Used AlgaeFix in my 50-gallon pond during summer. The water cleared up within a week. No fish or plants were affected. Works well for green water and string algae.
Una Davies –
Good results after a few days of use. The algae in my fountain reduced significantly. I still need to aerate the water, but it’s a solid solution for algae control.
