Fountain Algaecide and Clarifier - 8oz - Kills and Inhibits All Types of Algae Growth, Formulated for Small Ponds and Water Features, Treats up to 8,000 Gallons

Been buying this now for over a year and it really does seem to work well. The birds and dogs drink from the fountain and no one has gotten sick that I can tell so it is truly safe for animals. The algae is not nearly as bad as it was before I started using. I live in Texas and the heat an humidity cause algae to just flourish and my fountains would clog up. After we started using this the water stays crystal clear without any issues. Highly recommend!

This works MAGIC! I purchased another product on Amazon and had been using for months but the algae kept getting worst. I would have to completely shut down and clean my fountain very often and still there was constant growth. I decided to give this a try and it instantly cleared up my algae filled fountain and it has remained clean. The water is CLEAR! This is definitely worth the price and works.

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!!!

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.

Great product! It works. I was hesitant to purchase but it’s working.

After years of generally disappointing results from other fountain algicides, I decided to give this one a try. Bear in mind that my fountain is very small (perhaps about 2-3 gallons of water), so when you do the math on the recommended amount of algicide to use it literally comes out to a few drops. At this rate the 8oz bottle will last forever so for me the value is tremendous. I have been using this for three months so far, treating every 10-15 days and so far, there is absolutely no sign of algae whatsoever! And as I understand it, when used as directed it is not harmful to birds, humans or other animals (save perhaps fish). I know that this chemical is used in swimming pools as a chlorine alternative with no apparent risk so it seems like it would be OK. Obviously I'm not an expert and can't say with certainty that it is 100% safe, but what I can say is it works great for algae control.

Ok, totally honest review here. I put this in a small water feature, old and stained but freshly scrubbed, used less than a quarter cap full and on a 100 degree, sunny day when there would have been algae growth, I have none. Tomorrow is going to be another scorcher, so we'll see how it looks in the evening. So far, I'm pretty impressed. I did read the one star reviews after purchasing. . .what is being said is not exactly true. The "hazardous to humans and domestic animals" is only when exposed to the concentrated form, however, it says nothing about how potentially hazardous it is in its' diluted form (and it should, just like the Amazon description). I have a dog that drinks out of my water features, so that concerns me. I certainly don't want to poison my dog, nor do I want to poison any animals that use that water feature every day. So. . .I am torn. It definitely works on algae, but at what cost? The whole reason I have the water feature is for the animals that visit my yard. It's too bad the company that makes the product isn't more detailed and clear about the safety of this product. The other thing that is on the label, but not in the Amazon description, is that it is considered a "pesticide". I am still researching the exact ingredients and I would suggest anyone considering purchase do the same and then make your decision based on your findings. I will probably look for a more natural alternative to this product our of concern for animals, but it definitely does its' job on algae.

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