In The Swim Super Algaecide is designed for both above ground and inground swimming pools, specifically targeting yellow/mustard algae. Its key strength lies in the 7.1% chelated copper concentration, which is effective at preventing algae growth without causing pool staining.

Compatibility is another plus, as it does not contain harmful chemicals, making it safe to swim in the pool immediately after application.
