The AquaFX Add-A-Canister with Refillable Cartridge 10x2 is an essential accessory designed to expand and enhance your existing RO/DI (Reverse Osmosis/Deionization) water filtration system. This versatile unit allows you to introduce an additional stage of filtration, providing extra capacity for various media to further refine your aquarium's water quality before it enters your reef tank.

This kit includes a durable 10" x 2.5" canister equipped with standard 1/4" fittings for easy integration into most RO/DI setups, along with a convenient refillable shell that can be filled with your choice of media. For straightforward installation, a mounting bracket and 6 feet of 1/4" RO tubing are also provided. The refillable shell offers unparalleled flexibility, allowing you to utilize specialized carbon, softening resins, additional DI resin, or other custom media to target specific water impurities.

This product is ideal for saltwater aquarium enthusiasts looking to optimize their water purification process, extend the lifespan of their RO membrane, or address unique water parameters. By adding an extra stage, hobbyists can ensure even purer water for their sensitive reef inhabitants, protect their primary RO/DI system components, and maintain a healthier, more stable aquarium environment.
