help sticking flexwatt tape

What do you guys use to tape flex watt to the bottom of a tank? I am trying to use duck tape on my display tank and it is not working. After a few hours it falls off. The bottom of the tank is melamine. Any suggestions on what to use?

use foil tape or heat tape you can find it at any home depot or lowes or hardware store

i used high temp duck tape but i dont even think you would need high temp stuff. but it may leave some junk on there when you try to take it off.
