We have a 3 tier ceramic lighted fountain that we only run via timer during the evening for approximately 6 hours every day. It developed green algae even though we were treating it with an anti algae fountain formula of a different brand name. I decided to give this stuff a try since the other brand wasn’t getting it done. Well, I decided to give the fountain a “shock” treatment because the algae got so bad inside the fountain and even scrubbing it down and replacing the water wasn’t helping. Bam, using this stuff did the trick and we’ve had zero regrowth of algae since. That was about two weeks ago and still have a clean fountain and going by the dosage chart it will only need a cap full once a week for prevention. Liked it so much I ordered another bottle. So, price is very reasonable, it works and it’s relatively safe to use. Be mindful it could be potentially harmful to pollinators so it’s your judgement call.

The Fountain Algaecide and Clarifier provides superb results for my garden fountain. A capful every five days keeps the water clear and arrests algae growth. For my money, this product offers the solution to eliminating years of nasty green slime in my fountain. Bottom line: It works.

Clears my small fountain but doesn't prevent algae from eventually clogging the motor over time. Decently. I keep buying it.

I'm happy to report that it works! It's the first time i can see the bottom of the fountain since the algae appeared. What a pleasant surprise!

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!!!
