Scum Bug Sponge (Pack of 2)
Scum Bug - The Oil Absorbing Sponge (Includes 2 ScumBugs!)
For extra clarifying power, drop a Scum Bug in your hot tub. Using technology originally developed to clean up ocean oil spills, this floating foam collects water contaminants that create scum lines, cloudy water, and clogged filters. To use, simply float on the spa water surface. When the Scum Bug becomes saturated, simply rinse with fresh water and wring out (not in spa), to prolong the life of your Scum Bug.
