The Scumbug is insatiable! It devours scum, slime, and grime from pools and spas. When placed in a clean pool or spa, it also 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 competitive products 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.
