Finding the best aquarium heater to suit your needs can be a daunting task with so many products on the market to choose from. We take a look at the top 3 aquarium heaters designed specifically for nano aquariums.
For most “normal” room temperatures, you can figure on 100 watts for a 20-gallon to achieve proper heating.
Why You Need An Aquarium Heater
If you plan on keeping tropical fish, then it’s a no brainer that a heater is required. Tropical fish thrive in temperatures 76° to 80°F (25° to 27°C). Fish are cold blooded animals and cannot regulate their body temperatures. As such, having a constant and appropriate tank temperature helps your fish thrive.
If you live in an area that has cold weather, then the lack of a heater can be detrimental or fatal to your fish.
In conjunction with your heater, its good practice to have a thermometer visible for you to check the water temperature with a quick glance.

Uncommon, substrate heaters are placed underneath the substrate and helps to promote plant growth. Consisting of wires as the heating element, the heat travels through the substrate and into the water.
