Any and all advice greatly appreciated.
Add some media from the filter in the old tank to the filter in the new tank. You might also add a little of the gravel from the old tank to the new tank. This will help give the cycling process a little boost. Fill the tank with fresh conditioned water and add the bacteria starter. Adding water from the old tank won't really do anything for you. After that, approach the cycle according to whether you want to do a fishless or fish in method.
