The compressor I have is farly loud but I have 150 feet of hose so I put it in the back garage. I live in somewhat of a rural area so neighbors arent a problem. I have a 15 gallon coleman compressor it would run about one minute on 3 minutes off.

I waded around in the pool with it pulling it by the hose just off the bottom and it stayed on the bottom and didnt float when I left it in one spot.

I thought of making a atomizer for the end which would be just a empty bleach bottle filled with tiny holes and something to hold it down if needed. I have an AG pool 27 footer so I dont want bricks of metal harming the liner. In total it ran for about six hours I left the cover off tonight and will test ph in the morning.
