Anthropic, very interested in how this goes for you as I would like to find a way to keep mine cooler as well. My pond is just under 1 acre and the surface temps, as of right now, are running in the low 90's! It fact, it was 83 degrees two few down! Something you may want to look into is Craig's List. There is a continuous ad that I see around here where someone is selling vinyl billboard coverings for only $10 each. If you could get some mostly white or light colored ones, that would be a cheap way to try it out. Just a thought...
Good idea! I'll have to check it out.
My oldest fishing buddy is going to drop by next week so I'll have some help setting up some habitat, including tarp (I hope).
