We have a big sort of pond which is aerated by a largish aquarium pump (air pump only). We have carp and two turtles in the pond. My guess is the capacity is in the 1000 to 1500 gallon range.
I was wondering about the possibility of incorporating aquaponics into the structure as it currently exists. Ideas included adding styrofoam deep water floats with some light plants on them or trying to grow aquatic plants for food (lotus being a possible example). Given that the water does maintain ample aeration, what sorts of problems am I likely to face?
