What temperature should you set?
Most tropical fish thrive at a steady 24-28°C; marine tanks are usually kept around 24-26°C. A thermostatic heater like the HG102 holds a stable temperature through India's night and winter swings. See our aquarium temperature guide for the ideal setting.
How to set up and use it
