I've been doing some reading on the benefits of surface vs bottom aeration. It seems most of the experts tend to lean toward bottom aeration in ponds with depths of 8 feet or better, and surface aeration for shallower ponds.
That's got me wondering if three diffusers may be way more circulation than you need with an average depth of 6-7 feet, even with an acre of surface. You may want to try to cut back on how much air is getting to each diffuser, or even shutting one down completely (in the deepest part) to allow that section of the pond to cool more and create a refuge for your fish.
It's just a thought and I may be way off base. Maybe someone with more experience will step in and enlighten us both.
