Rust Grabber

Before you fill or top off your swimming pool and hot tub-thread a Rust Grabber on the end of your garden hose first! The Rust Grabber acts like a pre-filter, helping remove iron and other minerals before they enter your pool and spa! It helps remove iron, copper, lead, lime, zinc and more! Rust Grabber gets dirty from the inside out and is reusable. Depending on the hardness of your water and how many gallons you are filling, Rust Grabber is good for reuse until the outside of the fibers are dirty or stained-looking.
