Our pool is only a month old. Just when I get a couple of the readings balanced, then others go out of whack. I hate to get in the habit of adding things constantly.
I started using BioGuard BackUp, due to " Boatmen" bugs. Shocked the pool, and now the bugs are gone. Seems like the TA and PH keep bouncing daily. I treated it today with Calcium Hardness Plus. All pumps running full force, due to freezing temps.
