What Is a Protein Skimmer?
All you probably know about protein skimmers now is that they function to make the water that your fish are in much cleaner and clearer. To distinguish it from other types of skimmers out there, let’s have a look at what a protein skimmer really is.
Protein skimmers are basically equipment that functions to purify the water in your reef aquariums by eliminating impurities such as excess bacteria, toxins from corals, waste products and uneaten food. Another key function of a protein skimmer is the prevention of algae growth in the sense that it removes organic compounds way before they can compromise the clarity of the water.
So, how does it work?
Protein skimmers basically use the polarity of proteins or rather foam factorization to eliminate impurities by creating scrubbing bubbles.
The skimmer normally has got a reaction chamber in which tiny bubbles are created. Due to the way protein acts on organic compounds, the organic waste sticks on the bubbles which then rise to the water surface from where they are manually removed from the water column through a collection cup.
Types of Protein Skimmers Available In the Market
Now that you have an idea of how it works, let’s go ahead and take a look at the common types you could come across. Here goes…
Hang On Back (HOB) Protein Skimmers
Otherwise known as the hang-on-back protein skimmers, these simply hang at the back of the aquarium. In order to do this, it uses brackets that come with it from the manufacturer.
They are best recommended for use on smaller aquariums that have a capacity that’s less than 100 gallons.
In-Sump Protein Skimmers
Looking for a good way to clean water in your aquarium without exposing the skimmer? This is it. It basically serves as a reservoir for circulating and cleaning the water at the same time. For those who don’t want additional equipment on the aquarium, this should do the trick
External Protein Skimmers
As the name suggests, they are housed outside of the aquarium and work by feeding the cleaned water right into the aquarium sump and the cycle continues
In-tank Protein Skimmers
Want the perfect protein skimmer for a nano tank? This is definitely what you should go for. They don’t take up a lot of space inside the aquarium and despite being quite compact in size, they are really effective in eliminating organic compounds from the water.
Benefits of Using a Protein Skimmer
So, what do you really get out of using either of the above-mentioned protein skimmers? Let’s have a look at the benefits of adding one of these to your aquarium, shall we?
- Balancing the pH levels– with the introduction of organic components to the aquarium, the pH level may be unfavourable for the thriving of fish. Since a protein skimmer functions to eliminate such contaminants, the pH levels are restored back to what’s favourable
- Utmost light penetration- cloudy water would mean that light penetration will be compromised. When this occurs, the plants in the water would not get as much water as is needed hence making it difficult for them to synthesize food and in the long run, there’ll be an imbalance in the ecosystem.
- Preventing the spread of algae- as it turns out, the presence of nitrates in the aquarium means that there’ll be a wider spread of algae. With a skimmer present, the nitrates are broken down and as such, the spread of algae is minimized or prevented.
- Fully oxygenated water- yet another benefit you get from using a protein skimmer is that excess contaminants are eliminated. When this happens, the level of oxygen in the water is restored back to normal and as such, your fish get enough oxygen to thrive in.
- Overall improvement of marine health- last but not least, there’ll be an overall improvement in marine health once you decide to get a protein skimmer. In order to ensure that the water is in the healthiest state, all you got to do is replace the skimmer just in case it stops producing skimmate.

The Ultimate Guide to Getting The Best Protein Skimmer
On to the second section of our reviews, let’s go ahead and have a look at all the important factors you need to take into consideration when shopping for the best protein skimmer.
The Overall Design
It’s all about efficiency when it comes to the design and as much as the end result is similar, there are different ways as to how the results are achieved. Here goes
Despite being the cheapest, they are a little too loud and the bubbles you get from these are relatively large which is not really good as far as efficiency is concerned.
With such, the skimmer is paired with a pump which then creates air bubbles and upon doing so results to the skimmer functioning as it should. A venturi is basically a valve designed to suck in air.
With such a design, bubbles are pumped via a needle wheel or pinwheel impellers. Once they get through either of these, the bubbles are then sliced to much smaller sizes hence improving the efficiency of the skimmer. For the best performance, it’s recommended that you go for one that has been paired up with a venturi valve.
The Size of Your Tank
Above all else, the size of your tank is quite important since every skimmer has got a different tank size rating. This is normally dependent on the amount of skimmate they’ll be able to eliminate from the water, the pump size and the manufacturer’s design among other things.
It’s recommended that you go for a skimmer whose rating is a little bit higher than the size of your tank since going for a smaller one will have you struggling to keep the nutrient levels down.
Being the easiest way ever for how you could get an ideal product, the same holds for the protein skimmers. Some of the brands I’d recommend you check out include Coralife, Bubble Mangus, Reef Octopus, Vertex and Aquamaxx. Picking out either of these will ensure you get both longevity and efficiency altogether
Size of The Skimmer
Something else you’ll want to pay attention to is the skimmer’s size. Regarding this, it all comes down to mostly whether or not you have enough clearance to operate the skimmer and most importantly to get the collection cup off when need be.
The Installation Location
Just as it is important to pay attention to the size of the protein skimmer, it’s equally as important to know where you’ll be setting it up. For a HOB design, you can use it on pretty much any aquarium. The sump design, on the other hand, is recommended if you have a sump and the external one is demanding more space and needs to be installed outside the aquarium.
How to Set Up a Protein Skimmer
Setting up a protein skimmer could be a little tricky. Nonetheless, here’s a guide on how you could do this with ease.
- First off, go ahead and pick one that’s got a slightly higher rating than what your tank is rated at.
- The next thing you’ll want to do is do prior assembly when need be. Be sure to check the instruction manual to know whether it’s necessary to do this.
- Once assembled, you’ll want to connect an external sump if none is provided out of the box and then connect both the inlet and outlet hoses to it after which you should plug it in to ensure the water circulates.
- The next thing you’ll want to do is hook the skimmer up at the correct depth of water as recommended by the manufacturer.
- Next, allow the skimmer to fill up with water once placed in the sump then plug it into an electrical outlet and turn it on at which point foam should be produced after a few seconds.
How to Maintain a Protein Skimmer
Truth be told, these could be the dirtiest equipment you could be using on your tank and as such, utmost maintenance is recommended. Here’s the best way to go about this…
The collection cup
Regarding the size of the accumulated bioload, clean the collection cup thrice or twice a week or less than this if the water is cleaner. This should be done by simply rinsing the cup and wiping it with a pad.
The body of the skimmer
Worst case scenario, algae could grow in the body which could be harder to clean. For normal accumulation, cleaning should be bi-annually. To get started on this, drain all the water from the skimmer and remove the sump which you should soak in a bucket with water and vinegar till the algae are easy enough to wipe away.
Once ready, clean the body inside and outside then rinse with fresh water after which you should replace it in your tank. Be sure to check algae or deposit accumulation on other parts of the skimmer add-ons and clean them just the same way.
Well, there you have it, I’m pretty sure that using, choosing and setting up a protein skimmer is much easier even if it’s your first time. A piece of advice to anyone that’s getting started, the trick is always to observe the outlined maintenance tips and most importantly, be sure to choose one while paying attention to the size rating for your tank; this way, you’re guaranteed to get a bang for your buck.
