Oh, I see ~ three readings from 6PM and 2 from 6AM ~ definitely inadequate aeration. Warmer water temperatures do hold less water, but if properly sized, a bottom diffused aeration system would show higher DO levels. At 95 degrees, water can hold 6.95 PPM dissolved oxygen. I still recommend talking to Ted ~ if you want to stick with a "do it yourself" system, he'll be able to help you out. Highflyer actually shot some video of him this weekend at our Pond Boss gathering in Indiana about this exact subject. Hopefully it will be posted soon.
