So my puffer tank will get stinky on occasion due to his diet of raw seafood. I do regular water changes and have a great maintenance schedule but feel I need to add some carbon to help with the occasional burst of smell. The one choice would be to just add a bag of carbon to the AC110 filter or I was thinking of adding a second filter like a Penguin 200 and then use one of the refillable media cartridges full of carbon inside. Really leaning toward the second filter but would like to hear if any other things could work.... Would like to keep it under $50 and have it be an easy to fill, change out the carbon.
