Scumbugs

Scumbugs are made of a unique patented material that can absorb up to 32 times their weight in oil. They greatly reduce the "ring around the spa" that occurs at the water line and also save your filter from becoming coated with these oils...greatly expanding the filter's effective life span. Scumbugs are constantly at work in your hot tub as they float on the surface of your spa water to remove any oils that accumulate on the surface of the water.
