    Does this dissolve before hitting the bottom of the pool?

    Answer This Question

    Yes, this product dissolves quickly in water and should not reach the bottom of the pool if added correctly. It's important to follow the instructions on the packaging for proper application to avoid staining or damaging the pool surface.

    Is 68% hypochlorite safe for a liner pool or would it be better to go with one w/ less percentage?
    ByJun 7, 2022
    1 Answer | 
    Answer This Question

    No I do not think it is safe for a liner pool I think mine leaked from the bottom shortly after using this product

      I just bought a 10' x 30" inflatable pool with pump & filter. It holds 1,000 gallons of water. How much should I add to the pool? If 1 lb. treats 10,000 gallons of water, would 1/10 of the bag be enough? I hope my math is correct, TIA

      Answer This Question

      There are many factors that affect how much chlorine you need to add to your pool but I can tell you 1/10 of a bag is never enough it depends on where you live and how much sun your pool receives the more sun the more chlorine you need. I have an 18 foot round pool in Florida and during the summer I add one full bag every four days

        Doesn’t sound like much does it. Best to get test strips and add a 10th at a time until it gets to the proper level.

          Excellent results. Chlorine percentage is similar to other products, at half the price. Product dissolved well, and as long as your pool is balanced, it does not cloud your water.

          It was seamless ordering the Dry Tec shock from Home Depot. Excellent service and product.

          Can't ask for more from this product. 1 pack per week keeps the pool nearly clear of alge.
