Hot Tub SERUM Oil Absorbing Sponge

The sponge is made from a specialized 3D air mesh material that attracts and traps surface contaminants like body oils, lotions, and cosmetics. By soaking these up while they float on the surface, it prevents them from entering your filtration system or settling on the spa walls as a scum line.

Yes, it is fully reusable. When the sponge becomes saturated or discolored, simply rinse it out with water or wash it with a mild soap, squeeze it dry, and place it back into your spa.

The Sharky sponge is designed to be versatile and fits almost any hot tub or swim spa. At nearly 12 inches across, it is large enough to handle the surface area of a swim spa while still being compact enough to float freely in a standard hot tub.

While it doesn't replace the need for regular filter maintenance, it significantly reduces the workload on your filtration system. By capturing oils and debris before they reach the filter, you will likely find that your filter stays cleaner for longer periods.

Because the material is durable and washable, you don't need to replace it on a strict schedule. You should replace it once the material begins to degrade, loses its shape, or no longer effectively absorbs oils after a thorough washing.
