I'm sorry I can't help you out with your question. I just bought my UTH and was at Lowe's looking for Foil Tape today and he suggested Velcro strips. I couldn't tell if he knew what he was talking about or not so I by passed that idea.

I did want to make sure that I bought the right tape though. The package says "Aluminum Foil Tape". Is that the right stuff???

Also, if it is correct, then do I simply peel off the paper on the UTH and stick the tape on it (covering the sticky side)? Then attach it to the bottom of my tank? Is it supposed to go on the warm side?
