API POND ALGAEFIX Algae Control 32-Ounce Bottle, FISHAQUARI (169G)

I recently tried the API POND ALGAEFIX Algae Control in my aquarium, and I must say, it's been a game-changer! This 32-ounce bottle packs a powerful punch in keeping algae at bay, creating a clean and clear environment for my fish to thrive in. I love how easy it is to use and the results are simply amazing. My water has never looked better, and the fish seem happier and more active since I started using this product. I highly recommend it to any aquarium owner looking for a reliable solution to tackle algae issues. The only downside is the small bottle size, which may not be sufficient for larger aquariums, but the effectiveness definitely makes up for it.

Works good in pond approx. 40’ round & 17’ deep. Lady long time unless a lot of rain. Good value!

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.

Works awesome

Takes multiple uses but definitely did the job without harming any of the wildlife visiting my small pond.

Works, but be very careful!! It will kill your fish!!! I read the instructions and tried to aerate the pond as best as I could. Unfortunately it still killed all of my fish overnight. I can see the bottom of the pond now, but at what cost. Didn’t remove all the algae at the bottom however. There is still a lot that can be stirred up.

So I ordered this because I had an algae problem in my koi pond and followed the directions as closely as I possibly could. After adding the fish back to the water ( I removed them all for a deep cleaning of the liner ) I noticed somw of them acting weird and jumping and gasping for air , others were just lifeless on the bottom, a couple goldfish seem to have even aquired neurological problems. Doing the twirling death spiral and sinking to the bottom . None of them were eating , which is very strange as all of them had great appetites before. I had to act fast and remove them and do a 100% water change to remove all the product from the water. Luckily I managed to save them all . I DO NOT recommend this for fish as it is clearly not safe. Even if you have all the aerator and pumps going as I did. Maybe safe for fountains with no fish or plant life? I threw the rest away and would NEVER buy this product again. Almost cost me hundreds of dollars in livestock as my koi were very expensive.

Product resolved my pond’s algae problem.
