    Help Cyanuric Acid in Bottom of Pool

    I read the back of the bottle and did as it suggested, sprinkle on top of the water in the deep end. Now I have Cyanuric acid granules in the bottom of my liner pool. Will this hurt my liner.

    Thank you!

    not sure about liner damage...it is a weak acid, but nevertheless I see three options

    1) if you have a center drain turn it on and brush the granules toward the drain
    2) if not center drain you can try vacuming...both 1 and two will have the cya settle in your filter, which is fine
    or 3) sweep it around evry few hours so it doesn;t sit on the same spot

    Good luck!

    If you do 1) or 2), make sure you don't backwash for a week while the CYA in the filter gets a chance to dissolve.

    This is just an update for anyone reading this in the future with the same problem.
    I did push the Cyanuric Acid toward the main drain and I did not end up with any damage to my vinyl liner.

    Thanks for the help, again!
