I was at a pet store today and the representative stated that I could take my existing bio-wheel and move it over to a brand new tank just start the cycle faster. I currently have a 55 gallon tank that I know the bio wheel will fit a 30 gallon tank, but I'm not sure how accurate this representative is. My question is, what would you guys do? would you move a pre-existing bio-wheel from a running tank and move it to a brand new tank? What you move existing water from one tank into a brand new tank? Or simply do a complete new tank new water new biofilter?
