I will need help with this. Others that were there please add comments. I can't remember the main details of Bob's talk. I forgot to take notes. Dah! I am going to email Bob to see if he will send me a copy of his talk.
On this same on/off aeration topic, Dr Amanda Quillen (Vertex) also presented "What Happens With On-Off Bottom Aeration. She had more scientific details on the topic. She basically tested the chemical changes that occur in the deep water when the aerator is shut off. As I recall she found in her specific study pond in FL that the DO dropped to low levels (2-4ppm) and anoxic chemicals increased after about 3-5 days with no aeration depending on conditions. I don't remember how deep her study pond was but I think it was 20+ft. Anyone remember the specific depth?
