I live in a hot and hard water area of the country. Fill water is 275ppm CH, 7.4 pH, 160 ppm TA as tested from my aerated kitchen faucet (running really slowly to minimize aeration.) Since I now have an SWG (and a calcium ring on the spa tiles,) I'm trying to keep CSI slightly negative (by targeting 7.2 pH) which is proving difficult with pool water CH between 725-775ppm (I can't seem to avoid a fading endpoint no matter what I try) high water temps (wife likes it around 90 F) that high fill TA and the SWG's aeration.
Is there anything I can do or am I just resigned to having to add 1-2 quarts of acid every couple of days? (Which admittedly isn't bad unless I go out of town for a couple weeks.) I'm loathe to drain and refill from conservation and financial standpoints.
I do have a solar blanket I keep on to minimize evaporation until the water gets over 92 degrees and I have to let it evaporate overnight to cool down. (That cover has paid for itself in just a couple months!)
