HTH Spa Defoamer

I tend to only use this product toward the end of the water life cycle. It is a good value for the price and lasts a long time. I will continue to purchase it.

Great product. No issues at all and works right away!

Delivered on time, when added to a foaming fountain due to the addition of an algae inhibitor working great!!

It works as advertised, it eliminates foam after chlorinating my pond. I have purchased several items from Arch Chemicals and am very happy with my purchases and will continue to purchase my pond products from them!

Got this because I had foam in my hot tub. Put in an ounce and the foam was gone in about 30 seconds. The anti-foam stuff spread out over the surface of the hot tub and presto, the foam was gone. Great product.

Works great

Good product! I had to send for this as nowhere on Guam do they sell this. I should have ordered a few bottles but I wanted to try it out in my hot tub first. looks like I'll be ordering more......

Does what it is supposed to do. Keeps foam from forming in WaterFall.

Just a little bit will knock down the "sea foam" that sometimes occurs after adding chemicals & such. No residue, no odor, only a few ounces needed. Works great.

works in my water fountain....no irritating bubble foam anymore

terriblble product, made foam worse left layer of white chucky scum after several filter cycles no improvement. Needed to drain and start over, product is in garbage. Called the help line no help at all Refund would be nice

Instant results with only a few drops. Maybe the company should use that line for advertising haha. My expectations have been exceeded.

Works very well, especially with sensitive skin.

Works as advertised! A capful clears foam amazingly well. You can hear the bubbles popping and watch as the foam diminishes before your eyes.

The HTH Defoamer is important to keep handy ,add as directed to control foam build up , I have used this product for a few years now , it works good , don`t go hot tubbing without it !
