No problem.

I'd have to agree on verifying the temps on the tape. I'm an engineer, so I have an understanding of thermal gradients as well as insulated/ non-insulated heat. The temps via the tape to the tub should be lower than the tubs surface temps as it's a thicker material that will hold heat longer. The tape is attached to melamine with aluminum tape so the surface acts as a large heat sink when the thermostat turns the power off once the surface temps of the tape hit the designated temps. I can understand the 90 degree point (non-insulated) and the 98.6 insulated (as the tub probe is between the plastic tub and the substrate.) I'll need to get a IR thermometer to verify the temps on the substrate.

I'll post up any updates. I hope I can get this figured out this week as I plan to have a yellow belly (possible cross) and a lesser in them by Saturday.
