I raise phyto for my tank. I feed my 180 gallon tank 1 cup every other day. It is the greatest stuff in the world for growing pods. I have a mandarin dragon that went from poor to fat as a tick by eating the hoard of pads that this stuff grows. Even with the mandarin, my tank is full of pods. It's great fun to watch them with a flashlight after the lights are out.
