What Customers Are Saying

Customers overwhelmingly praise this algaecide and clarifier for rapidly eliminating algae and restoring crystal-clear water, often within 12 to 24 hours. Many describe dramatic transformations from green, swamp-like pools to sparkling blue water. The dual-action formula is valued for combining algaecide and clarifier in one bottle, reducing the number of chemicals needed. Users appreciate its ease of use and fast results, with many stating they will buy again. A small number report it did not work for severe algae cases or required more product for larger pools, though most consider it highly effective and reliable.

reviews are not accurate

 Would Not Recommend

Why does the app say 33 of 37 recommend but there are many more than 37 reviews, and a ton of them say they do not recommend, even if they give a good review. This makes no sense.
