Cecil how do you keep your water quality in good shape feeding at such a high rate?
I think the diffusers help a lot and I'm sure the Chara and Sago Pondweed also take up ammonia from the water. Hence why I have so many weeds! I'm also using Aquashade in both ponds which should suppress an out of control algae bloom. And I only feed once per day.
In aquaculture the upper limit is supposed to be 30 lbs. per acre per day with aeration. That comes to 900 lbs. per acre per month!
