I just recently moved to a temporary location and had to put my Oscar, Pleco and Gold Severum in a 20 gal from my 55 for a few weeks. I have the 55 in storage but have the Bio Wheels sitting in the 20 gal with the fish until I move again, which is in a couple of weeks. Since I don't have much water to take to my 55, how should I move them back to the 55 with out more than 11 gallons of cycled water? Any feedback is appreciated.
