This specific Horizon Scumball comes in 2 twin packs and is made to be efficient in the collection of all the dirt from oil, scum, lotion, and makeup residues that ride on top of your hot tub, spa, or swimming pool after a heavy bath.
The oily and scum residues that collect in your hot tub are very dangerous since they will clog your filter cartridges, shortening the life span of your hot tub filters.
To remove oil, scum, and lotion residue from your spa water, drop a few scumballs in the skimmer of your hot tub and drop some more in your water to float and collect all the oily and scum residue riding on top of your hot tub water.
Scumballs remove all the scum, preventing nasty scum-line that appears in your spa after a heavy bath. Fluffy tennis balls can also do the trick if you can't get Scumball for some reason.
