    • Best pool shock FOR SUMMER SEASON
Style: Bag Size: 12 x 1 Pound
I bought Cal-Hypo Granular Sanitizer for the low price. I have a 20,000 gallon pool. In the summers tha algae used to be a issue. However since using Cal-Hypo Granular Sanitizer that algae has become a non issue. I have used two bags and they last well into two weeks of algae free period. The second benefit is this product is cyanuric acid free which can lead to the infamous chlorine lock. Awesome impressive product. ... show more

    • It works great!
Style: Bag Size: 24 x 1 Pound
I have a 14,000 gallon inground fiberglass pool and have used calcium hypochlorite sanitizer for years. I recently switched to In The Swim Pool 68% Cal-Hypo Shock. It works great and seems to leave less residue than my previous sanitizer.
