What customers say
Customers highly value this product for its powerful, rapid oxidation capabilities. Its primary strength is quickly restoring water clarity and sparkle, allowing for earlier swimming compared to traditional shocks. The chlorine free nature is a major benefit for users sensitive to odor or managing high Cyanuric Acid levels. Application is easy as it dissolves quickly without residue. While performance is excellent for routine maintenance, the premium pricing is a consistent point of friction for many users. Some feel the cost makes it a specialized tool rather than a regular purchase. It is best suited for oxidation needs, as it is less effective against severe algae.
