Ultra Heater D&N 100W – aquarium heater

The Ultra Heater D&N 100W suits aquarists who keep fish or aquatic plants in 60–100 l tanks and want a heater that holds a set temperature while also reproducing a daily temperature cycle. Its very slim profile fits into the tank without drawing attention away from the aquascape.

Why it matters

• Day & Night function: the heater changes water temperature automatically, making it cooler at night and warmer during the day.
• Electronic thermostat: the manufacturer specifies a control precision of ±0.25 °C across a 20–33 °C setting range, which can be used to raise temperature during treatment of diseases such as ich.
• Shatter-resistant housing and overheating protection: the body is non-breakable and a built-in thermal cut-out guards against overheating; the manufacturer states it is safe for fish such as catfish and stingrays.
• One-touch control: a single button and an LED ring show both the current and the programmed temperature, and a two-sided hanger allows installation in the tank.
