Scumbug is insatiable! When placed in a clear pool or spa, it eliminates the formation of scumlines. Capable of absorbing up to 40 times its weight in body oils and lotions, Scumbug provides 300% more surface area than the ball and will not get clogged in water lines. When saturated, simply squeeze out, clean and reuse. Under normal conditions Scumbug should last an average season.
