Serum Watercare Hot Tub & Swim Spa Oil Absorbing Sponge

The sponge is designed to float on the water's surface, where it acts as a magnet for surface contaminants like body oils, lotions, cosmetics, and dead skin cells. By absorbing these substances before they can circulate through your plumbing, it prevents the buildup of scum lines and helps your filter run more efficiently.

Yes, the Flipper Dolphin is designed specifically for the chemical environment of hot tubs and swim spas. The 3D air mesh material is durable enough to withstand standard sanitizers without degrading prematurely.

Because it features a washable 3D air mesh skin, you can simply rinse it off or gently hand-wash it with mild soap when it becomes saturated. Once it is clean and dry, it is ready to be placed back into your spa.

While it is nearly 12 inches across, the sponge is flexible and designed to float freely, so it won't obstruct your jets or seating area. It is sized to provide maximum surface area for absorption, making it effective for both compact hot tubs and larger swim spas.

The sponge is reusable and comes with a 3-year warranty, so it is built for longevity. You will know it is time to replace it when the material no longer effectively absorbs oils or if the mesh begins to show signs of wear despite regular cleaning.
