Horizon HV-SB2PK Scumball Pool and Spa Scum Eliminating Ball (4 Packs of 2)

The washable and reusable Scum Ball absorbs oils, dirt, and contaminants present in the water, and is very easy to use. Just place the Scumball into your pool or hot tub and enjoy sparkling clean water at all times. There will be no more need to get on your hands and knees to scrub the scum-line off the liner of your pool or spa. The Scumball from Horizon is the original USA Patented foam product that has been sold in the pool and spa industry for over 20 years while others are simply just a sponge. The original Scumballs only come in packaging with the Horizon logo and patent number on them. You will notice knockoffs turn a yellowish brown either prior to putting in the pool or within a short period of time in the water. The Scumball only changes color when it has eliminated foam and scum lines. It can absorbs 40 times its weight in oils and lotions and is reusable. The Scumball works in both pools and spas of all sizes. The scumball can be easily hidden in the skimmer so kids will not play around and squeeze the scum back into the pool.
