All of my fish died after using this
I have used the directed amount as per the instructions. They died in 12 hours. I'm so upset and disappointed.

Amazing results on just two days. Two months of algae bloom due continuous rain and sunny weather. Never experienced this in with my pond before. Fishes could no longer be seen. Fantastic API Algaefix ... My pond is restored to be crystal clear again.

Great product, cleared my pound of an insane amount of hair algae in 3 days. Water lilies and fish show no signs of stress.

I use this in my 75-gallon front yard pond, which has 4 feeder goldfish and solid filtration. At first, I wasn’t sure it would make much of a difference—but after several applications, the water suddenly turned crystal clear. That said, it doesn’t stay that way long. We usually need to reapply once a week, and sometimes even hit it 2–3 days in a row when it clouds up again. In my experience, the dosage instructions are too conservative. The recommended amount didn’t do much, so I doubled the dose (safely) and that’s when I saw results. It’s a bit of a process, but if you stay on top of it, it really works. I’d give it five stars if it lasted longer between applications or worked faster, but overall it’s a solid algae control solution.
