Scumbug devours Scum, Slime & Grime from pools and hot tubs. When placed in a clear hot tub or pool, Scumbug will eliminate 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. Improves filtration and extends filter life!
