SpaGuard Natural Spa Enzyme - 1 qt

Love this product line. It's the only one I use!

Whether due to bad batch or general quality control issues, we have had multiple bottles of the Spa Perfect product develop black mold/mildew in them while nearly 3/4ths of the product remained unused. Once is a fluke, but after 3 times, I began looking for a different brand of enzyme product for our Softub. This one did the job nicely, eliminating the sort of "hot pond" funky smell that would sometimes develop and kept the water sparkly and no feel of chemical residue or irritation and seems to lessen the necessary amount of sanitizer used to maintain it. The liquid in the bottle was as clear when it was emptied as it was when it was opened, never clouded nor developed gobs of slimy fungus, nor did it increase foam in the water after adding... Will be using this from now on instead as I get to use the whole amount I pay for.

Very fast delivery.

Cleared up haziness with 2 applications, I thought I was going to have to drain the tub but this worked great

Effectively clarifies spa water. I have used this for many years. A little expensive but it works.
