Best CYA Level for Lots of Sun - Location Hawaii

Thank you,

I'll go to 40 and let you know how that does. Then anyone from Hawaii will at least have an idea of where to go on this.

One final question, what would be the ideal drop other than zero in the level of chlorine for a not heavily utilized pool? I realize that the answer might be a little difficult as it is sun/UV dependant but maybe someone from Mexico City (around the same latitude), S.Cal or Arizona might be able to give some numbers.

Finally I'm worried about Walmart's stock price, it might drop if I stop going there for my truck load of liquid chlorine.

Ah, decisions decisions.

That's going to depend on your CYA level. See Ben's Best Guess Chart.

I built a pool when I lived in Honolulu and ran it at CYA of 40-50ish. I wouldn't raise your CYA level too much or you'll have to keep a higher chlorine level - and bleach is a lot more expensive in Honolulu! (I could never get over how much Times charged for a little bottle of bleach - Big K and Walmart were the places to go, even though I hated both stores.)

I wonder if you don't have something else going on - like fighting some algae that's eating up your chlorine?
