Wher would I put the carbon and what would I put it in? I
The carbon simply needs to be in a high flow area. You can put it in a media bag which can be purchased at the LFS
. Some people use pantyhose or cheese cloth as well, but for the price of the media bag (~$2) I just buy those.
My carbon sits right under the output of my overflow in the bottom of my sump. That way every bit of water that passes through the tank, at some point, comes in contact with the carbon. You will need to determine the best place to put the carbon.
As for the micron bag would it still work if it was completely submerged in water where my overflow enters my Aquafuge?
I have found that filters tend to work better when water is being drawn into them rather than being pushed through them (make sense?). In other words, you could try to put the micron sock over the overflow inlet so as water goes into the overflow, it passes through the sock.
I still think you are better with GAC
