What It Is

The TMC Therm is a submersible aquarium heater with an adjustable thermostat and an easy-to-read temperature scale. Available in several wattages, it provides straightforward heating for marine and freshwater aquariums.

Why We Like It

ItÕs a simple option when you want to set the temperature directly on the heater. The operating light shows when itÕs heating, and the range of sizes makes it easy to match the wattage to your setup.

Choose around both water volume and room temperature. A tank in a cold room needs more heating capacity than the same aquarium in a warm living room.

Choosing Your Heater

Model Suggested Aquarium Volume Typical Use
25W Up to approximately 25 litres Small nano aquariums
50W Up to approximately 50 litres Nano reefs and small tropical tanks
100W Up to approximately 100 litres Small to medium aquariums
200W Up to approximately 200 litres Medium aquarium systems
300W Up to approximately 300 litres Larger aquariums or part of a multiple-heater setup

Volumes are a starting guide. Room temperature, target water temperature, lids and heat loss affect the wattage required. Larger systems may benefit from multiple heaters.
