I am draining and selling my 210g this week end. The replacement tank is going to require a little prep before I can fill it so I will be moving fish to a spare tank. The spare is to small for all the sand I will be removing(200#). I dont want the BB in the sand to die. Any suggestions? Also, if I take the media out of the sump and put it into the tank with the fish, it should be ok right? Any thoughts?
