200 W submersible heater with digital temperature display, dual sensors, and fish guard.
Consider: The 14-inch body can exclude shallow tanks. Compare that height with the mounting position and water depth in the instructions before ordering.
Heaters · electronic-adjustable
50 W fully submersible adjustable heater in a thermal-plastic housing.
Consider: A cold room can demand more heat than the gallon rating suggests. Compare your coolest room temperature and target water temperature with the manufacturer’s sizing chart.
Heaters · electronic-adjustable
100 W fully submersible adjustable heater with an electronic thermostat.
Consider: The catalog and manual disagree above 30 gallons. Do not choose one solely from a 40-gallon claim; use the current exact-model sizing chart with your room-to-water temperature rise.
Heaters · preset
50 W preset submersible heater with heating and standby indicator lights.
Consider: Preset to 78°F with no user adjustment. Choose an adjustable heater if your established care plan needs a different target.

Heaters · electronic-adjustable
Flat 100 W fully submersible electronic heater with push-button temperature setting.

Heaters · adjustable-submersible
Slim 50 W adjustable submersible heater with a 66–86°F maker-published control range.
Consider: A cold room or open tank changes the heating load. Use the exact-model sizing chart with your coolest room temperature before choosing from the gallon rating alone.
