Aquael Ultra Day and Night Heater

Description

The Aquael Ultra Day & Night Heater is a next-generation electronic aquarium heater designed to do more than just heat water. Unlike standard heaters, it automatically recreates natural day and night temperature fluctuations, helping reduce fish stress and promote healthier behaviour.

Built with a shatterproof, fully waterproof plastic housing, this heater is ideal for aquariums with sensitive fish, large species, or turtles where glass heaters pose a risk. The ultra-precise electronic thermostat (±0.25°C) ensures stable temperature control without dangerous spikes.

How the Day & Night System Works

1. Day Mode:
   When ambient light is detected, the heater maintains the daytime set temperature.

2. Night Mode:
   When lights go off or the room darkens, the heater automatically lowers the temperature to the night setting.

3. Automatic Switching:
   No timers, no apps, no manual input — the light sensor handles everything.

This subtle temperature drop mirrors natural ecosystems and can noticeably reduce fish stress over time.

Installation & Usage

• Fully submerge the heater vertically or horizontally
• Secure using the included suction cups
• Set day temperature and night temperature using the control dial
• Place where water flow is consistent for best accuracy
• Allow 20–30 minutes before plugging in after placement
