Sanco Industries 88015 Fountain Algaecide, Clarifier Formulated for Small Ponds and Water Features, 8 ounces,1, Yellow

used it for my indoor table top fountain. seems good so far

FINALLY found something that killed all the green algae in my decorative, cement 2-tier water fountain, AND KEEPS IT AWAY! Been using fountain water cleaning solutions for 1-2 years from a national hardware store that kept the fountain water clear for about 1 week, BUT ONLY AFTER I DUMPED ALL THE FOUNTAIN WATER myself, and refilled the fountain with fresh water. Never really solved the problem; green algae. However, Fountain Algaecide and Clarifier does the trick. Dumped all the old water out of the fountain 2 weeks ago, added a capful of this incredible algae-terminator solution, and my fountain water is still running CRYSTAL CLEAR! IT'S AMAZING! Since I just started using this miracle working solution, I'm not sure how long that capful of potent formula will keep the water fountain's water clear. So, I'm going to sit-tight, keep my eyes on my water fountain, and when the water starts to turn green with algae, I'll then know the run-time for a capful of this dynamo solution, dump out the fountain water, and start all over again. (I believe the bottle says add one capful per week, but I'm going to test it and see how long one week's application will last before I have to start over, and begin administering the solution weekly, as the bottle suggests. After 2-3 years of trying to find a water fountain water clarifier, I've FINALLY FOUND THE SOLUTION! I'm an INCREDIBLY SATISFIED CUSTOMER! If you're having problems with green water fountain water, BUY THIS PRODUCT!!!

Works great in my backyard fountain to keep the water clean.

We have a tall fountain that the birds and honey bees love but in the summer heat algae is a problem. We use one capful of Fountec once a week and the water stays crystal clear. It is best to start with clean water although it will definitely reduce algae that has already formed. The bottle says it is safe for animals, birds and bees, and that seems to be true... but not safe for fish.

I had a lot of algae on my water fountain, and I scrubbed some off before treatment, but not a lot to see what it would do. It did clear up a great deal of the algae in a day or so where there was a lot of flow. In the more distant areas, it took some off, but I had to take a brush to those. So it looks like if you start with a reasonably clean fountain, it will keep it that way. Definately keeping the water crystal clear. My fountain is in a shaded area and doesn't get much sun so algae builds up fast. I will continue to use it.
