Frequently Asked Questions

Which aquarium heater is best?

It completely depends on the type of aquarium, your local climate, the type of fish, and the size of the aquarium. Some types of fish are more sensitive to temperature than others, and those need more precise heaters. That’s why we compared the advantages of our heaters above so you can get a better idea on which one is more suitable for you.

How many watts should my aquarium heater be?

Again, this also depends on the size of the aquarium and the type of heater you’ll install. Obviously, a smaller aquarium would need less energy to heat, and the larger aquariums require more energy. Typically, in an aquarium between 40 to 80 cm in length, a heater will consume anywhere from 25 to 100 watts.

How do I know if my aquarium heater is working?

Each heater gives you special indicators letting you know it is doing its job. Some will have an electronic display, others a light. If you’re afraid your heater isn’t doing its job properly, it pays to have another thermometer to keep track of the temperature inside the fish tank. That way, you’ll always be sure it is the right temperature.

What heater size do I need for my fish tank?

Heater sizes vary to accommodate fish tank sizes. If your tank’s capacity is anywhere from 10 litres to 25 litres (2-5 gallons), then you’ll probably survive with a small heater. If, on the other hand, you have a large aquarium with a water capacity of 100 litres (25 gallons), you definitely need a larger heater.

Is it necessary to have a heater in a fish tank?

There are a lot of variables that determine whether you need a heater or not, but the answer, most often, is yes. You have to take into account your local climate and your room temperature: does it fluctuate a lot? If yes, you definitely need a heater. Fish are extremely vulnerable to large fluctuations of temperature. The type of fish you want to have in your tank also matters – some fish are hardier than others and can survive in most temperatures above zero, some require a certain temperature.
