Ultra Heater D&N 150W – aquarium heater

This 150 W heater is intended for keepers of freshwater and marine tanks of 90–150 l who want a heater that holds a set temperature and can follow a daily temperature cycle. Its 20.8 cm length and slim profile let it sit low in the tank with less visual impact on the layout.

Why it matters

• Day-and-night function: the heater lowers the water temperature at night and raises it during the day, which the supplier describes as imitating a natural daily cycle.
• Stated thermostat precision: the electronic thermostat is specified at ±0.25 °C, which keeps the temperature steady for sensitive species.
• Single-button control: the ONE-TOUCH system uses one button and an LED ring that shows the current and the programmed temperature.
• Built-in protection: a thermal cut-out guards against overheating, and the heater has a double-sided hanger for mounting.

What it works with

The supplier lists use in freshwater aquariums, marine aquariums, paludariums, aquaterrariums and terrarium pools. Its 90–150 l tank range and 150 W output define the size of the setup it suits, and the supplier also notes it is suitable for larger, strong fish and aquatic turtles.
