    CYA and Temp

    I have searched he website about CYA and temp. I understand that low water temps can give false low CYA readings. What about the other way around? My pool is 87 degrees and I am testing CYA at that temp. Does testing at this temp affect the CYA?

    Thanks

    No. The low water temp just slows down the reaction when mixing the reagent, so if you do not let the water warm up, you may get false readings.

    I keep reading low water temps may result in low CYA readings, but no mention of below what temp is considered low?

    Anyone?

    I see mention of room temperature. So, I would think below 70 might start to introduce issues. Note, if you let the water warm up there is no problem.
