These Titanium heating tubes are practically indestructible. You need a heat controller to adjust the temperature. Suitable for Salt or Freshwater. If you have valuable fish, then these are a great choice. These are for glass tanks only. Do not use in acrylic tanks. They have a titanium element and double heating tube. The 3-prong cord requires a 3-prong heat controller (D-1500).
