HIGH GC, I have a Stanley blower, which will recirculate my air and cool my light. Question is, what size filter do i need for that fan? My room is roughly 2"x4"x6" and as I have read, the fan puts out roughly 300cfm. So what size does my filter need to be and where can I get "AIR" carbon, as opposed to the aquarium carbon stuff? Locally that is... Thanks in advance.
roughly 2.5 inch od carbon / side wall, and 24" long should suffice.. I'm building one to use a special kitty litter instead of loads of expensive carbon.
