The Aquatic Life 5 Micron Solid Carbon Block Cartridge is a vital replacement component for reverse osmosis systems, designed to purify tap water for safe aquarium use. Its primary function is to effectively remove harmful chlorine and chloramines, which are toxic to fish and invertebrates. By using this activated carbon filter, aquarists can ensure the foundation of their saltwater mix or top-off water is free from common municipal water treatment chemicals, protecting the delicate inhabitants of their reef ecosystem.

This standard 9 3/4" cartridge is engineered for performance and compatibility, fitting all AquaticLife RO units and many other standard residential systems. It features dual rubber gaskets to guarantee a perfect seal, ensuring 100% of the water flows through the carbon block for maximum contaminant removal. A durable outer and core wrap secures the solid carbon block, maintaining its integrity and effectiveness for up to six months of typical use before a replacement is needed.

This carbon block cartridge is an essential purchase for any saltwater or reef aquarium hobbyist who uses a reverse osmosis system to produce purified water. It is especially critical for those maintaining sensitive corals and fish that require pristine water conditions. Regularly replacing your carbon block is a fundamental step in routine filter maintenance, ensuring your RO system continues to produce high-quality, contaminant-free water for water changes and evaporation top-offs, promoting a stable and healthy aquatic environment.
