What if this doesn't remove the foam from my spa water?
All of our spa chemicals are professional grade and should fix foam issues assuming foam is not just a symptom of a larger underlying issue (we sound like doctors, hence the name). However, if you're not also using a water clarifier, you may still have dirt contaminants that continue causing foam. Either way, if you haven't found a solution to your hot tub foam issue, we have a 100% money back guarantee. We will get you the right hot tub chemical for the job or your money back.
How can I prevent foam so I don't have to order this every week!?
Foam is typically caused by contaminants in the water. We recommend preventing getting contaminants in your water and regular maintenance to control those contaminants before they become a problem.
To prevent contaminants that cause foam:
Avoid using fabric softener on hot tub bathing suits when washing
Remove makeup and other oils before getting in the hot tub
Try to avoid dipping hair into the tub or remove hair product before use
Regularly add spa water clarifier to your hot tub and defoamer once a week

Works, but doesn't last
he hot tub defoamer does help with foam, but it’s not a complete solution. It effectively eliminates about 70% of the foam, but as soon as you get in the water, the foam tends to return.Pros:Reduces foam: Works well at getting rid of most of the foam.Easy to use: Just a small amount does the trick, and it's quick to apply.Effective for short periods: It does provide temporary relief from excessive foam.Cons:Foam returns quickly: As soon as you get in the hot tub, the foam tends to come back.Not a long-lasting solution: Requires frequent reapplication for ongoing results.While it does help reduce foam initially, it doesn't completely solve the problem for long periods. It’s decent, but not perfect.
Really impressed
I was amazed at this product. I had phone building up in the hot tub so I bought this product and I hope it would take care of it. It certainly does right away. We’re really impressed with this and we use it on a regular basis when we start getting the foam in the hot tub.
Just ok
It’s ok. Works fast but leaves slimy white chunks of product behind. I would give it a lower score for this reason except it really does take care of the foam.
Works as should
My husband uses this in our spa and states it does what it should and he is pleased. He will purchase this again!
