The Hydor Aquarium Heater ETH for external canister filter is the first and only external heater with PTC system (Positive Thermal Coefficient), which can be connected to all external filters. Maximum safety through the PTC system, which protects against overheating and burnout. The applied exclusive technology and the high quality of the components guarantee a long service life.
The Hydor Aquarium filter heater ETH for external canister filters makes a classic heating element in the aquarium superfluous. The control heater / flow heater from Hydor is simply mounted directly after the external filter in the hose, which goes from the filter back into the aquarium.
Suitable for all aquarium - exterior, lower cabinet and sump filters with hose connection 12/16 or 16/22 mm. If necessary, other hose diameters can be connected via hose reducers (e.g. from Eheim).
To set the desired temperature (between 18 and 34°C or 65 and 93°F), turn the thermostat knob until the indicator on the heating element matches the selected temperature. If the temperature in the aquarium falls below the set value, the HEATER device switches on automatically; Heating up is indicated by a function LED.
