Do I need to add any fertilizers or supplements?

If the system is balanced and you’re using a good quality fish feed, you don’t need to add any fertilizers or supplements.

This is a key advantage of iAVs, as it reduces reliance on external inputs and makes the system more sustainable and cost-effective. The solid fish ‘waste’ contains a large portion of the nutrients. Most traditional aquaponic systems do not utilize all of the ‘waste’ generated by fish and so they remove the nutrients from the system and need to use additional supplements. In iAVs, the fish ‘waste’ is fully utilized thereby making use of the nutrients which are normally discarded.
