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!!!

We have a waterfall garden, and it tends to green-up easily. It also has string algae. We added this to the flow, and lo and behold, it cleared up in two days! Would buy again!

I've used this successfully for several years. It does the job just fine. I usually add it to my waterfall several times during the Summer until the very small bottle is gone. This year, the algae monster visited earlier and was more stubborn. I had to add the entire contents before it cleared up completely. Great stuff, but I'm going to have to reorder if we have a problem later in the season.

This stuff works great. Keeps the water clear and you don’t have to use much
