What Is A Protein Skimmer Used For?

A protein skimmer, sometimes known as a foam fractionator, is a mechanical device used to remove waste materials (organic) from seawater. They are of high benefit to maintaining water quality in marine aquariums ensuring clear water, more efficient biological filtration, and improved oxygen levels.

How Do Protein Skimmers Work?

A protein skimmer works by pushing high volumes of air into your aquariums water column causing bubbles to form. These bubbles then attract gunk and waste material to stick to them before rising to the surface.

Once at the surface the bubbles become foam (skimmate) which is pushed up the neck of the protein skimmer. There the bubbles/foam burst and the waste material is trapped in a collection cup or waste line to be discarded.

  • High performance pump included
  • Tanks up to 140 gallons
  • SP1000 internal pump
  • Slim DesignnPerfect for 6-7 inch of sump waternPricenGood size collection cupnWorks really wellnn
  • Drain hole in collection cup not able to block offnInstructions not clearnWattage variednn

This internal protein skimmer is practical and highly efficient. Its features include a needle wheel pump that ensures just the right amount and size of the air bubbles. It also works quietly thanks to its air silencer and smooth operation design, whilst its quick-release collection cup provides ease of cleaning.

Despite loving this protein skimmer, in general, I did have one or two teething problems. I found it difficult, for example, to adjust it to my water levels, and for this reason, had it going bananas for a week or two. However, once broken in, it performed to a very high standard and I realized I just needed patience.

Cleaning the Bubble Magus proved to be a breeze. I took it apart, cleaned it, and put it back together in no time at all. Just be aware, however, that after cleaning this unit, it will need time to stabilize again.

  • Dimensions: L 7.5 x W 3.5 x H 17 Inch
  • Minimum tank height 10-7/8"
  • Requires approximately 4" of clearance to remove collection cup.
  • Fits aquarium rims up to 3/4" thick.
  • Easy setupnEasy to cleannVery big collection cupnBox design fits more aquariumsnStrong and quiet pumpn
  • Costn

This HOB protein skimmer was incredibly easy to install and to get running smoothly. It worked hard just hours after being put into my aquarium and has continued to do so ever since. Surprisingly, it is also very quiet for a protein skimmer that works so well, only giving off a faint rumbling – easy to ignore.

On the downside, the air intake does need regular cleaning to rid it of mineral deposits. I found that soaking it in white vinegar every couple of months sufficed. The hanging bracket is also not adjustable so I did have some inconvenience of having to cut the rim in order to hang it.

  • New pinwheel impellers provide up to 100% improved performance

  • A little noisynInstructions not clearnn

Taking less than 24 hours to start skimming efficiently and being ‘plug and go’, this protein skimmer has a lot going for it. It is easy to clean, has pinwheel impellers improving performance, and gate valves to allow easier water level adjustment.

Over the time I tested this product, I found it to be highly effective in cleaning all the gunk out of my aquarium. It did, however, need its collection cup and neck cleaned once a week. This, nonetheless, really was a non-issue as Reef Octopus could not have made cleaning this unit simpler.

  • Patented needle wheel aspiration system
  • Wide neck collection cup with easy twist feature for effortless cleaning
  • Dual injection inlets increase bubble/water contact time
  • Bubble production diffuser to prevent the flow of micro-bubbles into main aquarium
  • Can be used in sump or with hang on mounting bracket
  • Once setup worked wellnPricenLooks goodnQuietnDry u0026 Wet Skimn
  • Not very powerfulnDifficult to assemblen

The first thing I have to say is that not only does this skimmer look like something from an alien spacecraft, but so does its instructions. They were not clear at all, though that could just be me being a little dumb, and it took me quite a while to figure it all out.

Once I had it up and running, however, this skimmer worked like a dream. I tried it both ways that you can, in the sump or on a mounting bracket, and it performed both ways just fine. It doesn’t leak, there’s no mess, and I never had to fight with it. Cleaning was also simple and quick to perform, but as with the others, needs doing regularly.

  • They are built with high quality acrylic
  • PricenSize and compatibility nVery QuietnEasy to installnGood HOB skimmernSuitable for all size aquariumsnnn
  • Difficult to cleannCollection cup seal poor

With very easy instruction and arriving partly assembled I found this skimmer a breeze to install. It even, if you choose to make use of it, has a great instructional video available online.

Once installed, I found this unit quite attractive and space-saving with its pump being located on the outside of the aquarium. It did, however, take quite a while to become efficient. Once working fully, nonetheless, it did exactly what it says on the tin. It cleaned the gunk from my aquarium and it did it very quietly.

Most modern saltwater refugia have a protein skimmer

Types Of Protein Skimmer

There are four types of protein skimmers to choose from as listed below. Which one you choose should be based upon what works for you, and suits your needs best.

In Sump Protein Skimmer

Sumps work by acting as a reservoir to circulate and clean water. They are an excellent place to hide a protein skimmer if you don’t like your equipment on display. Most modern reef aquariums have a sump tank and protein skimmers built inside the refugium.

External Protein Skimmer

Designed to be housed in the aquarium, the external protein skimmer works in the same as the ‘in sump’. They feed clean water back to the sump before it is returned to the tank.

Hang On Protein Skimmer

Commonly referred to as a HOB skimmer, this type can be hung on the back of your aquarium making it compact and easy to fit. They are usually purchased with brackets to help you attach it.

This type of protein skimmer is often used in nano reef aquariums where the tank size is limited.

In-Tank Protein Skimmers

Mounted inside the aquarium, this type of skimmer ends worries about wet floors. However, they do take up a lot of space in your tank making them difficult to disguise.

Protein Skimmer F.A.Q

  • What is the purpose of a protein skimmer? Protein skimmers are used to help maintain low nitrate levels by holding back nitrate buildup.
  • Do I need a protein skimmer? Though protein skimmers aid enormously in helping to keep an aquarium clean, they are not an actual necessity. However, if you plan to keep complex corals and fish, they are a very good idea.
  • Is a protein skimmer the same as a filter? No, a protein skimmer removes waste before it breaks down, a filter does not.
  • Can you use a protein skimmer in a freshwater aquarium? Yes, but they are not as effective.
  • Does a protein skimmer oxygenate the water? Yes, although they are nowhere near as efficient as powerheads or water pumps, at creating water movement in the aquarium.

What’s the best protein skimmer and the winner from our review?

Overall, I found the AquaMaxx HOB skimmer to be the pick of the bunch. This is not only due to its efficient performance and ease of use but also due to it being a HOB unit. After all, not all saltwater aquariums have a sump to place their protein skimmer in meaning only a HOB skimmer is suitable for all.

Conclusion: Top 5 Protein Skimmers Perfect For Beginners

It has to be said that whilst the protein skimmer may not be essential, in all cases, it is certainly of the highest benefit having one and a good idea to at least seriously consider them.

After all, they boost the cleaning of your aquarium far beyond what a filter alone is capable of and do so easily and efficiently.

My nano reef aquarium would not be the same if I didn’t have a protein skimmer attached. Read our TOP NANO REEF FISH LIST for details of what fish are best for smaller saltwater aquarium.
