This product works well in small ponds, but is too expensive for a large pond. I have a 24,000 gallon pond. 50 lbs will not keep it clear for a year. People with acre size ponds will go broke tryin…

Green Pro

By Floyd in Cypress, Texas on 04/22/2012

Applied as instructed it looked like it worked at first but the algae soon returned. For 155 dollars this is not worth it... It just does not do a good enough job. I will not buy this again..

Works Great!

By Linda in Paso Robles, CA on 07/29/2011

Works Great on String Algae. I gave some to a friend and he said, "I'm gonna order some!" Soon as you throw some directly on the algae you see it start to foam. It doesn't kill the fish.
