Why is our hot tub defoamer so awesome?

AquaDoc's spa clarifier attracts micro dirt particles together, almost like a magnet, so that they can be caught by the hot tub filter. This clarifies your hot tub and extends your spa filter cartridge lifespan.

How to remove spa foam with our defoamer

  1. Add 1 - 3oz of defoamer to the foamy hot tub water. 
  2. Circulate the hot tub antifoam for at least 5 minutes. 
  3. Repeat this spa foam treatment process weekly as needed to keep the hot tub foam down. Ensure filter cartridge is clean before use.

Frequently asked questions about our Anti-foam

Q: What if this doesn't remove the foam from my spa water?
A: All of our spa chemicals are professional grade and should fix foam issue 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.

Q: How can I prevent foam so I don't have to order this every week!?
A: 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
