What is the Best Nano Skimmer?

The best nano skimmer is the one that fits your aquarium and doesn’t break the bank. There are a variety of styles and brands of protein skimmers available at different price points (see our list below) but our absolute favorite is the Comline DOC Protein Skimmer 9001.

The Comline DOC Protein Skimmer 9001 from Tunze is a favorite among nano reef tank owners. It is manufactured by a highly reputable brand, one of the smallest options on the list, and does an excellent job at skimming your water due to its updated technology. It is rated for aquariums up to 37 gallons.

What is a Nano Skimmer?

A protein skimmer is a device used to remove dissolved organic waste pollutants from your aquarium. Whether you have a tropical fish tank or a saltwater reef, all fish and invertebrate foods add organic substances to the water as they break down. If these organics remain in your tank, they will eventually decompose and be recycled into nitrate, ammonia, and other harmful substances.

Skimmers remove organic substances before they have a chance to decompose, helping your water parameters stay a lot more stable.

Nano skimmers are for nano tanks, one of the hottest trends in aquariums right now. Nano tanks are typically under 10 gallons, though definitions vary and range up to 40 gallons. Nano tanks are popular because they take up minimal space, make keeping a tank significantly cheaper and more manageable, and add beauty to your home’s decor.

Because they’re designed for nano tanks, nano skimmers are often smaller, quieter, and almost unnoticeable.

What Does a Protein Skimmer Do?

Nano protein skimmers remove organic waste by releasing microbubbles into your tank, which the organic waste will stick to. The bubbles then float to the surface, carrying the waste, and the skimmer removes the top layer of scum from the collection area.

Each nano skimmer varies slightly in how it functions, but this is the basic idea. Understanding this is important for picking the best nano protein skimmers and deciding which is the perfect fit for your tank.

Are Nano Protein Skimmers Worth it?

In the world of aquariums, bigger is usually easier. This can be counterintuitive to new aquarists as a bigger tank seems like a more significant investment in time and resources. However, it is also inherently more stable, as there is more water to essentially dilute the concentration of any harmful water parameters such as ammonia or nitrates.

With this logic behind us, the most difficult aquarium to maintain is, without a doubt, the nano reef aquarium. These aquariums are typically less than 30 gallons (sometimes as small as 5-10 gallons), have all the complexities of a larger reef aquarium, and are subject to water quality that can rapidly change and reach critical conditions. Because of these challenges, a nano protein skimmer is a useful tool in maintaining consistency in your tank. Through the process of foam fractionation, they remove contaminants and organic compounds that will break down and release ammonia.

We consider protein skimmers as essential to saltwater tanks as things like RO DI systems, the right coral food, biopellet reactors, wave makers, and the right reef salt.

What Happens if I Skip the Skimmer?

If you forgo purchasing a protein skimmer, you will need to make changes to your aquarium maintenance. First, plan on doing water changes weekly. In a nano reef aquarium without a skimmer, change 10-20 percent of the water weekly.

Additionally, if you’re operating without a protein skimmer, your margin for error will be pretty small. You’re going to need to check water parameters more frequently. For example, if you’ve overfed your tank, water chemistry can change a lot faster so pay close attention to any changes that you see. We’d also recommend thinking about additional options for your tank like filter floss.

How To Maintain A Nano Skimmer

Protein skimmers get pretty dirty. They’re incredibly important to the overall functioning of your tank so make sure to give it the proper attention to keep it operating well.

Depending on the size of your tank and the bioload of your aquatic critters, we recommend cleaning the collection cup three times a week. If your water is extremely clean, you might be able to get away with it once or twice a week. If your tank is super stocked, daily cleaning might be needed.

Skimmate, the term for the dissolved organics that accumulate in the collection cup, also known as the nasty stuff, is typically easy to clean and can be removed with a simple rinse and wipe down with a clean pad.

The body of the skimmer can grow coralline algae over time. This is definitely more difficult to clean. We recommend cleaning the body of the skimmer about twice a year.

To clean the body of the skimmer, drain all of the water, remove it from the sump or tank, and let it soak in a bucket with a vinegar solution. We recommend one part white vinegar to 10-20 parts of water. After letting it soak, the algae should be much easier to wipe away.

Why are Protein Skimmers so Expensive?

Protein skimmers are expensive because they’re in high demand by aquarists and are a piece of equipment that runs 24/7 in your tank so the construction, design, and materials have to be reliable. The pump is typically the most expensive component. Pumps are expensive and often have to be modified to work for aquarium skimmers. If you’re handy, you can likely craft a homemade protein skimmer on your own but if you don’t know what you’re doing, we recommend purchasing a protein skimmer designed by professionals.

Conclusion

The best nano protein skimmers are designed to be small and powerful. They can help you maintain your tank’s ecosystem by removing pesky organic compounds and waste that would otherwise decompose into harmful compounds in your water. If you’re looking for a protein, we recommend choosing one that is researched in this guide.
