What is a Protein Skimmer?
A protein skimmer is a device that purifies aquarium water by removing organic materials such as toxins, uneaten foods, excess bacteria, waste from the animals, etc. Basically, protein skimmer works by a system called fractionation. It creates bubbles and takes all the compound with it.
Moreover, with a protein skimmer, you can remove compounds from your tank before they can break up and make you tank water nasty. This device lowers the amount of nitrate buildup and stops algae from spreading all over the tank.
Why it is called Protein Skimmer? It’s because they use the polarity of the proteins in order to remove different organic compounds from the water. Protein skimmers have a chamber called reaction chamber which creates tiny bubbles and cleans the water.
How Does a Protein Skimmer Work?
As we said earlier, all protein skimmer uses a system called foam fractionation. To put it straight, foam fractionation is a simple process of taking waste particles out of the tank water through foam or air bubbles.
Every skimmer comes with a water pump, that’s pretty obvious. So the water pump pumps water from the tank and air from the air intake into the main body of the skimmer.
The pump has a motor-impeller which creates tiny bubbles by mixing water and air together. As the bubbles are loaded with air they float to the top. And the waste particles stick themselves to the bubbles and along with the bubbles they ride to the top and overflow into the collection cup.
Protein skimmers don’t work well on freshwater. They’re mainly used on saltwater due to the attraction of waste molecules to the surface of air bubbles. In fresh water, there’s just not that much molecular attraction to allow a protein skimmer to work.
Most of the protein skimmers come with the flow controller. It actually works by narrowing or expanding the water outlet, depending on how much water you want to skim.
Here is a great video to know more about how protein skimmers work and if you really need a protein skimmer in your tank –
Types of Protein Skimmers
There are different types of protein skimmers available suited to different water tanks. Choose any one that suits your tank best. Here are the 4 types of protein skimmer that are most popular:
1. HOB Protein Skimmer
It is actually the short form of ‘Hang on Back’. As the name suggests, this type of protein skimmer hangs on the back of the water tank. HOB skimmers are best for small or nano reef aquariums which don’t have a sump. It simply hangs on the rim of the aquarium and works nicely from there.
2. Inside the Tank
These are the mini version of the protein skimmer and designed for small aquariums. Plus, these skimmers are small, so they don’t take a lot of space inside the tank. They work very effectively in removing organic compounds.
3. In Sump
You might have already guessed, these protein skimmers are designed for water tanks that run sump. In sump protein skimmers come with lots of options in terms of functionality and size. They are known as one of the best tank water cleaning machines and they are expensive too. The price depends on the features and size.
These type of protein skimmers run externally from the tank or sump. The sump sends water to the skimmer and the skimmer purifies the water and returns it back to the tank. These skimmers are not so popular.
These are only the basic types of protein skimmer. They are available in different types of designs too, which we will discuss in the buying guide section.

How to Buy the Best Saltwater Protein Skimmer?
As the market is flooded with different protein skimmers, choosing the right one can be really tough. In order to get your hands on the right one, you have to check a few factors that we are going to discuss below:
1. Size Rating
The size is of the protein skimmer is the first and the most important factor to be considered. Different sizes of skimmer are suitable for different sized aquariums. Plus, differently sized protein skimmer has different skimming capabilities.
You have to choose a skimmer that suits nicely with your water tank. For example, if you choose an undersized skimmer for your tank, it might not be able to clean your tank water properly. It would be wise if you choose a skimmer which has higher size rating than your aquarium size.
Another vital part of a protein skimmer is the pump. A pump is what produces the bubbles and bubbles are what cleans the waste particles. In order to get an effective cleaning, you have to choose a pump with needle wheel impeller. Because the impeller wheel creates a large number of small bubbles which cleans the water effectively.
Mainly protein skimmers come in three different designs: Air driven, venture-driven and impeller skimmer.
These skimmers are also known as air stone skimmers. They come at a cheaper price but not really that much effective. Air driven skimmers use old irritating loud air pumps and make large bubbles whereas small bubbles clean more organic compounds.
The bubbles of these skimmers float up and pump the water down against the bubble flow. This is how air-driven protein skimmer mainly works.
Additional Read: Best Aquarium Air Stones
These type of skimmers have a valve called Venturi which is meant to suck up the air. These skimmers mostly pair up with powerful motor pumps in order to create a large number of air bubbles. They are better in performance than the air-driven skimmers.
Impeller skimmers pump up bubbles through a needle wheel in order to slice the bubbles into smaller pieces. This is a great feature because a large amount of smaller bubbles can clean the water more effectively.
4. Build Quality
For a moment let’s put the performance aside and think about the build quality. Performance and build quality are equally important. There is no point of having a high-performance if the machine’s material breaks down within no time. So be wise and choose one that is made of high-quality materials.
5. Collection Cup
The collection cup is the place where all the waste particles get stored and from where you pick all those waste. It is also an important factor to choose a large and simple collection cup that is easy to clean.
If you choose a small collection cup, you’ll have to clean up the cup multiple times, whereas a large cup will require cleaning once in a week. Plus, complicated collection cups will make it really hard for you to clean them. So don’t forget to choose a collection cup that is large and also simply designed.
6. The Shape of the Skimmer Body
Only a smooth path from the body to the collection cup will help the bubbles to float at the top and fall into the cup so that you can easily remove them. So the body shape is important. Cone, wineglass, and hybrid these are the effective body shapes which give the bubbles a smooth way.
7. Reaction Chamber
Try to pick a skimmer with a large reaction-chamber because the main action happens there. The bigger the chamber, the larger number of bubbles it will produce.
8. The Brand
You should go after well-known reliable brands. A good brand will have dependable products, will provide premium customer service if you face any trouble during the setup.
Here are some reliable brands: Reef Octopus, Tunze, vertex, and AquaMaxx.
You’ll find a lot of protein skimmer which comes with a motor that makes irritating noise during the operation. Make sure you avoid those types of skimmer because you won’t be able to sleep or read peacefully.
Fish tanks are mostly placed on the drawing rooms where all the guests sit and make conversation. So try to pick a protein skimmer that comes with a classy design. But don’t go mad after the look or don’t choose the look over quality.
Budget is always an issue for some people and that’s pretty normal. But most people go after cheap products just because they are cheap. They don’t even think about the quality and ends up spending more bucks in the long run.
If you are in a tight budget, we urge you to take some more time and gather some extra money and purchase the one that has higher quality. Trust me, you will thank us later.
Benefits of Owning a Protein Skimmer
- The aquarium water will get dirty after a certain period of time and that’s pretty natural. Marine inhabitants cannot survive in the nasty water and that’s where a protein skimmer strikes. The protein skimmer will wash off the dissolved organic compounds from the water which will increase the oxygen level in the water and the fishes will be healthy.
- In dirty water full of nitrates, algae spread all over the tank pretty fast and a skimmer can prevent that nicely.
- In cloudy water, the light can’t penetrate well which makes the fish tank look darker. As protein skimmer cleans the water perfectly, the light will shine amazingly inside the fish tank.
- If you use protein skimmer regularly, the overall health of the marine animals (including corals) will improve too. Fishes will be more playful and at the end, that’s going to please you.
Frequently Asked Questions
Do I need a protein skimmer for the freshwater tank?
Using a protein skimmer in freshwater is not suitable because there is a substantial difference in the surface tension of the two types of liquids.
In salt water there is not much difficulty in producing micro bubbles needed for foam fractionation to be effective and quite efficient.
This does not happen in fresh water, or only happens when extremely high dissolved organics are present in the water. Some heavily stocked Koi or goldfish ponds do use foam fractionation or forced air drip towers to skim off the proteins.
Also, generally in freshwater it is cheaper and easier to do partial water changes frequently and at high percentages of tank volumes rather than to use higher technology filtration techniques, which is the opposite of the situation in salt water.
What is the best HOB (Hang On Back) protein skimmer?
There is no definite answer to this. The skimmer that worked great with me, might not do the same with you. You have to choose a skimmer according to your tank size and water. Though, we think the reef octopus classic 100 hob protein skimmer is overall a nice one.
Is the protein skimmer a filter?
Yes! A protein skimmer works like a filter which cleans the nasty aquarium water in order to keep the marine inhabitants healthy. There is an added advantage with a protein skimmer. It removes waste before it breaks down into harmful toxins.
It’s Time to wrap up the article. We have tried to give you a basic idea on protein skimmers so that you can easily buy the best available protein skimmer within your budget.
