High-purity bituminous carbon pulls dissolved organics, medication residues, tannins, and odors out of the water column, polishing the tank to crystal clarity in freshwater or saltwater systems.

As water passes through the pouch, dissolved organic molecules adsorb (stick) to the carbon surface, removing the compounds that cause yellowing, odors, and chemical haze. It is the standard polishing step after a medication cycle, pulling residual treatments out of the water before you return to normal husbandry.\u003c\/p\u003e\n  \u003cp\u003eNote that activated carbon does \u003cem\u003enot\u003c\/em\u003e remove ammonia, nitrite, or nitrate.
