Right. The indoor pools aren't exposed to direct sunlight...so they don't benifit from the CYA.

thanks for the comments. While doin' some reading I found it just as fascinating that chlorine is effected by high/low PH readings as well as CYA and sunlight.

It's actually a good feeling to know why my water is clear and clean. I just hope it provides me a slight leg up should a problem come up
