    Closing Chemicals

    Our pool will be closed next week by our usual pool company. For the first time at opening, I instructed them not to add any chemicals as I now add them myself, thanks to BBB I know I have to shock for a couple days and bring down my PH (it was a little high at todays check)and add Ployquat. Do most pool stores have that? Is it called Polyquat and how much do I need? Thanks in advance.
    In ground 26,000 gal. 16x36 Avg depth-6'
    sand filter used 24/7
    auto cover

    Re: Closing Chemicals

    Most pool stores should have it. It also called polyquat60, if it is not obvious, look for the active ingredient that looks something like this:
    60% Poly[oxyethylene(dimethyliminio)ethylene(dimethyliminio)ethylene dichloride]
    Use the package instructions for the maximum/startup dose.

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
