## Description

The Cobalt Aquatics ACCU-Therm fully submersible heaters feature an easy to set thermostat with and ON/OFF indicator light that is Triac equipped that turns the heater on and off at lower voltage, and magnetic contacts that ensure positive contact and release of the thermostat switch every time. All of these features are have been engineered to extend life and reliability of the thermostat and ultimately the heater. The tube is made of Borosilicate glass for superior heat and shock resistance and surrounds a high quality ceramic heat radiator that provides even and the best heat distribution from the heating elements. Perfect for freshwater and saltwater aquariums. Accurate to ±2°. Available in 25 - 300 watt sizes.

Review: Garbage - Not even a week old I hear a loud bang and this thing exploded in my sump of my saltwater tank!
Review: Solid heater with good, consistent performance - Solid heater with good, consistent performance. I replace these annually, 'need it or not,' so I have never had problems with a Cobalt. I figure critical equipment like a heater needs to be replaced at least annually to preclude any malfunction and minimize risk to fish.
