to be part of this webinar and I hope I am gonna see a lot of you in the webinar. bye-bye!  

Natural pest control Aquaponics

Natural pest control Aquaponics content:

Hello sustainable growers this is Jonathan from Melbourne aquaponics! In this video I would like to show you a little trick to manage the pests in aquaponics. As we know in aquaponics we don’t use any pesticide or any chemical to get rid of the pests and therefore we rely on nature and on the different interactions that we can have between different living creatures that are into the ecosystem, the aquaponics ecosystem. At the moments in Melbourne in Australia this is the end of winter and therefore the aphids are starting to grow and to colonize our crop. Unfortunately the Predators are not very present yet obviously they are coming but it’s still very cold and they always take a bit of time to arrive so we always got peak of pests, a peak of aphids and later on we got the Predators that are coming and it may take few weeks actually so during this time the aphids are very happy and they are going very fast so obviously I lose a bit of my crop which is okay it’s part of the of the of aquaponics and of working with nature but because we don’t have the Predators yet I’m going to use… I’m going to put the plant in contact with other predators which are actually the fish so I’m going to take few plans that are extremely affected by the aphids and I’m going to put them into the fish tank for a nice clean and that’s what we’re going to do right now okay so here we got broccoli but you can see that there are aphids everywhere so the problem with this kind of plant is that the aphids are on the leaves obviously. You see, it’s dramatic it’s on the leaves but it’s also on the seeds I mean when I said seed it’s actually not the seed it’s the flowers right just before the flowers but the problem is that the aphids that are here on the Base are going to be very hard for the… the fish are going to have some trouble to have access to those aphids but anyway I’m sure they’re going to find a lot of food below the leaves because you see there are aphids… oh look at this that’s horrible anyway its nature it’s okay it’s going to be a nice food for the fish so I’m going to take this plant out and I’m going to put it into the grow bed, I mean not into the grow bed sorry into the fish tank. What is very important and interesting to realize is that you see that I got aphids here on this broccoli I don’t have aphids on those little lettuce you see, and here I got another little lettuce, I got celery that is in perfect conditions you see so that’s the tricky in aquaponics and in permaculture it’s always to balance you know, if you put one species of vegetable if I had broccoli everywhere I would have had the aphids everywhere and I would lose all the crop. Here I only lose this plant and a few others that where around, few other broccoli but I don’t lose everything you see and a bit further here I got some other broccoli that are going very well. I don’t have any aphids on them, you see the leaves are perfect you can look underneath, it’s very clean. So that’s the trick of aquaponics it’s to… you know to put some barriers, the barriers are the other plants and therefore even if I lose a few here I can still up some broccoli here but also I got all my other crops that is in perfect conditions you see that this broccoli went into flowers because I didn’t pick it on time I was on holiday, I was away. But you see that everything is going really well I just have a little program on this one and I had another problem on the one below at the back, this one you see here. Unfortunately I get rid of all the aphids that were on it because I put it into the fish tank but the fish took it they ate all the leaves as well so this plant is not going well at all I don’t even know why I put it back and just want to see if it comes back if I can have something but anyway I’m not going to eat much from this broccoli anyway I already had a crop from it I already cut it here but I had some nice new seeds here and I was ready to pick it but unfortunately when I came back from holiday it was full of aphids so now the fish took care of the problem let’s see if it comes back and for this one I’m going to put it into the fish tank and I’m going to take care of it I’m not going to leave it for too long but unfortunately when I see where the aphids are I’m quite sure that the fish are not going to be able to remove everything because here you see they get rid of the problem but they ate everything right, so basically if I have to wait for this time they going to eat the leaves in the same time so basically the solution would be to put them only with fingerlings a silver perch are not eating the leaves at all so in this case it would be fine but here I mixed a mixer size in my tank I got both I got both fingerlings with big silver perch so there is no real option for me to just separate them so obviously while the small silver perch are going to clean and remove all the aphids, the big ones will focus on the leaves and then are going to start to eat the leaves so it’s going to be the challenge let’s see how it goes so I just put the plant into the fish tank upside down and you can see that the leaves are all deep into the tank and the fish have completely access to the leaves so they have also access to the aphids that are living all that are living on the leaves and here you can see that they are very attracted and they are all looking for those little aphids around so in this tank we have silver perch fingerlings but we also have biggest silver perch and the biggest ones are very attracted by the… by the plant itself they turn vegetarian when they… when they grow and they are trying to get a bite from the leaves so here I got a little challenge, I have to find the good timing, just enough time for the little fingerlings to eat all the aphids, but not enough time for the big silver perch to be confident enough and to come in to eat the leaves so I think I’m going to leave it for maybe 40 minutes and after 30 minutes I’m going to check and see how clean is the plant and see if we still have some leaves remaining. Okay so it has been now into the water for maybe thirty minutes, a little while so I’m going to stop even if we still have a few aphids I think so because I see that the fish are still on. I prefer to remove the plant now otherwise the big silver perch are really going to eat all the leaves and I’m going to lose the plant so we’ll see what… we’ll see how it is now so you can see that it was full of aphids everywhere and very honestly I can’t see any of the aphid remaining I can’t see any of them which is really good. I’m sure we still have a few here between those… those little flowers I’m sure they’re some but from a general point of view I think we remove most of them. Oh yeah here but I’m sure that’s a leaf… oh yeah here we still have one they, missed all those ones. Otherwise you can see that they definitely took care of the problem and I could definitely put the plant back into the water and but I’m just scared that they would… they would eat the flowers and the seed and their leaves so I’m just going to put it back, plant it back and see how it goes. I mean I’m going to remove the… the aphids that are still on the leaf that we can see with my fingers and put them into the fish tank later on so now I’m going to plant the broccoli back into the grow bed. Here we are… so now I’m just going to remove the… the leaves that were very much affected and that had some aphids remaining, I can’t find it anymore but maybe one of the big ones. oh yeah it’s yeah that one I got it so here you can see that I still have some aphids so what I’m going to do with this leaf I’m going to put it into the fish tank and the fish are going to have a feast and yeah we’ll see how this one goes or I’m sure that the aphids are going to come back anyway because I still that we still have a few between the flowers but anyway we took care of the problem here, we decreased the population. So this plant is still very weak but I hope that some predators are going to come and take care of the problem and by keeping this plant here the few aphids are going to still develop on this plant and it’s going to avoid to affect the older ones that are gone that are in perfect health. You can see that this technique is working quite well depending of the kind of fish you have obviously you need to have fish that are adapted to this kind of pest. If you’ve got very large fish they are never going to eat small aphids and if you got vegetarian fish such as I do, I got silver perch, if they are small like mine that’s okay, if they are big I got a few big ones into the tanks they are vegetarian so if it’s a soft plant such as lettuce you can’t do that because as soon as you put the lettuce into the tank, obviously the silver perch are going to get rid of the aphids but they are also going to get rid of the lettuce, of the of the salad right, of the whole plant. So you can’t do that with this kind of plant. If it’s cabbage you know those kind of leaves that are a bit stronger you can do it but just keep an eye on them because after a while they eat it anyway. I did… I made the mistake with the previous plant and… Well the plant lost all the leaves, obviously I don’t have aphids anymore but a plant without leaves is not the best. Anyway it’s mostly for fun because those plants that I’m putting into the tanks are very much affected by the aphids and even now removing the aphids is a bit too late. I’m just back from holiday so I couldn’t do it before but yeah normally we should do that a bit earlier. so anyway it’s still a funny thing to do because you get rid of the pests and it feed you fish the fish really love to have this kind of live food you know, it’s the best food you can give to your fish you know this kind of live insects it’s full of vitamins full of proteins as well and it’s completely natural and it’s really into the… you know the mindset that you should have in aquaponics and in permaculture to work with nature and to use a waste or a pest or something that is a problem and to use it as a something that has value for the system you know like here it’s the food of the of the fish at the end. So you know the food of the fish is very costly.
