I’ve used Algae Stopperz for three months now and noticed a significant reduction in green water and blanketweed. The pellets sink easily and work without disturbing my fish. No chemical smell or side effects. A simple and effective solution for my pond.

Works well in my filtered pond. I placed them around the edges and after two weeks, the algae started to clear up. I’ve added a new batch last week and it’s already showing results. Easy to use and safe for fish.

My pond had a lot of green water last summer. After using Algae Stopperz, the water became clearer and the plants looked healthier. I didn’t need to use any chemical treatments. It’s a natural and reliable option.
