    • Just a spoonful works like magic!
LOVE this for my hot tubs! Literally just a spoonful goes in....and like magic....you see and hear it work! Poof...no more foam! It also makes the water really soft.

    • Amazing
It only takes a tiny amount to eliminate all foam in my hot tub. Works instantly as well. I found out later it's much better to use non-chlorine shock (oxidizing type) to keep the water clean (and crystal clear), and you won't get foam, but still nice to have on hand.

    • Clears up foam within seconds
I bought this product because my hot tub had a lot of foam swirling around the middle. After reading the reviews, I decided to give it a try because HtH is a very reputable company. I tried it, and within seconds the foam had dissipated. I literally was amazed. I did not expect it to work so quickly. This stuff is great! I will definitely be buying more of this stuff, and I highly recommend it if you have foam in your hot tub. All you do is turn on the jets, wait for the water to foam, and then pour about an ounce in the foam, and within seconds it is gone. AMAZING STUFF! ... show more
