It's being hooked up to a Hydrofarm thermostat...Now that I think about about it, I hate for it to be attached to it permanantly. Seems like that could be annoying when cleaning, or if i decide I want to use it on a different tub. I wonder if maybe I could stick the mat to a piece of Heavy Duty aluminum foil the same dimensions as the mat then just sit the tub on the mat. You think that would work?
