Sorry, I should have mentioned that I am wanting to do my own enclosure out of wood. Thinking of going with a melamine matierial. If it works out, it will actually be two tanks (one stacked on the other). Im wondering how flewatt for the top enclosure would affect the bottom one if I mount the flexwatt outside and underneath? I got this idea from an article I read online...since I have dealt with Flexwatt before I just want to know how it works for you all...also can someone elxplain how to run a rheostat and thermometer to it? Or would I even need both? Thanks.
