Best tape to attach an Ultratherm UTH?

[instinct27]

I have one of THESE. I've been using duct tape and it just isn't cutting it. I've had to reapply tape almost weekly.

I am attaching to a glass tank just FYI.

aluminum foil tape or gorilla tape should work

aluminum tape works great, its the stuff they use on heater ducts so thats why its the only stuff that really holds up.
