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

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.

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

I have a small decorative fountain that is battery operated and requires manual refilling. Because it isn’t much bigger than a bird bath size I wasn’t sure this would work. We’re in So California and the heat was turning it into an algae factory every day. I would manually clean and refill constantly but couldn’t keep up with the growth. After cleaning and adding clear water I added one capful. The water has been clear ever since, even though I’ve had to had more water due to evaporation. It’s been more than a two weeks and I haven’t had to add any more capfuls yet. I would definitely recommend!

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

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.
