TECHNICAL SPECIFICATIONS

M HEATERS

Why is my M Series heater not reaching the desired temperature?

If the difference between the ambient room temperature and the heater’s set temperature is more than 3 °C (8 °F), additional heating capacity is likely necessary. You can either add another heater or upgrade to a more powerful unit.

Are M series heaters fully submersible?

Yes, M Series heaters are fully submersible. The instructional manual specifies a minimum water level.

My heater won’t hold a temperature of 80°F (26.7°C) in my aquarium. Do I need to add more heating power?

Most likely the answer is yes. If you wish to maintain 80°F in your aquarium, you will likely need more power or begin by warming up the room itself as ambient temperature is very important. The cooler the room is, the greater the energy requirement to increase the aquarium temperature.

Are M series heaters fully submersible?

Yes, M series heaters are fully submersible.
