EasyCareFounTec Algaecide and Clarifier, 8 oz. Bottle

I use this in the summer for my birdbath because the algae grows like crazy in the sun. Please be aware that this IS NOT a birdbath cleaner...you'll still have to clean from dirt, mud, dropped seeds, leaves, etc. I clean mine out about once a week, using vinegar diluted with water, scrub it and the decorative rocks really well, then rinse multiple times and refill. When I start refilling it, I pour a few drops of this (amounts are on the back of the bottle) under the hose, and it keeps the birdbath algae-free for weeks! Awesome product! :)

I've used this product for several years and it works great in the outdoor fountain on my patio. It only takes 1 or 2 drops per gallon of water. I'm in a warm humid climate in Arkansas and have no problems with algae while using this product. I also have dogs who regularly drink from the fountain so I can verify this is not toxic to pets when diluted in water according to the directions.

Great product. It keeps my fountain crystal clear for days, especially during the hot summer days!! Fleur de Lis Garden Ornaments in Olympia, WA recommended it when they set up my Fountain.

This works great for both of my fountains and prevents any green algae or slime from forming. Birds drink out of my fountains and this is harmless to any wildlife.

Best ever for keeping my pond clear and algae free!!

Keeps the water clean.

But unfortunately I still see a lot of allergy so. It does not work that well. It works but I think I'll go with another product next time

This stuff works great in the fountain. I should probably buy a larger bottle too.
