HTH Spa 86116 Defoamer, Spa & Hot Tub Chemical Eliminates Foaming, Softens Water, 16 oz

Work great. I was a little skeptical at first. But after pouring a little bit in the foam stopped. It does last a while. I keep buying this because it works so well. It does last about a month before i need to add more. But i only use about a ounce at a time. Definitely worth it for foam build up

The best SPA chemicals to use on your spa. They work well. I like how it works and last a long time. It makes the water very clear. Great value for the money. Highly recommend.

In my opinion this defomer far out performs the conventional granular defomer I have been using prior. Cheaper and more effective.

It worked well had to use more than I normally do

This product works fast with very it product needed.

This is my fifth order for HTH spa deformer. I've tried other brands and other formulations, but this is the best out there. It works instantly! I just pour a cap full in the spa, with the jets running, and the foam disappears instantly. The spa water feels silky smooth. A must-have water treatment product.

Reasonably priced and works immediately. If you're like me and you wash your swim clothes weekly, the detergent that stays on them will cause bubbles in your hot tub. This product works on contact with the water and is reasonably priced making it an ease for use.

Best brand out there. We only use this at work for our tank. Keeps the water super clear
