Many people believe that a nano tank is easier to care for and beginner-friendly. But do you know, the smaller a tank, the more temperamental it is? The water chemistry and temperature may frequently fluctuate within short spans, and the protein buildup happens sooner because of smaller water volume. 

Thus, they need frequent and dedicated maintenance, too—just like their bigger counterparts. 

That’s why, today, I have brought you a list of the five best nano skimmers to buy in 2022! 

The selection is made based on my personal experience with nano tanks and the day-long research I did on the internet, so you don’t have to.

Our Top Pick

The German-engineered Tunze USA 9004.000 Doc Skimmer is my top pick for the best nano skimmer in 2022. 

The surface skimmer will eliminate the oil and bacterial film floating in the water, while the bigger skimmer takes care of other impurities. Even more, this skimmer offers tight control over the microbubble size, which ensures consistent skim mate every time. 

Since it’s suitable for tanks up to 65 gallons, it will still work perfectly fine if I ever want to upgrade from my nano tank. In addition, with both internal and in-filter options for placement, this one leaves a minimal footprint. 

If you don’t want to take my word for it, check out the raving reviews on Amazon itself. Several people have vouched for it and mentioned how it effectively replaced and superlatively succeeded their old nano skimmers.

What Are The Advantages Of Using A Protein Skimmer?

A closed ecosystem of a nano tank is more prone to quick buildups of algae, food, plant waste, and fish waste, among others. That’s why a nano skimmer is crucial for a smaller tank under any circumstance. 

Here are a few advantages of using a nano skimmer:

Discourages Nitrate Growth 

Nano skimmers can maintain the tank’s nitrate level by retarding any nitrate buildup. They will remove the organic buildup before it breaks down and releases nitrogen compounds. 

Tackles Algae Bloom 

Algae is a constant source of misery for many of us, isn’t it? A nano skimmer reduces the level of phosphate, the algae food, in the tank, which will directly slump the algae bloom. 

Facilitates Light Penetration

Once all the gunk and oil floating around in the tank is removed, the light penetration will naturally increase. That’s even better if you have a coral tank, a planted one, or fish that love sunlight. 

Clearer Water Quality 

Since protein skimmers offer an almost endless supply of waste-binding services, it improves the water quality by leaps and bounds. The continuous production of waste-removing bubbles continues effective waste removal with little need for replacement media.

Clears Gunk Bypassed During Mechanical Filtration 

Mechanical filtration needs to be frequently cleaned or replaced. If you cannot do so, the trapped particles will either clog up the water flow or break down and bypass the filter. However, nano skimmers can efficiently remove the dissolved organics that bypassed the mechanical filtration. 

Increased Oxygen Level

Since protein skimmers facilitate proper gas exchange, the amount of dissolved oxygen in the tank increases, which, of course, is great for the tank’s inhabitants. And the subsequent reduction in CO2 levels helps to maintain a healthy pH level. 

How Does A Nano Skimmer Work?

So, you must be curious to know how nano skimmers that seem to offer so many benefits actually work? Nano skimmers are pretty impressive in terms of how they pack so many functionalities within such a small device. 

So, these skimmers work by injecting thousands of microbubbles into the water column, which binds to dissolved organics. And as the microbubbles rise to the top of the skimmer, the ‘dirty’ ones flow their way into the collection cup. 

This is similar to how waves keep the ocean clean. 

As a wave soars to the shore and stirs the water, it produces tens of thousands of microbubbles. And you may have noticed how the foamy broth on the top is often dirty, right?

Nature’s very own not-so-nano protein skimmer. 

How to Maintain A Nano Skimmer?

For all the things nano skimmers do for your nano tank, they’re surprisingly low-maintenance, if I dare say. However, it doesn’t mean you can take them for granted. Clean the collection cup every day, regularly check the intake pump, and conduct a thorough bi-monthly cleaning. 

Clean the Collection Cup Everyday

Since nano skimmers are equipped with smaller collection cups, they can fill up quickly. If you don’t empty them regularly, all the gunk and impurities will flow back into the tank. 

Regularly Check The Intake Pump

While you don’t have to clean the intake pump every day, you still need to regularly make sure that the pump/hose doesn’t contain debris and can suck in the water perfectly. 

Scrub the Collection Cup 

While emptying the collection cup, don’t forget to give it an occasional scrub that will eliminate all the coatings built on the cup’s inside.

A Thorough Bimonthly Cleaning 

Every two months, disassemble and clean the entire skimmer pump. Start with removing the pump base plate, pump cover, and impeller assembly with the help of a shaft and soak all the parts in equal parts water and vinegar. 

Also, clean the skimmer’s body using hot water, a damp rag, and liquid soap. And to clean the venturi, remove it and clean both sides with warm water and liquid soap once again. If any stubborn gunk is left, soak them in an equal mix of vinegar and water for about 24 hours and rinse. 

Lastly, don’t forget to clean the airline tube and wedge pipe and check all the electrical components. 

Conclusion: Best Nano Skimmers in 2022

So, that’s pretty much there’s to nano skimmers. 

To conclude, all the products mentioned in the 5 best nano skimmers list are exceptional in their own accord and deliver on the claims they make. But, remember, nano tanks require just as much care as their bigger counterparts—and sometimes, even more. So, get your beautiful nano tank a befitting nano skimmer today.
