On the last comment, I have fill water at pH 8.5 and TA ~250 !!!. (Coming from a well, and I tested our tap water, but I'll confirm on fill). Just using some rough rules of thumb, I'm guessing that to get to what I need, I'm going to be putting 10s of gallons of muriatic in the pool? And If I drop to 7.0 then aerate, thats going to take on the order of months to get balanced? Can this be right? And is there a faster way? I'll be doing this all summer...and get it done just in time to winterize...
