I have a 10g tank with a Penguine 100 Bio Wheel filter and I will needing to replace it before too long the problem is there is not enough room to put another filter in while it accumlates BB.
My question is could I put the new filter in place then leave the old filter in the tank, or vise versa leave old filter in place and set new in the tank?
