SpaBoss Defoamer is a concentrated, effective liquid that helps eliminate foaming in spas & hot tubs. Just use a few drops to break up excessive foam.
Foam Hint: If you are “combating” foam in spa water that is older than 3 months, the best thing to do is change the water (drain & refill). Over time, large amounts of organic impurities that are not filterable or oxidizable, must be physically removed by changing the water. Excessive foaming is a sure sign of this necessary hot tub maintenance item.
