Yup That Stuff
i use the Marineland® Visi-Therm® Stealth and you can get them at petsmart...they are plastic and have worked great for my tank, i have 2 of them in there...if you are goin to get them i would suggest look at them online ant petsmart.com and printed out there on line price for which wattage one you want and they will match it in store....
