    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.

    400w model is rated for aquariums up to 105 gallons.

    No complaints so far. 10/29/2014

    I have a 55 gal tank in a unheated basement. The ambient temperature swings from 60 to 70F. This heater holds temperature within a few degrees. This replaces 2x200W heaters which did not hold near as tight. The verdict may still be out as I only had the heater a couple weeks.

    This is not the first HYDOR product I bought and just as the first, these heaters are crap. I have a 150 gal reef, 400watt is 100 more than heater it replaces and my temp swings from 73 degrees to 78. It cant even handle the room temp variations from when I go to work in the morning to evening. When room warms the tank warms too much. 

    Good heater 12/20/2013

    I have a 92 gal tank my room temp is 68, the heater keeps a constant temp of 78. So far I'm very happy with it.
