Used AlgaeFix after a sudden green water bloom in my pond. It worked within a few days and reduced the algae significantly. My fish and plants seem unaffected. Easy to mix and the instructions are clear.

Good product for controlling string algae. I added it once and saw improvement in a week. Works well with my existing plants and fish. Would recommend for small to medium ponds.

The algae in my pond had grown out of control. After using AlgaeFix as recommended, the green water cleared up. No fish stress or plant damage observed. Very effective and safe.
