Joey, as trialsguy said, definitely consider AC power to the pond; or an airline. You can never get near the bang for the buck with solar. It is just an alternative for very remote sites. The small compressor like myself, trial, and some others work well enough for 1/4 or 1/2 acre ponds up to 10 ft. deep. You said you have 1 acre and want to aerate 1/2 of it that is 6 ft deep. Tell us about the rest of the pond. Is it deeper, shallower, is it shallow with a deeper hole or 2? C & S sales may have more of the surplus units that draw 1/2 amp. Just dont want you to be disappointed. Tell us more.
