The plastic bag won't work, not enough contact area plus the carbon will fall through. You don't need a powerfilter either. Get a <<filter sock>>
which should be available from your LFS
and a plastic berry basket from the market. Place the carbon in the bag, rinse well with RO
water and let drain. Tie the berry basket so it hangs below the outport of your skimmer. Place the cabon bag in the basket... 8)
