A new tank is too sterile to support robust bacterial growth. They need "carbon" and don't care where they get it. Sometimes you hear of people adding liquor (ethanol) to a new tank for cycling. The ethanol is used by the bacteria as a carbon source. Don't get carried away with the sugar or your water will become cloudy.
what about just using carbon? i have a few socks full of carbon kicking around in my stand .. any good to use them and if so where? in sthe w/d?
