Canadian Spa Spa Ball & Cleaning Pad For Hot Tubs, Spas And Pools

The Spa Ball sits in the hot tub or pool filter box and acts like a sponge to absorb oil and other residues from the water surface to help you achieve crystal clear water. When new, the Spa Ball will float on the water surface. As it absorbs oils, greases and other surface residues it will sink, indicating that it should be replaced. The Spa Ball also helps to reduce foam build up and spa odours.
