Aaron, thank you so much for this thread! Right now, I have two BPs, each in a separate 40 gallon glass tank. However, I am seriously considering ditching the glass tanks for one T8 with a divider. The room temperature where the T8 will be located will be 68-72 during the winter and 78-82 during the summer. My question for you (and anybody else who has experience with the T8) is this: If I use RHPs (one for each side), will I still need Flexwatt or some other type of UTH? If you think I will need Flexwatt with the RHPs, would I be able to use Flexwatt without RHP?
