About this product
This 100W aquarium heater suits 12-30 gallon freshwater and saltwater tanks, and its body measures 8.8 inches long. The adjustable dial covers 68 to 93 °F, and a built-in thermostat switches the element on or off as the water temperature moves. The heater is made of 2 mm quartz glass and comes with a sticker thermometer plus three suction cups.
Heater build and temperature control
The 2 mm quartz glass wall is 33% thicker than the 1.5 mm glass used on normal fish tank heaters, and the manufacturer describes it as more resistant to cracking and corrosion. A built-in thermostat holds the water at the temperature you set within a ±2 °F error.
The heater turns itself on or off as the water temperature changes, so the set point is maintained by the unit rather than by hand. Turning the dial sets any temperature between 68 and 93 °F.

Does this heater suit your tank?
Check the tank volume first: this 100W unit is rated for 12 to 30 gallon aquariums, in fresh or salt water. Measure the space where the heater will sit, because the body is 8.8 inches long and 1 inch across. The cord reaches 5 ft from the heater to the outlet, and the water level has to cover the whole body at all times while the unit runs.
