Hydor Inline Heater 200W

The Hydor Inline Heater 200W mounts externally in the return line of canister or sump filters using standard 16/22mm tubing, completely eliminating visible heater hardware from the display aquarium. Water flows through the heater body on its return path from the filter, where it is heated to the precise set temperature before re-entering the tank. This design reduces clutter inside the aquarium and eliminates the risk of fish burns from direct heater contact. An adjustable thermostat dial provides accurate temperature control from 20°C to 30°C, suitable for most tropical species. Compatible with freshwater and marine systems, it is the preferred heating method for serious aquascapers.
