so I recently got about 12' of heat tape, I have put it all together and also got a thermostat to run it. I wrapped it around my 4' glass tank, and turned it on. The problem is it doesn't really get hot enough, it is warm to the touch but doesn't warm anything up. I even took it off the thermostat and plugged it right into the outlet and it put out the same heat. I have the 3" wide one.

so I guess my question is should it just be used in the rack system? maybe this tape is just too small to put out the heat I need, yet it also doesn't seem like it would put out enough for the rack system. what size heat tape is everyone else using?

I too am trying to move away from using lights, so any info would be great
