    POOL WINTERIZING CHEMICAL KIT - PLUS THE WINTER PILL!

    Unlike chlorine-based winterizing pool chemical kits that can stain, bleach or damage pool liners and other surface types, our winter chemical kits won’t damage your pool during winter. Our unique winter pool floater removes carbon dioxide, one of algae's primary food sources. Stain Away prevents staining while your water sits over the winter months, and a powerful winterizing inhibitor controls algae growth from the time you close until the time you open. Our non-chlorine winter pool shock kills micro-contaminants, algae and pathogens so your water is sanitized before you cover it up.

    Best of all, we have combined all of this with our best-selling Winter Pill! The Winter Pill contains enzymes, clarifier, and an additional stain and scale treatment so your water has double the protection while enzymes go to work eliminating waterline stains. Slow-release winter ball is a very popular customer add-on!

    As a bonus, we include the Winter Sorb™, which soaks up any leftover suntan or body oils so your water has every possible protection available!

    Pre-measured for your specific pool size. Ordering a kit larger than your pool size will help protect from winter cover problems.

    - Small Kit: for pools up to 7,500 gallons
    - Deluxe Kit: for pools up to 15,000 gallons
    - Super Kit: for pools up to 35,000 gallons
