Best Protein Skimmers For Nuvo Fusion 20 Aquarium

If you are looking to add a protein skimmer into your Nuvo Fusion 20, you will need to choose one that works great and will fit in the tank.

The Innovative Marine Nuvo Fusion 20 is a popular choice for a nano tank.

It is an all-in-one style tank that comes with a built-in filtration system.

There are a few pieces of equipment you may want to add to the tank like a heater and protein skimmer as these are not included with the kit.

Regardless of the tank size, you will need to choose the properly sized equipment that is suitable.

It can be challenging to find certain items for nano tanks as they are limited in available space. 

With the Fusion 20 aquarium, you will have a few options for mounting a protein skimmer. 

You can position it inside the rear filtration section, hang it on the back of the tank, or place it inside the tank. 

The following protein skimmers are all rated for at least 20 gallons and are perfectly suitable for the Nuvo Fusion 20 aquarium.   

Innovative Marine Nuvo Skim

The Innovative Marine Nuvo Skim skimmer is the top choice for the Nuvo Fusion 20. It is rated for up to 25-gallon tanks and is specifically designed to fit various Innovative Marine aquariums.

It’s not very often that you find a DC-powered nano skimmer but the IM Ghost protein skimmer is one of them. It was the industry’s first-ever direct current nano skimmer.

It’s the perfect match for the Nuvo Fusion 20 and will fit easily into the second chamber of the filtration section. 

Features and specs:

  • Improved model
  • DC powered needle wheel
  • Large air intake
  • Dual silencers
  • Rubber feet to reduce noise
  • Bubble plate diffuser
  • Low profile design
  • Dimensions: 3.58” L x 2.28” W x 9.84” H
  • Designed to suit the IM Nuvo Fusion 20
  • Energy-efficient DC motor
  • Quiet 
  • Easy to maintain
  • Costs more than other nano skimmers
  • It takes some time to get fine-tuned.

Tunze 9001

Another great protein skimmer choice is the Tunze 9001. This skimmer is very reliable and works well.

The Tunze 9001 will fit into the center rear filter chamber, but you will need to perform some modifications.

The Nuvo Fusion 20 is designed with dual outputs that form a Y-shaped tubing which is attached to the return pump.

The best way to install the Tunze 9001 is to remove the Y-shaped tubing and use 2 separate return pumps instead of 1.

This will open up space in the center chamber for the skimmer to fit.

The other modification to perform is to remove the magnet that holds the skimmer onto the glass from the skimmer. You will have 2 magnet pieces.

Then attach the thinner magnet onto the side of the skimmer body using a reef-safe glue.

This will allow you to insert the skimmer into the chamber and hold it in place by the magnet attached to the outside of the glass.

Here is a video showing the modifications. 

Features and specs:

  • Rated for up to 37-gallon tanks
  • Anti-overflowing system
  • Airflow regulation and silencer
