Take the actual filter cartridge with the gunk on it, and place it in your new filter behind the new cartridge.(there's a spot for that isn't there?) If it doesn't all fit, put the bio sponge right in the tank and squeeze it out over your bio wheel from Time to time. any sludge at the bottom of the old filter could be poured into the new one.
