Finnex TH Deluxe Titanium Heating Element with Plastic Guard



Titanium heating tubes are virtually unbreakable, and corrosion resistant allowing the use in salt or freshwater aquariums. The titanium housing will resist damage a traditional heater would normally encounter while also providing another level of protection with the use of a plastic guard which helps keep other pieces of equipment and livestock from coming in direct contact with the heating tube.

The Finnex TH series of heating tubes do not come with any type of temperature control. We suggest an external heater controller like the Finnex HC-820M or Finnex HC-810M for saltwater systems, or the InkBird WiFi Controller for all systems. Any temperature control device will work, the heaters only require a grounded outlet to plug into.
