Thanks guys! Mike, I changed my runtime to 11PM to 8AM so maybe that will help. I'll continue to monitor DO and see if that is enough to keep it aerated at depth. Even though my pond is 1 surface acre, the sides all slope in pretty good so my water volume is less than a standard 1 Ac pond. With three diffusers, I'm hoping I can get a pretty rapid turnover that will allow me to get by with the shorter runtimes. Thanks again!
