What temperature should you set?
Most tropical fish thrive at a steady 24-28°C; marine tanks around 24-26°C. A large body of water changes slowly, so a correctly sized heater is essential. See our aquarium temperature guide.
How to set up and use it
Submerge the heater near strong flow for even heat across a large volume, mount the external controller outside, and set your target. Keep a separate thermometer as a cross-check and follow our heater safety guide; two heaters at opposite ends heat the biggest tanks most evenly.
