Algae-Off will help remove string algae from waterfalls, streams and rocks in seconds. Use the maintenance dosage of Algae-Off once a week and eliminate complete pond shut down for yearly clean-outs forever. Algae-Off will also keep fountain intakes clean and remove unsightly scum and algae from the perimeter of any size pond. Algae-Off is your personal pond cleaner in a bottle, without the time, money, mess, effort to catch the fish, drain the pond, wash and scrub the scum in the pond, refill the pond and put the fish back in hoping you don’t stress them and kill them. This 4-5 hour process can be eliminated forever by simply treating your pond once weekly with Algae-Off.

Apply Algae-Off® directly over the infected 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, Algae-Off® is not as effective with this application method.

This website is in memory of Samson, our white German Shepherd and Delilah, our Doberman (pictured on many of our pages) . Samson succumbed to liver failure on 12/20/2009. He was the best friend that I've ever had and will be deeply missed by all that knew him. Without him, we would never have started North Coast Pets. On 5/05/2015 Delilah joined Samson at the Rainbow Bridge. She was 12.5 yrs old. Now she plays with her Samson until we are together again.

Hug your pet whenever you can.
You never know how much time you will have with them.
