Boyd Chemi-Pure Aquarium Filter Media – 10 oz is the original Chemi-Pure blend of activated carbon and ion-exchange resins. Sealed in a ready-to-use bag, it removes the dissolved waste that turns water yellow and stresses livestock, all without stripping the tank of the chemistry it needs.
Rinse the bag and set it in your filter, canister, or sump where water flows through it, then swap it out every few months. It works in freshwater, saltwater, and reef systems and pairs well with mechanical filtration like filter socks or floss.
Boyd Enterprises has manufactured Chemi-Pure in the USA since 1960 and remains a long-standing name in aquarium water care.
