Product Overview

Crystal Blue Copper Sulfate is a powerful algaecide intended for use in large ponds, lakes, and other extensive water systems where algae growth has become established. It works by disrupting algae cell function, making it effective against a wide range of species including filamentous and string algae.

This product is intended for application in actively growing algae conditions, particularly when water temperatures are above 60°F. It is most effective when applied directly to visible algae mats, allowing for targeted treatment of problem areas within larger water bodies.

Important: This product is not suitable for small decorative ponds, water gardens, or systems containing sensitive fish species due to its high copper concentration and potential toxicity to aquatic life.
