The most common cause of foaming in hot tubs and spas is the reaction of body oils and cosmetic residues with the natural alkalinity of the water
This No Foam / Spa Foamaway has been specially designed for Spas and Hot tubs to control and prevent foaming
This is to counteract the type of foam which remains on the surface of your spa water after the jets have been turned off, i.e. it doesn't quickly dissipate when the jets/blower are turned off
To use you simply add to your water when the pumps are turned on
