pool clear, here are my test results-what next?

[Bob_Funk]

Hi everyone,

My pool is finally clear & cc<.5 & fc is holding overnight

FC-12.5
CC-0.5
TA-110
CH-80
CYA-50
pH-7.2

I know the pH reading may not be correct with my chlorine level but it will drop by 1 tonight & probably 2+ tomorrow with the sunny day, so I will retest pH tomorrow night

What else should I do? Pool calculator says get CH up to around 260, anything else?

thanks

Bob

Finally clear and FC is holding!

Keep an eye on your pH. When FC drops below 10, I'd aim for 7.5 pH.

I'd actually bump the pH up a bit with borax. That's what I'd do.

With a fiberglass pool, CH is not so critical either.

Actually it is, you do want the CH to be at least 220.

"Critical" is a subjective word. With plaster having low calcium can cause significant damage to the pool. With fiberglass low calcium will slightly shorten the lifetime of the gelcoat and increase the chances of metal stains. I would say that calcium is critical with plaster and important with fiberglass.

Maybe I was mixing up vinyl and fiberglass? I thought there was some situation where low CH didn't matter.

Vinyl doesn't care about low CH levels. All pools care about high CH levels.
