Coralife Carbon Cartridges for Marine Filter - Large - 3 pk

The large Cora life Marine Filter Replacement Cartridge pack contains three dual sided, dense floss carbon cartridges designed to remove unwanted debris and odour from the Cora life Marine Filter with Protein Skimmer. These cartridges need to be changed every 4-6 weeks or whenever you observe water beginning to enter the filter bypass or when the cartridge itself becomes clogged with various organic waste and debris. Unlike other filter cartridges, replacing this unit is speedy and hassle free.
