Under Tank Heater

I have a UTH on my tank is there anyway I can use the same one on another tank??? I mean like taking it off and like pasting it on the bottom of the other tank
Thanks

Assuming you mean the stick on type by ZooMed, Nature's Heat, etc - depending on how easily it can be removed, it can be reused WITH CARE. The heating wires inside can be damaged in removal, and 2 problems are frequently noted.
1) It doesn't work or dies shortly after being put back into use
2) It develops hot spots or runs hotter. longevity is likely to be decreased.
I, personally, have reused them only as a bridge while waiting for replacement equipment. Most of the UTHs I purchased back in the day were not applied directly to the tank, but to a piece of foil or cardboard. Applied to tank with America's favorite problem solver - duct tape - and removed as needed/desired. Depending on your setup, you can purchase a piece of FlexWatt (even prewired) for less and run it off the same controller you currently use.

That's a great idea!
