Fountain Algaecide and Clarifier - 64oz - Kills and Inhibits All Types of Algae Growth, Formulated for Small Ponds and Water Features, Treats up to 64,000 Gallons

Works great. Cleared up fungus on our water vase fountain. I let the product work for a couple of days then cleaned and scrubbed it out. Looks so much better and so far hasn't come back after three weeks so far.

I’m using it in combination with a little pool chlorine and I find in my fountain it works best in that combination.

Just started using this product, so far, it’s working. My pump is stay fairly clean with consistent water flow. Now the test of fall and early winter.

Very good algae cleaner!

I didn't see much of results

Works as advertised

Working great!!

For me and my two bubblers, this product did not work. Algae seemed to enjoy it, to be honest. The dosage recommendations also don’t seem to pertain to fountains, the use that’s in the picture and the product name. The dosage recommendations are for ounces per 1,000 gallons. I don’t know about everyone else, but the water in a fountain or bubbler is not measure in the thousands of gallons. Maybe that results in my using too much product and being counter-productive to killing algae? Regardless, I’m going to order a different product.
