SpaGuard Antifoam Concentrate is an effective and fast defoamer and foam preventer for hot tub water.
Antifoam Concentrate tightens the surface tension of the water, making it harder for foam to form on the surface
Use one capful (10ml) at a time. The amount needed will depend on the nature and quantity of foam present
Pro Tip: Adding Antifoam Concentrate will temporarily mask foam. It will not treat the cause of the foam. Most causes of excessive foam can be treated by shocking the water and cleaning or replacing the filter.
