So, for our heat mats, I like to cover the sticky portion with 1 layer of tin foil & just tape the heat mats to the bottom of the snake tubs instead of applying them directly. This makes it far easier to take the heat mat off when I need to wash all the tubs.

HOWEVER, I am having one hell of a time keeping the damn things on lately! It's driving me bonkers.

Currently I've taped strips of duct tape on them to keep them up, but even that has only lasted a few days before it starts peeling and falling. ISN'T DUCT TAPE SUPPOSED TO FIX EVERYTHING?! Any tips or tricks?!
