The 10W model HG-031 is built for glass or acrylic aquariums of 1 to 5 gallons, including nano and betta tanks, and it works in freshwater and marine water alike. Its external temperature controller lets you set the heat without putting a hand in the water.\u003c\/p\u003e\u003ch2\u003eSetting the temperature and reading the display\u003c\/h2\u003e\u003cp\u003eThe heater covers a range of 59–93°F. The controller carries an LED digital display that shows the current water temperature as it changes, and the dial sits on the controller outside the tank, so adjustments happen away from the water.\u003c\/p\u003e\u003cp\u003eTwo error codes appear on the controller when something needs attention: HH when the water is too hot and E1 when the heater is out of water. Heating stops on its own once the water passes 95°F, and it also stops when the water level drops below the minimum line. Unplug the power before cleaning the tank or changing water.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eHG-031\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColour\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget audience\u003c\/th\u003e\n\u003ctd\u003efish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e10W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eQuartz Glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e3 x 3 x 10.5 cm (1.2 x 1.2 x 4.1 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem weight\u003c\/th\u003e\n\u003ctd\u003e270 g (9.5 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecial features\u003c\/th\u003e\n\u003ctd\u003eAdjustable, Automatic, Easy to Use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eDoes this heater fit your tank?\u003c\/h2\u003e\u003cp\u003eThe 10W rating is the one to compare against the size chart, and the chart is what decides whether 10W is the right choice for your setup.
