Product Description

AlgaeFix is a fast acting solution for algae problems. It eliminates most infestations in one application. Though potent, AlgaeFix is safe for nearly all fish and plants when used as directed.

AlgaeFix controls green or green water algae (Chlorella), string or hair algae (Cladophora) and blanketweed (Oedogonium) in ornamental ponds. 

Available in Sizes:

16 oz - treats up to 4800 gallons

32 oz - treats up to 9600 gallons

1 gal - treats up to 38,400 gallons


Ensure vigorous aeration in the pond during AlgaeFix treatment. As algae dies, low oxygen levels can occur, which is dangerous for fish and plants, especially in warm weather.

Apply it in the morning, during the coolest temperature. Avoid applying it if the air or water temperature is over 85 degrees Fahrenheit.

Application Rate:
Apply 1 teaspoon of AlgaeFix per 50 gallons of pond or fountain water (1/4 cup per 600 gallons). Add it near the pump outflow, waterfall or aerator. Siphon out dead filamentous algae.

Reapply every 3 days until the algae is gone. Then add 1 dose per week.
