    This stuff is amazing and works right before your eyes. It will take us several treatments to undo the two years of no maintenance the pond has endured before we started caring for it, but you know this stuff works because it kills the algae immediately. We could see it peel off the bottom of the pond, turn brown, and float to the surface. When it was done we did some skimming to get the dead algae off. We combined this with some REGEN-Sediment to control the string algae, which is starting to turn brown and die. All in all they both work well together and are helping us to control the algae problem. If they don’t work for you right away, you might need to step up your dosage, and in the more extreme cases, it will require more than one application. But you will need to clean up the aftermath, this isn’t a “set it and forget it” thing.

    Best pond product I have ever tried! I have been buying the liquid stuff I get from another company with minimal results. I decided to try this granular Algaemaster product and was absolutely blown away by how well it worked. Visible results started immediately. My pond has never looked better and it did not harm any of my other water plants! So glad I got this!

    Initially I thought it didn’t work. I went through a whole bucket of REGEN-Algaemaster and algae was still coming up. I had to scoop lots of it out and was starting to think I was fighting a losing battle. Then suddenly it turned a corner and (together with the pool dye cutting out photosynthesis, allowing algae growth), I’ve had almost no algae for weeks now. I can again swim in my pond and the ongoing maintenance has been minimal. I just check every few days and put a small amount on any algae I can see forming. Virtually none. Highly recommend this product.

    When the product description says it offers immediate results when eliminating algae, I had to try it. This stuff worked great in my pond. I have goldfish and turtles. They are just fine. The algae is almost gone and I had a lot. I am definitely going to keep buying this to maintain my pond. Thank you so much. I love this stuff!!
