5x Oil Absorbing Sponge for Bathtub and Pool, Spa Foam Octopus. Note: This product page only sells the Octopus color. If you need other sizes/colors, please refer to Questions and Answers. Description: Safe: The floating sponge on the water's surface is easy for you to see, preventing slips. Easy to Use: Throw the spa sponge in and let the filter pump run for a while, then let it float freely (turn it over occasionally). Super Absorbent: The T-Box oil-absorbing sponge absorbs non-living foam, suntan lotion, body oils, cosmetics, pollen, etc., without absorbing water. Hot Tub Maintenance Kit: By keeping foam and non-living oils away from the filter, you can maximize the filter's lifespan and minimize maintenance costs. It helps remove non-living debris that builds up in hot tubs, jet baths, and spas. Specification: Material: Straw-type cellulose. Color: White.
