Hello all, I am so confused about where to put the UVB light fixture in our tank. It seems like there is so much contradictory info out there. I am second guessing how I should have it. We have a standard 40 gallon tank with a screened top. I just got the Reptisun T5 HO 24” hood. Do I leave it on top of the mesh or mount it inside? And depending on where it should be placed, should I use the 5.0 or 10.0 bulb? Our Beardie loves hanging out on her hammock, so I need to be sure she is far enough away from the UVB. I usually read it should be 8” away from where she lays, is this correct? Any clarification is appreciated. Here is a photo of the set up. TIA!
