Do that, and you don't have to worry about aeration or lowering the alkalinity. Just don't raise it (no soda ash or bicarb) and don't add calcium, and let it come down on it's own over time. Check every week or so, so you don't get it too low.
Well, that sounds simple, so I'm on it. However, it raises a couple of questions for me:

1. I thought I'd read on here where the acid/aeration approach was really the only way to reduce the TA. You are saying that just maintaining low pH will reduce the TA over time, right?

2. Is a pH of 7.0 or 6.8 "swimmable"? Does it represent any hazard to our new liner?

3. What problems does the high TA present until reduced?

Thanks, Ben.
