Hey Yesum. Here's some data on the carbon you want: Activated Charcoal We’re looking for 4x8 vapor phase Coconut. Carbon Activated Corp sells 55 lbs, 2 cu. Ft. for $95 + $45 for UPS www.carbonactivatedcorp.com Buy Activated Charcoal is a lot more. TIGG is also a lot more. That is one BIG bag of carbon. Keep in bag and it's good for years and years. Hope that helps!
