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 carís
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.
Place in the heater in the aquarium in an area with good water circulation.
In order to set the heater, turn the knob on top of the heater, until the
temperature indicator corresponds to the required temperature.
This heater is highly accurate due to the use of precise micro-switch
technology. For saltwater or freshwater aquariums. UL listed; 6' power cord;
shatterproof glass which, while not unbreakable, is designed to resist breakage
