How To Apply

Apply AlgaeOff™ directly over the infested area in granular form. Surface should be wet or water should be applied immediately following application. For waterfall applications, turn off waterfall pumps and allow Algae-Off™ to sit on the waterfall for a period of 20 minutes and then turn pumps back on. Skim the dead algae or organic material that rises to the water's surface after treatment. Allowing dead organics to sink and decay will provide a food source and additional nutrients for future algae blooms. Allow 48 hours between consecutive treatments.

For liquid applications, please follow all label instructions. Due to solubility, AlgaeOff™ is not as effective with this application method.

When To Apply

AlgaeOff™ should be used any time string algae has accumulated on rocks, streams and waterfalls. Water temperature has no effect on AlgaeOff™ but higher temperatures enhance effectiveness.

Restrictions

After application, do not allow undiluted AlgaeOff™ granules to remain in an area where humans or animals are exposed. Make sure all granules have been sprayed with water to fully dissolve.

"Waterfall Looks Great!"Shane of Girard, KS

After using a couple products to remove the string algae from my waterfall & stream rocks, I tried Algae-Off. IT WORKS! It is easy to use, works great and now is a regular part of my pond routine.
