My ph has been climbing from about 7.2 to 8.O in a weeks time. I've been adding muratic once a week to bring it back down. Over the summer the fountains ran daily and I assumed the aeration was causing this. The fountains have not run for several weeks now and it still uses the same amount of muratic.
Also. It has been a while (aug?) since last time I checked my calcium. Last time I checked it was 290. Today it 490. I don't know why?
I only chlorinate with bleach and do not add any shock or etc.......
