Best Aquarium Heaters for Sale-Buying guide

Buying guide of aquarium heater

If you need more information to choose the best aquarium heater in the market, we invite you to continue reading this simple buying guide that will help you make your decision:

The first thing to consider is the size of the heater. This way, you will know if it will take up a small part of the aquarium, or if it will be too big for it.

The power at which the heater works is measured in W and the value depends on the aquarium. The larger it is (higher volume), the more power we will need to heat it. The most common is that they have a power between 40-150W more or less.

Temperature range
Some species of fish can only survive in very specific temperatures, so it is important that the heater can reach them. In this way, we will have to check the temperature range with which it allows us to work along your product sheet.

Fully submersible?
If it is totally submersible we will not have any problem if it falls into the aquarium… but if it is not, we will have to check the fastening system (for example, suction cups) and determine if it works well.
And then it will be easy for you to choose a good aquarium heater.
