Ran a repti glo 10.0 for the snapper for a while and it was time to replace it. So I got a Reptile UVB200 from exo terra. Good choice or not? The light sits about 8" above the water, and the turtle has a rock under neath it that he likes to sit and bask (150watt halogen) and the rock is another 4-5" under the water. Which would put the turtle pending how he sits, 1-5" under water.
