THEO Heater - 300W - Up to 80 gal.
Item # 205234 / Manufacturer Part # T11402
Provide your tank with the proper temperature with the most advanced heating technology available. THEO heaters are designed with a peculiar cylindrical shape that renders them virtually shatterproof. Fully submersible, THEO heaters function with the PTC (Positive Thermal Coefficient) heating element, a special polymer sheet silk screened with heating ink (like your car's windshield defroster), that enables them to run dry for a short time without damage. With an easy to read temperature dial, these heaters are the simplest, yet safest available.
Ideal when placed in the vertical position but can be installed in a horizontal position completely submersed.
300w model is rated for aquariums up to 80 gallons.

So far so good 3/7/2013
I have two of these in my 150 gallon. They do heat up the water but the temp gauge is off. I have it set on 71 to keep my tank at 77. When I had it at 77, my water temp was in the 80's. so it works, you just have to play with it a little to make sure the temp is where you want it.
