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.

HTH rocks!
The best pool products! Cleared up the pool fast and was free of algae in a couple of days. The water was crystal clear after using the clarifier. The water remained stable between treatments. The only product we will be using next year.
