Spa Defoamer is an exclusive formula that breaks up existing foam in spas, hot tubs, and whirlpools. Use Spa Defoamer whenever troublesome, unsightly foam develops.

To Eliminate Foaming: Shake well and dispense approximately one capful of Spa Defoamer onto the surface of the water while the water is being circulated. Wait 30 minutes and repeat treatment if foam has not subsided.

Note: If more than three capfuls of Spa Defoamer have been used within a 24 hour period, it is recommended that you clean your filter(s) to prevent clogging with Filter Cleaner and test your water chemistry.

    It works!!!!! Had a problem with the hot tub foaming and nothing seemed to cure the problem. 1 application of Spa Defoamer cured the problem.

    Just started using this hot tub defoamer, it seems to reduce spa foam to a acceptable level. Will consider ordering again when needed.
