Hi all, After treating my pool with MA, it really did the trick of lowering the PH and TA well (in fact for the first time ever I had to add soda ash to bring it up), but a couple days later the PH was higher than I've ever seen it. I put 3 oz bisulfite in, waited about an hour, and it lowered it some (still looked a hair below 8.2), but not enough, so I put 4 oz more in. An hour later it still looks like a hair below 8.2! Do I just keep dumping in bisulfite?
My aqua chem chlorine drops are reading more or less perfect (between 1.5 and 3) on the chlorine level, but then I tested with an Intex test strip which measures Free Chlorine, and it shows the lowest mark (0.2). Which one do I trust?
I know they say strips are notoriously inaccurate, but the PH And alk readings seem good on it.
