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

Works as described. Cleared the algae in my water lilies/goldfish pond, which sits in direct sunlight.

Went into August with crystal clear water in my koi pond... Until algae decided to take over. The water turned green and I couldn't see any of my fish. I came across this product and gave it a shot. Took two doses, and my pond is almost back to crystal clear again. The directions are easy to follow. This product works! And the 21 fish I have in my pond are all doing fine. Highly recommend if you need to clear up your pond. Just make sure you read the directions! You need to keep the pond aerated while using it. I have 2 aerators and a waterfall.

Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation.

I had purchased the smaller container of this product, and it works well, so I decided to buy the larger one since I'm experiencing a heavy bloom of algae in the South Florida sun and Heat. The product works. It can kill the algae, but much of it remains intact on the pond walls. You'll need to brush it off the walls and then try to remove it from the bottom.

Worked great for clearing algae! We used this in our 145-gallon outdoor tank with goldfish and lily pads. We’re in Central Texas where it’s been super hot and sunny, and the algae was getting out of control. After the first treatment, the water was still a bit cloudy, but after the second treatment (about 3 days later), it cleared up beautifully. We didn’t lose any fish or plants, and everything looks healthy. We plan to keep using it weekly through the summer to stay on top of the algae. For reference, we run a filter and an air stone full time. Very happy with the results!

It took a year to remove the Algae. The water is currently clear. I did add chlorine tablets to the water.

This product was amazing for my pond. I went from having green water to clear water. The hardest part was gauging how much to use initially because I built a pond where an 80 foot palm tree had existed before we dug it up. My pond is between 200 - 300 gallons. So everything for me has been learn and adjust as you go. I followed the instructions, pour 'X' amount (based on gallon size) for 3 consecutive days and then once a week after that. I have 2 yellow belly turtles, 16 goldfish, 4 kois, 15 minnows and 4 plecos and an undetermined amount of local snails that I have 0 idea how they moved in, but they did, and none of them seem affected or bothered by this product. Definitely recommend, worth your money.

Tried others none of them worked as well as this one did! We didn’t have any mold or algae all summer, water was crystal clear. Will purchase this again and again! Recommend highly for water fountains.
