I'm having a long-term problem with cloudy water, especially noticeable in the deep end (9 feet deep). It started last season and is continuing into this year. Could a low calcium hardness value be the cause?
Here's why I ask - In 1978, my first job out of college was managing a community pool. "Junior olympic" size (about 25m by 10m) with a 12-foot deep diving tank. I'm guessing about 150K gal. Gunite, plaster finish, about 20 years old. With balanced water, I slowly began to have a cloudiness problem. "Experts" suggested that low CH was causing calcium to leach out of that old plaster. Solution was to add calcium chloride (a lot!) and it worked overnight like a charm.
My current numbers:
FC - 13
CC - .5
pH - 7.7
TA - 120
CH - 120
CYA - 90 (Yeah, it's high. That's why my FC is 13.)
Temp - 80
Filter runs 24/7.
What say you experts?
