AM cycling a 75 gallong tank. Heard everyone on here say charcoal is really useless unless u r trying to get meds outta the water. Was wondering if I could take the carbon out of my AQ70 and replace with another form of bio starts, rings, bio-max etc? WOuld this assist in cycling the tank, adding good bacteria?? I am running 2 AQ70's at present.
