What temperature should you set?
Most tropical fish, bettas included, thrive at a steady 24-28°C. In India it's the night-time and winter swings, not daytime heat, that stress fish - a thermostatic heater like the HG045 holds a steady temperature through them. See our aquarium temperature guide for the ideal setting for your species.
How to set up and use it
Submerge the heater near your filter flow for even heat and set your target temperature. Keep a separate thermometer as a cross-check, position it well (see our placement guide), and follow our heater safety guide.
