Therm 300W

The Newa Therm 300W automatic heater is the flagship model in the Therm series, built to stably heat large freshwater or reef aquariums up to 300 liters. The reinforced quartz glass tube protects the heating elements from knocks with heavy rock layouts. Equipped with a high-precision thermostat, it prevents temperature drops.

As the most powerful model, it is ideal for large community tanks or aquariums with high-flow filtration systems (sumps) that dissipate heat rapidly.
