If you recently purchased the Nuvo Fusion 20 all in one aquarium, you might be looking to add a new heater that will work well and fit in the tank.

The Innovative Marine Nuvo 20 is a great nano tank and is one of the more popular choices. Although this tank comes with a built-in filtration section and return pump, it does not include a heater with the kit. 

With all aquariums, it is important to choose the right sized heater that is not only powerful enough but fits properly in the tank. This is even more important when dealing with nano tanks. 

Smaller tanks will mean smaller sized equipment. The Nuvo Fusion 20 has a chamber in the rear filter section that will fit a heater. You have the option of mounting a heater inside the display area, but most people will fit it in the back where it is hidden away from view and you won’t have to worry about livestock being around it. 

The rear section of this tank has a baffle height of 7.9”-9.8” so you don’t really want a heater that is taller than that. I find that an 8” heater will work perfectly in the Nuvo Fusion 20. 

A good guide to follow is to choose a heater that is a minimum of 3.5-5 watts per gallon. So a 75 watt to 100-watt heater is sufficient for a 20-gallon tank.

The following heaters are all rated for 20 gallons or more and will fit properly in the rear chamber of the Nuvo 20.

Another great heater choice is the Eheim Jager 75 watt. These heaters have been around a while and are proven to work. They are trusted by many and are my personal favorite heater for all tank sizes.

Do you need a heater for the Nuvo Fusion 20?

Yes, all saltwater fish require a certain temperature to stay healthy. Many fish are sensitive to temperature changes and you should maintain a constant temperature at all times. Although there may be a range of temperatures that are safe for specific fish, it’s more important to keep the temperature constant than fluctuating within that range. A good quality heater will keep the water temperature in your tank at the desired level usually within +/- 0.5 degrees. 

 

Can a fish get burned by a heater?

Yes, it is possible for a fish to be burned from a heater. Usually, this happens when they get trapped in between the heater and the glass. With the Nuvo Fusion 20 aquarium, you have the advantage of putting the heater in the rear filtration section and avoiding your fish interacting with a heater in the tank. 

 

Do you need a heater controller?

I always recommend that you add a heater controller to your must-have list. The Inkbird temperature controller is one of the best purchases you can make in the aquarium hobby. It will control your temperature and shut the heater off in the event of a heater malfunction causing it to stick in the on position. The Inkbird is not expensive and worth their weight in gold. I won’t have a tank without one. They are available on Amazon here. 

 

Summary

Choosing a heater that is properly matched for your tank is very important. Although the heaters mentioned here will fit in the rear filter chamber, you also have the option of using a larger heater inside the tank. A small heater of this size is affordable and easy to buy so if you need to replace them it won’t break the bank.
