For heat, I have a 75W turtle tuff halogen lamp 12" above his basking area. Is this a good distance?
For UVB, this is where I'm having troubles. Does it matter how far/close it is to the basking dock? It's hard to explain, but the way I have it set up there are two ledges that I can clamp on to. There is one that is 13" above basking dock, and there is one that is really close at 8". Is this too close? I have reptiglo 5.0 26W bulb.
How do you guys have your bulbs setup? I find the reptile clamp lamps difficult because I can't adjust their distance when I clamp them to the tank.
Also, is the UVB harmful to my eyes? The bottom half of it is poking out of the bottom of the lamp and I can always see it.
