Even with three days of cloud cover, nighttime temps in the 70s and rain, the pond is still hanging around 80 on top. With the installation of my DIY fountain in place, I've decided to turn my bottom aeration off for the summer and try using surface aeration only. It has done an amazing job of controlling PA blooms so far and I hope the to be able to maintain some decent DO as well as cooler temps in the mid depths. As soon as daytime temps reach the mid 80s again, and stay there or cooler, I'll be switching back to the diffuser and let it run 24/7.
