say i had a 2.5 g fuge, and it is in my tank that has fish in it and is cycled and everything. now, im going to take out the fuge and put in a new fuge. can i just put the old sand strait into the new one and put it back in my sump? will this cause a cycle? i need quick replies! i have work soon and wanna do it before work! thanks!
