A commercial strength liquid algaecide for treatment and control of algae conditions in backyard water features.

Suppresses, controls, and prevents algae in water gardens and fish ponds. 

For use with string algae and planktonic algae. 


Clear Water & Healthier Ponds start with GreenClean. 

GreenCleanFX Liquid Algaecide is ideal for green water algae, can run through your system removing algae throughout, and works even in cooler waters – making it ideal for pond openings. As an EPA-registered algaecide, it is compliant with the USDA National Organic Program regulations making it safe for use in water features containing fish, plants and other aquatic life.
As an added benefit to ease pond maintenance, GreenCleanFX Liquid will not lead to an increase in water pH.

Continues to work up to 48 hours after application
Breaks down into water and oxygen leaving no residuals
Moves to the bottom making it highly effective in deeper waters

Reduces organic build up and odors

Ideal for pond openings & closings! 

Whether an initial cleaning when opening, during season on any species of algae, or for final cleaning before closing… GreenClean has you covered! 

Pair our algaecides with our specialized and beneficial aquatic products to take full advantage of a holistic and environmentally-friendly approach to the maintenance of water features. 

It is long-lasting: a 33 fl. oz can treat up to 4,850 gallons. Its packaging is easy to use with a tip-and-pour technology that measures for you. No mess, no guessing, just easy applications and beautiful water! 

GreenClean is an EPA registered, non-copper algaecide that outperforms the competition. Available in granular (for string algae), liquid (for green water algae) and tablets (for preventative). 

Why It's Better

Great for pond openings all the way into the cooler months making it the perfect choice!

The low application rates make GreenCleanFX Liquid Algaecide a highly effective and affordable solution to a wide variety of algae conditions. The chlorine, copper and phosphate-free formula makes it fish, pet and family friendly. Other products contain harsh chemicals, if used incorrectly it could be harmful to the fish, plants, and the balance of the water column.

One major benefit of GreenCleanFX Liquid Algaecide is it can be used in colder waters as algae can still be present in those conditions. You can use GreenCleanFX Liquid Algaecide in the spring as an opening application and use it throughout the season. It will also not lead to an increase in water pH like other products. 

GreenCleanFX Liquid vs GreenClean Granular:
GreenCleanFX Liquid Algaecide goes quickly into the water column and begins treating the system where GreenClean Granular is more of a spot treatment for waterfalls or string algae. So together they make an excellent program.

GRFX16: 16 oz

GRFX32: 32 oz

GRFXG1: 1 Gallon


For 500 gallon pond, use 5-11.6 oz depending on density of algae.

Repeat dose every 3 days until algae is under control.

After algae control is achieved, apply weekly maintenance dose.
