Doesn’t work

I purchased this at Lowes for my spa. It had a bit of dust on it so it might be a bit old. But it doesn’t work at all. I have used Clorox Spa Shocker and it seemed to work after I had to put in more than directed. I don’t think I will be buying anymore Clorox Spa products.

Definitely recommended

Anti foam is great! This is our second spa (had to leave our other spa behind when our House was sold) but would not be without this product or any of the Clorox chemicals.

Instant Results

Occasionally our hot tub water developed foam. When Clorox Spa Antifoam is added, which is always just one teaspoonful (one cap full), all foam present on the water’s surface instantly disappears.
