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.

Drain a bit of your pond to speed up results and you won’t regret it
Works great! Fish and plants are safe, dogs drink from the pond and they are OK too ha ha 😅 I had bought a lily with a little bit of string algae and within a few weeks it was spreading and the entire pond was turning green so I looked up a bunch of different solutions and this seemed to be the safest and best results. I used as directed with about a quarter cup per 600 gallons and it did ok, but there was still major algae on my beautiful rocks so I drained the pond half way, let the sun cook the algae on the dry rocks for a couple days then mixed about 1/8 of a cup of the algae fix in a spray bottle of water and coated the stones where algae was and let it sit for a hour before filling the pond back up with hose water and turning the little stream back on and WOW 🤩 I can see the detail in the stones again with ZERO scrubbing and the stones under the ones I sprayed are also starting to clean up with crystal clear water!! Will definitely use when needed for ever

Fantastic Api Algaifix..Unbelievable!
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.

Works Well with Consistent Use
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.
