Things to Consider Before Buying a Protein Skimmer

You have to consider some things before shopping for a nano skimmer. If you don't want to waste your valuable time and money in a flimsy and unwarranted skimmer, then you should pay attention to these following details:

Aquarium Type

When choosing for a nano skimmer, make sure that you know the kind of aquarium you have. Of course, you cannot expect that one nano skimmer could work on freshwater and saltwater aquariums. It is not a one-size-fits-all device.

Therefore, you should check the capacity of the nano skimmer first before you buy it. In this way, you will know if your prospect is compatible with your setup or not.

Moreover, we have to emphasize that size matters as well. Because we are talking about nano aquariums, you should choose a model that would fit on them as well.

On the flip side, standard-sized protein skimmers will work best on regular or large fish tanks.


A nano skimmer is a complex device. It is not something that you can label as a rocket science. Therefore, you need to assess the quality and functionality of the brands that you want to buy.

Moreover, you have to look for the unit's manual or instruction so that you will know how to operate the skimmer properly. Otherwise, you will have a bad time at your home.


The ozonizer is the most important component of a skimmer because it is responsible for creating the bubbles that cleanse the water. Ideally, you want the skimmer to generate fine bubbles.

In this way, it can be able to expel those harmful microorganisms efficiently. Furthermore, it can stabilize the pH level of the water as well.

The best nano skimmer is the one that allows you to control the amount of its bubble production. Sometimes, too many bubbles could disrupt the ecosystem of your aquarium.

These are the basics of a nano skimmer. Now is the proper time to introduce the best brands of nano skimmers on the market today. Read on!

Final Verdict

Regardless of your choice, you have to remember that your aquarium needs a cleaning mechanism. If you want to take care of your hobby (and your marine friends as well), then you have to invest in a nano skimmer and other related devices. In this way, you will not worry anymore about the cleanliness and safety of your marine environment.

Among the products we featured, we deem that the Bubble Magus QQ1 is the best nano skimmer. It is easy to install and operates on low energy. Furthermore, all of its parts have premium and intuitive design.

Therefore, you can guarantee that it can expel those unwanted microorganisms and other mess out from your water.
