Best Protein Skimmers Reviews for a Healthy Aquarium

This article, we will be talking about some of the equipment or different pieces of equipment that some of the beginner hobbyists or even aquarium keepers who are a few years old into their tank keeping journey, may find a bit confusing or alien.

Overall, this is the what, why, and which on the subject.

Let’s talk a bit about Protein Skimmers. Protein skimmers, according to us, are one of the best additional equipment you can have in your tank, especially important if you have a reef tank.

Like with everything else in the modern-day, there are loads of new technological changes being achieved in the aquarium keeping world. Protein skimmers are one such gift of technology that make this hobby easier and overall contribution to the all-round well being of the fish in the tank.

Here we will discuss what exactly are Protein skimmers, what do they do, are they worthy investments, and which Protein skimmer exactly meets your demands. So let’s begin.

What are Protein Skimmers

Protein skimmer is basically a mechanical filter which works in removing organic materials from the water in your aquarium. They also work in removing excess bacteria and toxin released by the corals, waste products from the animals, uneaten food and also clear the unnecessary colour from your water.

They’re also called as foam fractionators as they work by producing an overflow of a mixture of water, air and foam. These protein skimmers remove the organic compounds before they get a chance to breakdown and murk the clarity and cleanliness of the water.

They’re called protein skimmers because they use the polarity of the amino acids to remove the various organic compounds. Now that may sound a bit too nerdy but what it basically means is, this equipment removes the food wastes and other excreta wastes in the water.

How does a protein skimmer work

Almost every protein skimmer has the same base design features. There is a chamber known as the reaction chamber through which the water from the tank flows. It is in this chamber that the water is brought into contact with a column of fine bubbles. Due to the surface tension of the water, the bubbles collect proteins and other substances like fat fatty acids, carbohydrates, metals like copper, trace elements such as iodine. Then such materials are carried to the top of the device where the foam, but not the water, collects in a cup.

Here the foam condenses to a liquid, which can be easily removed from the system. The material that gets collected in the cup can range from plain greenish yellow, watery liquid to a thick black tar.

Why do I need a protein skimmer? Advantages of having one

The benefits of using a protein skimmer are so overwhelming that it makes absolutely no sense in not using one. And that is exactly why even commercial water tanks like municipal water treatment facilities and public aquariums use protein skimmers.

What makes a protein skimmer absolutely beneficial is that it works in those intricate places where your normal filtration unit does not. They filter out organic materials such as uneaten food, excess protein and waste products before they get a chance to breakdown inside the water and pollute it.

These also help to remove the excess fatty acids, metals such as copper, trace elements such as iodine from the water and remove the unnecessary colour from the water.

This is exactly why protein skimmer becomes absolute necessity for coral reef tanks as they are quite sensitive to such organic matters.

In short,  protein skimmers help reduce the bio load in your tank, work on organic matters that the filter may have missed and elongate the time between two water changes.

It has a needle wheel impeller inside it which moves the water and combines it with air. Then, with the help of the Sicce Syncra 1.0 pump, the impeller then separates the waste from the clean water and provides the fish with a healthier environment. In many protein skimmers, this whole setup has to be bought as a separate machine, but the Aquamaxx comes with this setup.

It uses a bubble diffusion mechanism which generates a great deal of foam within the water. This form collects waste products along with left over food or other impurities in the form of the froth which is then cycled into the collection cup by the impeller. In the collection cup, it is kept separate from the fish in your tank.

Unlike the SC301,  the Aquamaxx comes with a collection cup which is quite easy to remove.

The Bubble Magnus has a SP1000 pump that is built into it’s reaction chamber. The pump being in the reaction chamber keeps it away from the other parts. However, the down side is that the SP1000 is unique to the BM 5 and if broken can be very hard to singly replace.

The bubble plate reduces any turbulence in the reaction chamber and allows for even more collection of wastes at a higher rate.

The BM 5 “Curve” gets it’s name from it’s curved body design, another unique feature to the BM 5. This shape allows the dirty foam to rise quickly.

Reef Octopus classic 110 INT Needle Wheel Protein Skimmer

On average the Reef Octopus Classic 110 INT works upon a 100-gallon tank.

When the bioload of the tank is heavy it can easily handle a 60-gallon tank and when the bioload is light, the skimmer can easily handle a tank up to 130 gallons. This makes it very suitable for larger tanks.

It is a large skimmer but for the size, it produces very little noise. And all that is due to the air intake system and also partly due to the performance-enhancing Venturi Air Injection system.

Since it is high on performance, it fills up its collection cup pretty easily. However, to solve the problem of overflowing, it has a drain system. Along with that, the collection cup is quiet easily removable and easily out back again. It makes the cleaning process hassle-free.

Despite the huge power delivery and large size it is quiet easy to control with it’s precision water level control output valve.

Apart from all these, it is made up of acrylic that makes it scratch proof and durable.

Things to consider before buying Protein Skimmers

There are tonnes of options available in the market if you want to go ahead and buy a Protein skimmer. However, you want to refrain yourself from rushing into buying a skimmer too big for your tank or one which is too small and you will have to rapidly upgrade it again.

The first and foremost thing obviously, is looking at the specifications in the packaging.  Most packages have a specification that the skimmers inside work for certain volume tanks. But, you also should consider the bioload. The heavier the bioload, meaning the more the plants and fish in the tank the lesser the gallons the skimmer will filter out.

The bioload pressure on the skimmer is also dependent upon your other filtration units. If you change your filter sockets very often it reduces the workload on the skimmer and you can buy a smaller one.

If you are a beginner, you will want to start with a smaller unit. Larger necessarily doesn’t translate to better. In fact, it may quiet produce opposite effects. Going overpowered in a smaller tank leads to zero activity in the skimmer. So it is better to be underpowered at the start than to be overpowered.

How do I setup a Protein Skimmer?

There is no hard and fast procedure for this. Every skimmer is different and is set up in a different way. Make sure you get accustomed to the parts of the device before setting it up and carefully read the manual beforehand. Also, see where the skimmer should go, whether it is a hang on a back skimmer or something else. Once you set it up, make sure it is not leaking.

How do I clean a Protein Skimmer?

Clean it at least once in six months. Replace the air tubing if necessary. Disassemble the skimmer and then soak it in hot water for an hour, scrub off the dirt and deposits and then rinse it off.

What else does it remove and what doesn’t it remove?

Salt? No.

Nitrates? If Nitrates are consumed by microalgae then yes.

Phosphates? No.

Algae? It reduces the growth of algae.

Ammonia? Only low levels of ammonia .

Calcium? Not very much.


I hope by now, we have succeeded in making you understand the ABCs of Protein Skimmers.

Personally, we here would like to suggest the Reef Octopus Classic 110-INT Needle Wheel which offers you huge amounts of features along with the necessary power and doesn’t get heavy on your budget.

However, the choice is completely on you. And every product listed above is very much competent in helping you maintain a great and healthy aquarium.
