Product Description
Fast, Practical Control for Algae-Heavy Water
GreenClean PRO Granular Algaecide 50 lb gives you a fast, visible way to knock down algae without the handling complexity of liquid treatments. The granular format lets you place product exactly where blooms are active, whether along shorelines, across surface mats, or in targeted zones. This makes it easier to respond quickly to problem areas while maintaining control over how much product is used and where it goes, especially in larger ponds and managed water systems.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| Granular oxidizing formula | Breaks down algae on contact without copper accumulation concerns |
| Broadcast application | Quickly treats large areas or targets specific problem zones |
| High active content | Delivers strong treatment performance per application |
| 50 lb commercial bag | Reduces reordering frequency for ongoing maintenance programs |
| Multi-surface use | Works in ponds, lakes, water features, and similar environments |
Directions & Dosing Snapshot
| Use Case | Label Rate | Application Notes |
|---|---|---|

We stock trout and can't use copper. This attacks the algae quick and takes care of floating and bottom. Thank you folks!

Product arrived in good condition and worked well.

This was the only product that has worked on the alge after trying for 3 years. Needed 6 bags to correct our entire pond.

We have alot of animals on our 5 farm ponds and since copper is out, have to use this. Works pretty good and won't bother the sheep.

This stuff works fast. It starts bubbling in minutes. Green water turns clear in days!

We switched to GreenClean PRO at our manufacturing plant after copper and all the usual chemical algaecides got banned by our NPDES permit. Applied it by boat across our 5-acre wastewater impoundment and the results were impressive. Filamentous and blue-green algae started browning and sinking within hours. No fish stress, no residual chemicals, and our discharge numbers stayed perfectly in compliance. We've been using it preventatively every few weeks during summer and it's cut our maintenance time in half. Highly recommend it for any industrial pond where copper is off the table.

Works great. But a little pricey.
