    Borates - do they lessen over time or just by dilution?

    Do borates eventually decrease because of air, light, etc., or just by dilution?
    Or is it once you add them, you always have them?

    Also, what if you go over 50ppm? What effect does it have on your pool?

    I believe borates stay where they are, much like CYA. I have more than 50 ppm, prolly around 60-65 (I had overestimated my pool volume). My water looks and feels great.

    I don't think it's harmful to have borates over 50, just doesn't offer any add'l benefits. Other folks here may have different info. [edit: the pH does tend to go high and I have to add acid a couple of times a week. Possibly I wouldn't have to deal with that if my borates were a bit lower.]
