    CYA question

    Hey all, I'm a recent converter from Baqua so although I know those chems like the back of my hand I am in the process of really learning all the ins and outs of chems for chlorine pools.

    Got a question about CYA. I did a test and i have my CYA at around 40 which was my goal, I understand about getting the CYA down you have to replace water, so I have a question about standard evaporation. Does CYA get lower (quickly) from normal evaporation and water replacement. I expect as usual to replace 1 - 2 inches of water a week. What is everyones normal testing cycle for CYA (once a month, once every 2 months, etc). Thanks

    Evporation and refill does not reduce the CYA.

    I check mine about 4 times each season.

    I usually check mine like Duraleigh unless I suspect a problem with it.
    Don't have a pool right now. Just sharing what I have learned over the years!
