API pond ALGAEFIX Algae Control Solution 1-Gallon Bottle

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

This product works very well. Fish are very happy and I have a beautiful pond once again.

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!
