Hi, I'm currently in Uganda trying to build an aquaponic system for an NGO...they already have 3 fairly large tilapia ponds, so I'm thinking of using the smallest one (100,800 L) for aquaponics. Can someone share some tips on the differences between pond and tank aquaponics? I've only done aquaponics with tanks before. Specifically:
1) Do I still have to circulate the volume of the FT (or pond in this case) every hour? That seems excessive.
2) Can I size a RFF the same way as in tank aquaponics?
3) How can the fish in the pond receive adequate aeration? Do I need airstones and an air pump? The area doesn't have electricity, so we're trying to keep the power requirements minimal and use solar.
