QA, I hope you don't mind me jumping in here but your post about whether to aerate or not along with Bob Lusk comments about water temps verses DO has me questioning where to go with my existing aeration system. Do I want cooler water or higher DO numbers. I have been searching for a leak in my 1800' of air line along with rebuilding two pumps has kept my aeration shut down so far this year. I'm still working on solving the problem of not enough air to run the six diffuser system. After 4 yrs of aeration experience at my pond, I continue to questioning myself on how to keep my water temps down and DO up during our hot summers temps? Even after I fix my aeration system, I may just leave it off this summer just to see what I can see. My fish seem to have survived my 92 to 87 degree water temps over the past summers using aeration with no thermocline. How will they do without aeration but cooler water temps may be answered this summer.
