Has anyone had any experience with using a waterbed heater taped/attached to the side of your fish tanks? I saw something on the YouTube about someone using one once, but now I can't seem to find the video, or it was removed (watching YT at work... bad idea... ).

I have a small-ish basement setup with a 150 gallon Rubbermaid stock tank as my fish tank. The same kind of tank I use to water my horses, but, we have an element style floating heater in the horse tanks, and the Rubbermaid holds up just fine.

Just wondering...
