Growonix Replacement Carbon Filter (Green Block) - 2.5 x 10-in - Coconut Shell Carbon

Fresh Carbon Filtration for Cleaner Feed Water - 2.5 x 10-in Block

Chlorine and other disinfectants in tap water can interfere with a clean, consistent nutrient program, and a spent carbon block stops protecting your system. This replacement block is made from coconut shell activated carbon and reduces chlorine, taste, odor and certain VOCs from incoming water. It is listed as NSF Standard 42 & 61 certified, with low pressure drop and high dirt holding capacity.

Sold each, this single block suits hobbyists and small indoor growers keeping one compatible unit running, and it is easy to stock in quantity for commercial rooms that run several systems and change cartridges on a schedule.
