      Rated 5 out of 5 by from Great results We had a strange winter and the weather here in Texas created havoc on our pool. I would recommend these sanitizing granules for year round pool maintenance. It even worked on a pool stain we've been trying to remove for a while now. Buying in bulk from In the Swim is recommended, it saves a good amount of money in the long run.

      Rated 5 out of 5 by from Excellent Product I have been using this product for many years now. It is easy to use and fast acting. I have a 36,000 gal. pool so I seem to use a lot but for what the product does it is great. Would suggest this item if you use shock regularly. Thanks for such a great product!

      Rated 5 out of 5 by from Keeps pool sparkling The granulated shock is easy to use and dissolves quickly. We prefer this to the packaged shock. It works just as well and leaves less waste (plastic packaging). It's effective at keeping our pool water clear and sparkling. It looks so inviting!! We live out of the 1 day delivery zone, but we still received our order very quickly, which is important to me. I've ordered this product from In the Swim for several years now and have been very pleased, both with the product and the service.

      Rated 5 out of 5 by from Much Better than Granular Chlorine I had used granular chlorine for years up purple stains (copper?) started forming on the pool walls. Then I switched to calcium hypochlorite. It is much more effective, and no copper stains or algae in two years. It is a bit more expensive, but it works. One minor problem: Unlike granular chlorine, you have to be home to sign for the delivery of calcium hypochlorite.

      Troubleshooting:

      – If chlorine seems ineffective make sure you are dispensing the correct amount of chlorine. For best results, dissolve in water before adding to pool.

      – If using as a weekly shock you will use 16oz. per 10,000 gallons.

      – If using as your main sanitizer you will use the following:
      – For unstabilized pools use 6-8 oz. per 10,000 gallons daily.
      – For stabilized pools use 3-4 oz. per 10,000 gallons every other day.
      – Dosages may vary to keep chlorine in 1-3 ppm range.

      – If chlorine still seems to be ineffective check the stabilizer also known as cyanuric acid. The correct level for stabilizer is 30-60 ppm. If the stabilizer is too low the chlorine will be used up faster making it appear that the chlorine is not effective. If the stabilizer level is too high it will slow down the oxidizing process and render the chlorine less effective. This must be compensated for by using a higher concentration of chlorine in the pool water.

      – If the chlorine seems to be defective/ineffective, you can test by putting a small amount of Cal-Chlor into a glass of tap water. (Do not use pool water.) Dissolve and test as usual.
