bought my tubs sterilite 105q /99l , bought UTH's (reptitherm 50-60gallon sized 25w), and plugging them into my reptitherm 500r thermostats....

I know everyone here says the uth is safe on the tub, but the safety thingy on the pads say strictly not for plastic or acrylic plastic, nothing other than glass....

is that basically just a "just in case, we told you so" warning....

just want to make absolutely sure i dont start a fire or melt the tubs or burn teh balls.
