The media from the turtle tank will certainly help.
Get at least an ammonia and a nitrite test kit. Add the ammonia as per all the fishless cycling articles. Watch the levels. When both the ammonia and nitrite tests read zero, do a big water change and the tank is ready.
The turtle tank media will bring in some beneficial bacteria so you won't be waiting as long as if you were starting with a completely barren tank.
