Used AlgaeFix in my 100-gallon pond after a summer algae bloom. It cleared the green water within 3 days. My koi stayed healthy and the plants looked vibrant. I followed the dosage instructions carefully and didn’t need to add any additional treatments.

Good product for controlling string algae in my fountain. It didn’t harm the fish or the water lilies. I measured the pond volume first and used the recommended amount. Works well in moderate conditions.

After several months of algae issues, AlgaeFix solved the problem. The water became crystal clear and the fish seemed more active. I’ve used it twice this season and it’s reliable.
