What would be the proper bulb for full grown Stinkpot turtles - a Zoomed Reptisun 5.0 or 10.0 fluorescent bulb. I am upgrading my two Stinkpot's enclosure and need to buy a new bulb. I have been using the 5.0 since they were babies, however, their new enclosure is much taller and so they will be further away from the bulb.
