Review on Premium Activated Carbon for Aquariums - MarineLand Diamond Media, 40-Ounce (PA0373) by Marcia Davis

Got stainless steel exhaust filter for 3x3 grow tent. Remove the filters, three screws at the top and bottom, and remove the old activated carbon (the product has the same activated carbon size as the old activated carbon in the filter). Filter with new carbon, put in a mesh bag, screw back in and WALLA. Completely new! I think this charcoal worked better than the filter that was originally included! ABSOLUTELY ZERO ODOR and has been going strong for over a month when my plant flowers. Don't waste money on an expensive suitcase by throwing it away, just do it yourself and the same big bucks!
