Cloudy pool, pH seems locked

[HokieMatt]

I normally run around 3ppm and never have algae issues. I noticed the Cl level had dropped and I attributed it to the reduced filtration/SWCG runtime combined with rising temperatures and more sunlight.

I'm going to have a hard time letting the pH thing go, I need to know why the soda ash didn't raise it. I haven't added CYA in weeks and don't use dichlor/trichlor or any other acidic chemicals, so I'm puzzled as to what could be offsetting the pH increaser.

OK, suit yourself....

We try to keep people from "chasing numbers", and just get the water balanced right for a clean, clear pool that they can enjoy. However, I realize that to some, the pool becomes more of a hobby than the swimming. So...I won't try to answer your pH question. There are some chemists on the forum who might. However, right now we're all pretty swamped trying to help people who are trying to get their pools swimmable, so you may or may not get another response on why youre pH isn't rising. I hope you understand

No problem at all, I realize my "problem" really isn't one at this point. I've ordered a new K2006 test kit, once that arrives I may well find out that all my readings were bogus due to expired reagents.

To update my water situation, you were right about the impending algae. A couple of days ago I checked chlorine level in the morning before the SWCG was running and found it at zero. Brought it up to about 10 with cal hypo shock and kept it there for 24 hours, after which it was crystal clear and has stayed that way for 48 hours with no other chemical additions. Chlorine level holding overnight, so it looks like the problem is solved. Thank you for pointing me in the right direction.
