New pool this May and I have no idea why my CH is at 520. I checked it two days in a row and got the same result- 52 drops x 10 = 520.
Pool calc says replace half of my water. Before I do that, I'd like to know why it may be in the 500s in the first place, or it may just go there again.
What causes CH to rise?
What effect does too high of a CH count have?
And yes, the 8.2 is too (****) high. Every time I turn around the pH has shot past 8.
4 cups of muriatic acid gets it back down but it just goes back up in a matter of days.
