For pools that just need TA substantially reduced once/season, and w/o any other obvious/good sources of surface water airation, would an aerator/air pump generally designed for ponds work? I'm looking at the "Danner 04560 Pond Aeration Pump with Diffuser, 3600 Cubic Inch/Minute" on Amazon which seems to imply that it could inject quite a bit of air into the bottom of the pool using just itself and some cheap tubing.
Alternatively, I've looked at getting a high powered submersible water pump and connecting it to a hose and then to a standard spray nozel that I could somehow stabilize over the pool for a few weeks/year. However, the pumps tend to be more expensive and some of them have the potential to leak oil or could get corroded. The air pump seems more reliable and easier to take out/put in once each season.
I'm just not sure how much airation the pumps produce versus what is needed to substantially reduce TA.
