What Customers Are Saying
Customers overwhelmingly praise this pool shock for rapidly eliminating algae and restoring crystal-clear water within hours or by morning. Many highlight the pre-measured packs that require no mixing—simply dump in the deep end—making weekly maintenance effortless for both above-ground and in-ground pools. Reviewers consistently report dramatic results clearing green discoloration and hazy water, especially after heavy rain. The brand earns deep loyalty, with many customers using it for years and comparing it favorably to competitors for superior clarity and chemical balance. A few rare cases mention dissolution issues, but these represent minimal feedback vastly outweighed by overwhelmingly positive results.

Keep an eye out for clorine percentage when buying
Would RecommendThe product is fine. Would be nice due to the fact that you buy in bulk, that the prices be lower. Everybody's on the cash/cow with chlorine prices.
