    when closing pool, chlorine level for adding poly quat?

    when closing pool, chlorine level for adding poly quat?

    I have a mesh cover.

    Will Poly quat last the whole winter and allow me to open up without a green pool?

    Or would i be better off adding poly quat in the spring couple months before opening?

    I add it on the closing and try to open early. It seems to be a case of YMMV. It's best to have the pool as clean as possible and balanced when you close it up.

    Remember it is thick and needs 24 hours of pumping to get distributed. There are some threads on the use of it and I had found one where chem geek posted the manufacturers recommended process. What I recall was that they suggested you "shock" for a few days at 5-10 ppm first, and then let the FC drop back to normal levels. Based on that I would say you should shock, then when OCLT is passed, let it drop to your normal level then add polyquat and mix for a day, then close.

    But there are more expert opinions that should chime in.
