hello everyone I need help im so confused wih all the contradicting information on the web, Grill top no grill top dimming thermostat no thermostat. my local pet shop recommends UVB bulb and Ceramic heat bulb only...that doesn't seem right. I have Brain Damage and find it very hard to understand what im supposed to do. I just need someone to say "Right Daniel this is what you need" I currently have a 3" viv but i'm looking to upgrade to a 5" x 2" x 2".
