Here are my test results for today.
pH 8.0 (btwn 7.8 and 8.2)
The pH has trended up from 7.2 to 8ish over the last 5 weeks. I think that means I need to add some muriatic acid, correct? What should I target for pH? I was thinking 7.5 but in reading posts on the forum, I've seen Richard mention targeting 7.2 in a few places to help eliminate calcium scaling. I have no idea if scaling is a problem at this point in my pool. I'm also told I probably only have a 3-5 years left before it needs to be resurfaced so I'm not all that worried at this point about a little scaling. (The pool is new to me this year.)
Thanks in advance for any help.
