I just bought some Marine Labs Black Diamond premium activated carbon and didnt know if this was ok to use for my tank. I have never used carbon until I got my nanocube for christmas and it has been a little over a month since it has been set up... so I guess its time to change carbon. I bought the reusable bags for carbon and this. I figured I'd ask before actaully using it if this was ok or if another brand is better?
