This 10-inch clear filter housing is a crucial component for any saltwater aquarium's reverse osmosis deionization (RO/DI) system. It is designed to hold a standard 10-inch filter cartridge, serving as a pre-filter or post-filter stage to remove sediment, chlorine, and other impurities from your source water. The clear sump allows for easy visual inspection of the filter cartridge, so you know exactly when it's time for a replacement, ensuring your system always produces the purest possible water for your reef tank.

This unit features a durable, clear sump body and a black ribbed cap that provides a secure, leak-free seal while being easy to grip for cartridge changes. It comes equipped with standard 1/4-inch female NPT inlet and outlet ports, making it compatible with most RO/DI tubing and setups. A built-in pressure relief button on the cap allows you to release pressure before opening, simplifying the filter replacement process. The housing is designed to fit most 2.5-inch diameter cartridges, including common 9 7/8-inch and 10-inch sizes.

This filter housing is ideal for both new DIY RO/DI system builds and as a direct replacement for a cracked, leaking, or opaque housing on an existing unit. Hobbyists who value convenience and proactive maintenance will appreciate the clear design for monitoring filter life at a glance. Its universal sizing and standard port connections make it a versatile and reliable choice for any aquarist dedicated to maintaining pristine water quality for their sensitive coral and fish.
