Ok i just went out and bought all the stuff i need, tank, heater, water dish. I have a two part question. 1, is it safe to use an UTH with a rather thin substrate like newspaper, or do i definitely need real stuff like aspen? (was tryin to save a little money), and secondly, do i really need to use the little tank feet the heater comes with, and use the adhesive backing also? I have a styrofoam lid thing I planned on putting the UTH on, then tank on top of that, to protect my bookshelf top. Can i do that and just have the tank resting on top of the heater? or do i absolutely need to use the feet to lift it up a little and adhere the uth to the tank? can i use my own tape on the 4 corners so it can be removed later? i did get a 15 gal tank so its gonna be with me for a long time yet. should i just go ahead and permanently attach it? Thanks for helping a newb out
