The AquaFX Refillable Cartridge is an empty filter housing designed for use in standard 10-inch reverse osmosis deionization systems. This versatile cartridge allows aquarium hobbyists to create custom filtration stages by filling it with their preferred bulk filter media. It provides a cost-effective and environmentally friendly alternative to disposable, pre-filled cartridges by enabling you to purchase media in larger quantities and refill the shell as needed.

This durable cartridge measures 10 inches by 2 inches, a standard size compatible with most residential RO/DI units. It is designed for easy opening and secure closing, ensuring a reliable seal while making media replacement a simple task. The shell is suitable for a variety of media types, including Granular Activated Carbon (GAC), specialized Chloramine Blaster Carbon, and color-changing or standard Deionization (DI) resin, offering maximum flexibility for your water purification setup.

This product is ideal for the hands-on reef aquarist looking to optimize their water purification process and reduce long-term costs. If you frequently replace DI resin or carbon stages and want to save money by purchasing media in bulk, this refillable cartridge is the perfect solution. It empowers you to take full control over your filtration, ensuring the highest quality water for your saltwater aquarium while minimizing waste and expense.
