Hot Tub Foam Eliminator, 2 Pack Pool & Spa Defoamer (32oz/ Bottles) – Eliminate Foam Without Harsh Hot Tub Chemicals, Eco-Friendly & Safe w/Silicone Anti Foam. Get Foam Down and Enjoy Leisure Time

Works quickly and does a good job, I’ve also tried other defoamers and it works about the same as the other ones, you can use it for a while before you have to put in new, we use it on a seven person hot tub. It works immediately.

We have a larger 1400 gallon hot tub that gets a ton of use due to Airbnb'ing our guesthouse. Let's be honest, Airbnb guests will test the limits of your tub and chems. With just a quick squeeze, this stuff works great and within seconds to get rid of all the suds from lotions and detergents and sun screens, etc.

Great value but not quite as good as my spaguard. I always have to use more than I think but considering how great the value is it’s not a problem. No issues with my hot tub and no off putting smell. Does what it’s supposed to and that works for me

I’ve been having some issues with foaming when the jets are on high in our hot tub. Tonight, I turned on the tub and waited for a minute for the foam to get pretty thick, added just over half an ounce of the product (350 gallon tub), and the foam disappeared in less than 20 seconds. It was really amazing how fast this stuff circulated through the tub and basically completely removed all of the foam. When I turned the jets off and gave the water time to settle, I was happy to see that the water was just as clear as always. Those who are complaining about cloudy water likely added too much, or have other issues with their water chemistry. A very little bit goes a long way. I’d recommend measuring, as it’s probably easy to add too much if you just squirt it in. Also, give it some time to work before adding more.The price is also much better than some of the more well known brands, and it’s probably going to take me quite a while to go through two large bottles of this stuff!

Works well

Does great keeping hot tub from foaming. Will order again

This is a great value for the money. I have tried other brands and this works the best for quite a bit less money. It last quite a while as well. Just buy it already!

I was under the impression that this product was going to get rid of the majority of the foam in our recently purchased hot tub. It helped, but I had to use far more than the bottle said, that said our hot tub is saltwater and I’m not sure that it doesn’t have a different outcome. I looked all over Amazon and there really wasn’t anything in the question or reviews that gave a definitive answer. I am going to look further before I purchase anything else.
