Aquarium Thermometer, Precise Control for Stable Temperature

The aquarium thermometer is a basic tool for monitoring temperature and avoiding fluctuations that stress fish and corals. In reef aquariums, the goal is often to maintain a stable range around 25–26 °C, with minimal daily variations.

Historically, the first common models were glass thermometers (formerly with mercury), which were gradually replaced by safer liquids like colored alcohol.

Today, digital probe thermometers are also available, valued for their quick reading and finer control when paired with a regulator. It's a good practice to check the reading consistency between two instruments, as accuracy can vary depending on the model.
