This article on Marine Depot explains the science behind protein skimmers and what makes them so important to have.
Ya, I know that the chart is way to complicated. It’s basically saying that half the size of the bubble, doubles the surface area for the same volume of air. Check out the article, it’s a great read.
Protein skimmers are somewhat of a hot topic in the saltwater hobby. Many people believe that skimmers are not necessary. In fact, many hobbyists run saltwater tanks successfully without them. If you go on saltwater aquarium forms, you will see many discussions and even arguments between others debating whether or not protein skimmers are necessary.
Well, I believe they are great for all saltwater tanks, and it is one of those pieces of equipment that is worth the money and is highly recommended.

What Is A Protein Skimmer? How does it benefit your saltwater tank?
A protein skimmer is a type of mechanical filter that removes organic compounds from your aquarium water. Things like waste, uneaten foods, toxins, and bacteria are all things that a protein skimmer helps remove.
Protein skimmers are essential as they remove organic waste before they have a chance to break down and release nitrogen compounds. They also help reduce nitrate levels which is very important if you have a reef tank where low Nitrate levels must be maintained.
An advantage of using a protein skimmer is that it helps keep your water free of toxins and is a huge support to your filter system in keeping the tank clean.
They also help increase oxygen levels and overall water quality.
Before choosing a protein skimmer, you will need to decide what type you need. Are you looking for a hang on tank style or an in-sump skimmer? Both can be very effective. Of course, if you don’t have a sump tank running, then you won’t want an in-sump skimmer.
There is also an option to use an in-tank skimmer, which is great if you don’t either have a sump or space behind the tank to add a hang-on style.
Also, keep in mind that you will need to choose a proper size skimmer that is best suited for your tank. It’s best to choose a skimmer that is rated slightly higher than your tank size.
For example, if your tank is a 75 gallon, then you might want to choose a skimmer that is rated for up to 100 gallons.
Before I show you my picks for the best protein skimmers, I want to mention the cost. Depending on your budget, there are many options available to you.
While some skimmers can be very expensive, you can still get a great skimmer on a budget. The ones I will show you here, are the most commonly used and affordable options for most hobbyists.
I don’t recommend buying the cheapest skimmer either, as you will be disappointed by its performance and they are not worth getting.
Types Of Protein Skimmers
The most commonly used types of skimmers today are:
- Hang On Back (HOB) Style
- In Sump Style
Other types include:
- In-Tank Style
- External Style
In this article, we will cover the 2 most commonly used types of protein skimmers. The Hang on back (HOB) and In sump styles.
Hang On Tank Protein Skimmers
HOB or hang on back protein skimmers as the name states are designed to hang off the back of your tank using the tank’s trim. The manufacturer of the skimmer will provide you with the clip, bracket, and anything else needed to fit it onto your tank. These skimmers are very effective, easy to use, and convenient. But a downfall of them is they require space behind your tank and can be an eyesore depending on the type you choose.

The AquaMaxx HOB 1.5 skimmer is designed to be efficient and powerful. This model is an upgrade from the AquaMaxx HOB 1. It is more powerful and includes a larger bubble diffuser and reactor chamber.

If you have a tank with a heavy bioload, I recommend a maximum tank size of 60-75 gallons.
Combine that with an efficient and upgraded Shark pump and you have yourself a skimmer that is powerful and does a fantastic job. Some hang on tank protein skimmers can be bulky and an eyesore, but the AquaMaxx is just the opposite. Its slim design is light, easy to fit in reduced spaces, and looks good.

In Sump Protein Skimmers
In sump protein skimmers are meant to be used in saltwater aquariums using a sump tank. These are meant to sit inside the sump skimmer chamber at a certain water level depending on the skimmer you are using.
Sump chambers can be different sizes so it’s important to not only purchase a skimmer that is sized correctly for your tank but sized to fit your sump as well.
There are many benefits to having an in-sump protein skimmer. One being that it will be hidden within your aquarium stand so you won’t see cords and equipment hanging off the back of your tank. Some larger tanks will require a very large skimmer which hanging off the back of your tank is not possible or ideal.
Another advantage is in the event of a skimmer cup overflowing, it will simply flow back into your sump tank and not all over your floor which is possible with a HOB skimmer. These are just a couple of advantages to an in-sump protein skimmer. If you have the option of using a sump system on your aquarium, I highly recommend you do so and incorporate an in-sump skimmer.
1. Bubble Magus Curve 5
The Bubble Magus Curve 5 protein skimmer has been a popular choice for many hobbyists. I have used this skimmer with success for many years. Bubble Magus produces practical and efficient skimmers that work well and perform great. The parts of the skimmer are highly durable and will last a long time.
Although it’s not the most compact skimmer in the world, it will fit your sump nicely. If you have a medium-sized tank up to 140 gallons, this skimmer will perform well for you. It incorporates a needle wheel design that produces very fine micro bubbles, therefore, increasing its performance.
The curved body style allows the foam to easily rise to the collection cup for removal.
Other features include silent air intake, accurate height control, drain cup, and stylish design. The Curve 5 is very affordable and provides excellent quality for the cost.

The Simplicity 120 DC skimmer is another great skimmer even if you are on a budget. They are designed to be reliable, efficient, and provide great value. The hybrid cone design allows for more contact time which is essential for performance.
Another great feature is the custom control over the amount of air entering the chamber. You can fine-tune it for optimal performance using the adjustable air intake dial.

The Simplicity 120 DC skimmer is very easy to perform maintenance on and clean. It incorporates a thumbscrew assembly which makes it easy to dissemble. The large collection cup and built-in drain is also a bonus.

As you can see, choosing a protein skimmer for your tank involves looking at all the variables of each one. I always recommend that you choose a skimmer that is rated for your tank size or slightly oversized. You will notice that most manufacturers will specify the maximum tank size that the skimmer is rated for. Keep in mind this rating is based on a light bioload.
So depending on the livestock you have, the ratings can vary. Even though a skimmer may be rated for 150 gallons, it may be more efficient on a tank with a medium-heavy bioload of 75-100 gallons.
After weighing all the options, choose the one that will work best for your tank. All tanks are different. You can’t go wrong with any of the above-mentioned skimmers. They are all proven to great skimmers!
