Heating is a necessity for many species of aquarium fish, both in saltwater and freshwater tanks.

Unlike humans, fish cannot regulate their own body temperatures and so this is where the heater comes in.

They rely on the water that they’re living in to maintain their body temperature so it’s important that the water in your aquarium stays as stable as possible.

A large percentage of fish require warm water to survive, so unless you live in a year-long warm country, the likelihood is, you’ll need a heater to keep your tank at a consistent temperature.

In this guide, we’re going to take a look at why you need a heater, the different types of heaters available and then we’ll do a deep dive review into the seven of the best heaters to help you select the best aquarium heater for your needs.

It’s necessary to have a heater in most aquariums to replicate the natural environment and water conditions that specific species are used to living in.

A heater raises the water of the tank, usually to between 76 and 80°F, sometimes slightly cooler and sometimes slightly warmer; again this depends on the species you are keeping.

The heater also maintains a consistent temperature using a thermostat which is usually inbuilt. Changes in water conditions can lead to stress in fish which can be fatal if they are exposed to prolonged episodes of stress.

Keeping the water temperature consistent mimics their natural environment as large bodies of water (such as the sea) do not drastically and quickly change in temperature.

It’s also worth noting here that in some countries, fish keepers have the opposite problem of the weather being too hot and heating their tanks too much. In cases like this, you can use aquarium coolers instead of heaters.

FAQ

1. Where Should I Place My Heater?

Your heater should always be placed close to the filter inlet (or any other warm flow created by power heads etc.).

2. Do I Need Two Heaters?

If you live in a cold area, ideally, you’ll have two heaters to take the strain off one. Also if one fails, you can use a backup, like this example, which will keep the water at the same temperature.

3. Do I Need to Check My Heater?

One thing that we hear of all too often, are heaters overheating.

Along with your other daily checks which we’ve discussed here, you should check the temperature of your tank daily. Always include a separate thermometer (even if your heater comes with one) at the opposite end of the tank to ensure the water is heated properly.
