API POND ALGAEFIX Algae Control 8-Ounce 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.

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!

I have used this twice now its cool weather but the algea is thriving. seems to have grown since i used the algea control.

I have a 200-gallon "water feature" (a.k.a. frog pond) in my Chicagoland back yard which in past years, despite vigorous aeration from a waterfall, would only survive about a month before algae took over. In summer 2015 the situation hit a new low with a snail infestation! The snails glommed-on to the pump intake, which slowed the volume through the waterfall to a trickle, which essentially eliminated aeration, which allowed a massive algae bloom to take over. Whattamess! For 2016, I vowed to fix the situation and I did two things differently: 1. I built a home-made milk crate filter and put the pump inside it (described here: [mvwgs dot org]), and, 2. Bought me a jug of Algaefix and used it regularly. Results: After 3 months of operation in hot weather where many ponds in my area are covered-over with algae, my pond water is clear and there is a minimal amount of filamentous algae attached to the rocks. This type of algae is flimsy, stringy, and easily pulled out with a rake if you keep after it. There are 7 frogs happily living in the pond, yet only a dozen or so snails have survived and been removed from the pond this year. Bottom Line: I don't think that the milk crate / lava rock filter would have done the job by itself and I don't think Algaefix would have, either. The combination of the two (with the Algaefix being used at a liberal dosing rate), plus some weekly maintenance (rake out the whispy filamentous algae), has been very effective.
