GreenClean® Algaecide | Fast-Acting Non-Copper Algae

Control for Ponds & Lakes

Keep your pond clean and clear with GreenClean® Algaecide, a fast-acting, peroxide-based treatment formulated to control algae without the use of copper. Ideal for ponds, lakes, water gardens, fountains, and other water features, GreenClean® begins working on contact to reduce algae growth, improve water clarity, and restore the natural beauty of your water.

Unlike traditional copper-based algaecides, GreenClean® uses an oxidation process to quickly break down nuisance algae. As the active ingredient decomposes, it releases oxygen back into the water, helping support a healthier aquatic environment without concerns about long-term copper accumulation when used according to label directions.

Suitable for both preventative maintenance and active algae treatment, GreenClean® is an excellent choice for pond owners seeking an effective, environmentally responsible algae management solution.

How It Works

GreenClean® uses an active peroxide-based formula that rapidly oxidizes algae cells on contact, causing nuisance algae to break down quickly. As the treatment naturally degrades, it releases oxygen into the water, supporting overall pond health without leaving long-term chemical residues associated with copper-based products.

For best results, begin treatments early in the growing season or at the first signs of algae growth. Heavy infestations should be treated in sections to help maintain adequate dissolved oxygen for fish and other aquatic life.

Always read and follow the product label for approved aquatic uses, application rates, target algae, and safety precautions.
