Has anyone ever used vermicompost tea with aquaponics? I have found little formal research on the area and am curious if the two nitrogen cycles can be combined.
I don't know if I would mix the tea with the aquaculture, maybe feed the fish worms instead?
I think that by adding the nitrogen from the tea, you would just be adding more nitrogen to a system with it's own nitrogen input (fish poo), possibly more than the plants could take up, which could lead to algal blooms, and de-oxygenation, which might kill your fish.
Both are good systems, and perhaps could work together, the vermiculture taking inputs from roots and unused garden bits from the aquaculture, and the fish getting a wormy treat from time to time. Doubling the nitrogen at one point in one cycle makes less sense to me than combining the inputs and outputs of both systems.
I've not practiced either of these systems, so I'm just speculating.
