Best Nano Protein Skimmers: Reviews

Mame Skimmer III

Right off the bat, we have here is a super high-quality protein skimmer. No, this unit is not cheap, not in the least.

This unit comes in at 3.94 x 3.94 x 11.42 inches, thus making it ideal for vertical placement, something that makes it ideal for aquariums that are not very wide or long, but are fairly deep.

What you might like here is that the color of this protein skimmer is called glass, or in other words, this unit is completely transparent, or at least for the most part, which means that it won’t affect the aesthetic appeal of the aquarium.

We do want to say that in terms of durability and build quality, this has to be one of the best ones out there. On a side note, it’s also pretty convenient because it should be compatible with most all-in-one fish tanks.

This particular protein skimmer features a so-called air driven design, which means that it doesn’t use all that much energy, and it also doesn’t produce any heat in the tank. This is ideal because it won’t raise the tank temperature, thus allowing for healthier fish and easier tank maintenance.

Of course, the main purpose of this protein skimmer is to remove a variety of dissolved organic waste from the water and something that it does extremely well. The air to water interface created by this unit is very efficient, thus allowing for great efficiency and functionality.

Remember that this protein skimmer does not use any filtration media. It is also worth noting that this protein skimmer is extremely easy to maintain.

Eshopps Nano Skimmer

Here we have another high-end, high-quality, and long-lasting nano protein skimmer. Remember, this nano protein skimmer is made in the USA, and it’s made with the best possible materials. It might be a fairly expensive protein skimmer, but we think that it is definitely worth the investment.

Unlike the above protein skimmer we looked at, which was almost a foot tall, this one is much smaller and therefore even better suited for very small tanks such as nano fish tanks. This unit comes in at 5 x 2 x 4 inches, thus making it ideal for even the smallest of tanks.

Of course, what this high-end protein skimmer does very well is the removal of a variety of dissolved organic waste from the water. It uses a very special type of filter media that is extremely efficient at this purpose.

What you get here are so-called Bio Filter Balls that engage in biological water filtration. This skimmer also performs regular protein skimming functions by injecting bubbles and creating a functional water/air interface.

The filter media does not need to be replaced all that often. Although for the best results you will want to replace it on a regular basis.

You may also like how this particular unit is designed to be extremely quiet and energy-efficient. So it won’t annoy you as it runs all day long and it won’t kill your bank account either.

Tunze 9004 Nano Protien Skimmer

What we have here is so far the most expensive protein skimmer on the list. With that being said, we are big fans of the old saying you get what you pay for. Yes, you’ve already heard it once today and now you heard it again, because simply put, it’s true.

This might be a very expensive and high-end protein skimmer, but that means that it’s also quite durable. We have come to the conclusion that this is by far one of the most durable, long-lasting, and efficient protein skimmers that your money can buy.

This protein skimmer uses what is called flash skimming. It’s a very efficient method of foam production that mixes with the surface water to remove a variety of pollutants from the water.

This skimmer also features a system to help prevent it from over foaming and spilling over into your tank.

What you might also like here is that this unit features a high-efficiency synchronous motor combined with a self-cleaning impeller. It is also worth noting that this protein skimmer is very energy efficient, not to mention fairly quiet too.

This is actually a fairly large protein skimmer, about the same size as the first one we looked at, as it comes in at 4.3 x 3.5 x 12 inches.

So, while it’s not exactly a massive protein skimmer, we definitely think that you’re going to have to have one of the larger nano tanks out there for it to fit. It’s going to need at least a foot of water depth to function. It’s definitely on the larger end of the nano spectrum.

Marine Bioskim DC A10 Nano Protien Skimmer

What you need to know here is that this particular protein skimmer is designed specifically for marine and saltwater use only. Under absolutely no circumstances should you use this product for a freshwater fish tank.

In terms of the size, this protein skimmer comes in at 4″ x 2.3″ x 11.2″. So it’s not overly large, but you do need the fish tank to be fairly deep in order to use it. Something that is important to note is that this protein skimmer is rated for aquariums after 34 gallons in size, but no larger.

Remember, this is an internal protein skimmer, so it will take up space within your fish tank. What’s nice is that this unit features an adjustable height hanger. So you can hang it on the side of your tank, something that can help control how much space you end up needing for it.

We do also like how this unit is transparent for the most part because it helps to keep the aesthetic appeal of your aquarium intact.

When it comes to the creation of bubbles for the removal of proteins and other organic dissolved ways from the water, this is one of the best options that you have at your disposal.

Once all the proteins are removed from the water, they go into a collection cup that you can simply remove, empty, and clean.

What you may also like is that this unit comes with an external air silencer to help control how much noise it makes. Let’s face it, nobody wants a noisy protein skimmer, thus making this a rather perfect option to consider.

Aquatic Life 115 Mini Internal Nano Skimmer

If you’re looking for a small, simple, and affordable protein skimmer, then this is a great option to consider. It is by far the most affordable option on the list today. It’s ideal for those working on a tight budget.

In terms of small and compact protein skinners, this one comes in at 3 1/2 x 3-1/4 x 10-5/8 inches. Therefore, making it one of the most compact units on the list today.

Yes, this is an internal protein skimmer, so it does take up a bit of space inside of the tank. However, it does come with simple mounting clips and suction cups that you can adjust for height and position. You can place this skimmer more or less anywhere in your fish tank.

Keep in mind that this unit is designed for saltwater aquariums up to 30 gallons in size, but no larger. This unit comes complete with a proven middle wheel impeller that increases air to water contact for fast, efficient, and maximum protein removal.

We do want to say that this is not the most durable or long-lasting protein skimmer. But if you maintain it regularly, it should last for a couple of years.

Buyers Guide – Best Nano Protein Skimmers

Before you go out and buy any protein skimmer, there are a few important things that you need to know.


The first thing that you need to consider is that there are four main types of protein skimmers available. What we can tell you is that the four main types include hang-on-back skimmers, in-tank skimmers, external protein skimmers, and in-sump protein skimmers.

When it comes to nano fish tanks, what you need to keep in mind is of course that you have a limited amount of space.

So, while many protein skimmers are in-tank or internal, realistically you are better off with one that goes into a sump or hangs on the outside of the tank. Nano fish tanks are already tight for space, so you don’t want a huge internal unit.


You do also want to consider how much space you have to spare in your fish tank. Particularly when compared to the size of the protein skimmer in question.

We are aware that the vast majority of the skimmers that we looked at today are internal models, so we have done our best to choose some of the smaller ones.

It’s probably a good idea for you to bust out that measuring tape before you make a purchase.

Longer Media Life

The vast majority of protein skimmers function by injecting air bubbles into the water, to which proteins then adhere to.

Most protein skimmers do not use filtration media. Although there are a select few that may come with additional mechanical or biological filtration. However, this is not a defining feature of protein skimmers.


What is a nano protein skimmer?

A protein skimmer is a tool used to removed dissolved and solid organic materials from the water. A nano protein skimmer is simply a miniature version.

Why are protein skimmers important for nano tanks?

Metal tanks are of course very small and contain a very limited amount of water. The less water tank contains the more efficient the filtration and cleaning of it needs to be.

It is important that fish waste, uneaten foods, and other organic compounds be removed from the aquarium water. This ensures that they do not breakdown and create ammonia, which is extremely poisonous to fish.

When do you need to use a protein skimmer?

You need a protein skimmer. If you have a large bioload compared to the amount of water in the tank. If you have a lot of fish, creating a lot of waste, but fairly inefficient filtration, then a protein skimmer is called for.

Conclusion – Which is the Best Nano Protein Skimmers?

Based on its size, efficiency, and ease of use, we think that the best nano protein skimmer is the Eshopps Protein Nano 10-35G Skimmer. It even comes with added biological filtration media.
