Bio spira is a pouch of overpriced garbage that a genius marketing department has promoted to convinced people it will cycle their tank for them. I have used it twice and have read other peoples experiences with it. Trust me...save that money for your down payment on the brooklyn bridge.
As others have said move as much over from the old tank as possible. By some totes or trash cans and have SW
mixed and ready for wc
's. You may want to have some prime or similar product available if needed. Also poly filters or PURA filters will help. You can also cycle the tank before the move and seed it with some sand from existing tank.
