I am a little bit confused. If flood and drain grow beds are removed, where the nitrification process will take place? For this process to happen do we not need to have media?
Hi Baris, If you used DWC systems and have a correctly stocked system then the underside of the DWC floating polyethylene sheets along with the bottom and sides of the trough will provide sufficient surface area for nitrification. The University of Virgin Islands conducted research on this subject and shown that a properly sized DWC system will support nitrification for up to 3 times the recommended feeding rates. In this case you don't need additional bio filtration. You only need additional bio filtration if you're mixing systems i.e DWC and NFT together or if you're running an NFT alone or Towers that don't have media.
The School of Aquaponics can you use swimming pools as fish tanks or would they not work? Such as maybe a 1000 gal. Trying to design a system that I can use to grow leafy greens, tomatoes, cucumbers, and maybe corn to feed the family. And I would like to use tilapia too. Can you help me design a system that is capable of doing this?
What happens if the power goes off? Do you need a second battery powered pump to cut in in these circumstances, particularly at high fish stocking levels?
Just found your channel and I like what I see so far. I would question the idea of not using IBC tanks for fish. I know the standing theory is that IBCs won't get rid of solids well but I have to say that I have an IBC FT and there are no solids gathering in it. I will admit that the tank is grossly overstocked and that in itself might contribute to the lack of solids since there is so much movement to keep the solids stirred up and not settling before being removed. In any case in terms of saving money used IBCs (I paid $35 each for mine) will save a lot on initial investment for newcomers and can be replaced easily at a later date once the system has been proven and the hobby or commercial operation continues.
I like your channel after long time learning I thought I got it most of commercial Aquaponics knowledge but I got more to go I'm glad I found you. I'm planning to build commercial Aquaponics in Africa 3000 - 6000 sqft. I do have my blue print ready but are you willing to consult me? please let me know. Tnx
I still think he needs air stone or some type of aeration

Varun Narinesingh Usually best to have aerators in fish tanks and media tanks (plastic beads that hold bacteria). You can run each pair (fish and media) off the same pump with a split air line.
Great insight, the truth can set anyone free from headaches and mistakes
Great information here. You really do a great job breaking things down to easily understood concepts .

Great stuff.
what is wrong with using ibc totes?
Daniel Harder solid not going to be removed efficiently cause it square plus round tank better for fishes

Are you saying that the IBC totes in this system are going to be a problem with solids or is that IBC totes in general?
In general if you have moderate to high stocking densities.
IBC totes are good for small scale systems but in a bigger system with more bio-load stock numbers an aeration an solids become an issue
