BioSafe Systems GreenClean Granular Algaecide — 8 lb | EPA-Registered, Copper- and Chlorine-Free Pond & Water Feature Treatment

BioSafe Systems GreenClean Granular Algaecide is an EPA-registered, chlorine- and copper-free granular treatment that kills string and blue‑green algae on contact while remaining safe for fish and aquatic plants when used as directed.

GreenClean Granular delivers rapid oxidation of algae cells and begins working immediately after application. Its biodegradable organic chemistry breaks down algae, releases oxygen into the water during biodegradation, and is formulated to be non-harmful to stocked ponds, fountains, waterfalls, and other decorative water features. Because it contains no chlorine, copper, or phosphate it’s a practical option for residential and ornamental waters where aquatic life and plantings are present.

How quickly will I see results after I apply GreenClean?

GreenClean starts working on contact; visible decline of string and blue‑green algae typically appears within 24 to 48 hours under ideal conditions. Sunlight and warmer temperatures speed the product’s activity, so timing and weather affect how fast you notice improvements.

• Visible algae breakdown often within 1–2 days.
• Best applied on calm, sunny mornings for maximum effect.
• Higher water temperatures accelerate oxidation and biodegradation.

Can I use this product in a pond that has fish and plants?

Yes. GreenClean is formulated to be safe for fish and aquatic plants when applied according to label directions. It’s EPA-registered and free of chlorine, copper, and phosphate, reducing common risks associated with harsher algicides.

• Approved for use in stocked ponds and ornamental water features.
• No copper means less risk of metal buildup affecting plants or invertebrates.
• Follow dosing instructions closely for the size of your water body.

How much water will an 8 lb bucket treat, and how is it applied?

An 8 lb pail of GreenClean treats up to about 16,000 gallons, making it suitable for small to medium residential ponds and multiple decorative features. Application is straightforward: broadcast or spot-treat granules directly onto algae-affected areas or over the water surface, then allow the product to work.

• 8 lbs treats up to 16,000 gallons total at labeled rates.
• Apply directly to visible algae or distribute evenly over problem areas.
• Repeat treatments as recommended on the label for persistent blooms.

Is GreenClean a preventative option or only a curative product?

GreenClean functions both as a curative for active blooms and as a preventative measure to reduce recurrence when used periodically. Regular monitoring of water clarity and prompt spot treatments help maintain balanced aquatic environments.

• Use as-needed to knock down active algae growths.
• Periodic maintenance dosing can reduce future blooms.
• Combine with good water management for best long-term results.
