Hello all,
New member here, in midlands SC. Just bought a tract/home, with a potentially beautiful 1 acre deep pond. Fed by a couple of slow creeks, and there must be another spring source, as it stays full even in dry weather. Depth is more than my 16' tape measure, so not real sure, but lots of volume. PO were serious gardeners, so I suspect there may be some type of impact from 30 years of fertilizing everything up the hillside? There are confirmed very nice bluegill, some bass have been spotted, and plenty of sliders and mud turtles. Just bought the place, and want to go ahead and do everything I can to bring up the health of the pond. I am beginning to see patches (about a square foot) of a limey green algae, and it concerns me.
I have not tested, but I assume I have low DO. Clearly need to test. The banks of the pond have been let go for some years, so very grown up. I suspect plenty of muck on the bottom.

I have 240V at the pond, but only on demand from a sprinkler system 200 yards away at the house. LT plan would be to convert to a sub-panel and purchase a 240V aeration system, but I am trying to figure the ups and downs of current easy options.
Terrain is very rugged, and time is very limited, so getting a permanent system in now will be a challenge. Suppose I could just remove pond pump and swap for aeration system, since not irrigating from the pond right now? Use the sprinkler control box to cycle the aerator. I am reading to start very slowly; maybe 15 minutes per day? PO (deceased) left me an old garden hose under every pile of leaves in the woods; most are OK. Is there any benefit to using garage compressor and running air to the pond via about 10 garden hoses, through some type of diffuser? Could be an easy setup if it can work.

My objective is primarily to clean up, and clear up the pond, and ensure a healthy environment for bluegill, bass, and some catfish.

All feedback is greatly appreciated.
