2017’s Best Protein Skimmers Reviewed: Top Rated for Nano and Reef Aquariums
When caring for fish it’s important to make sure that the water quality is kept clean. So having a good aquarium filter is necessary. But what about a protein skimmer? For some aquarists a filter alone isn’t good enough. A top of the line protein skimmer is also necessary.
What Does a Protein Skimmer Do?
If you don’t already know what a protein skimmer is then the best way we could explain it is that it’s a mechanical filter that cleans your aquarium water by removing toxins, bacteria, waste and leftover food that your fish don’t eat. A good skimmer is able to stop the tank getting dirty by removing compounds before they break down. This means that algae can’t grow as fast, as well as reducing nitrate buildup that can hurt the health of the coral.
Now you may be wondering where the name comes from. The reason it is called a protein skimmer is that it removes the organic compounds by using the polarity of the protein itself. The intrinsic charge of molecules will either be repelled or attracted to the bubbles that the protein skimmer produces. So basically what happens is that the waste sticks to the bubbles and collects on the surface of the water. It then is removed from the water with the collection cup. These products not only remove protein, but also other molecules like fats, carbs, copper, iodine and fatty acids.
Types of Protein Skimmers
There are roughly four different kinds of protein skimmers that we will go over here. They all have different uses so read carefully to select the best one for your needs.
These are mainly meant for smaller fish tanks like nano tanks. They don’t take up much space so they are ideal for this purpose. Don’t be fooled by their small size, they do a great job of removing waste from your nano tank.
Hang on Back
Often referred to as HOB, these do just as the name suggests and hang off the back of your tank. It does this in a similar way to how a power filter hangs on an aquarium. They are ideal for smaller aquariums under 100 gallons, as well as ones that don’t run a sump.
Just like the name suggest these ones outside of the sump. What happens is first the sump feeds water in the protein skimmer and the skimmer expels the cleaned water back to the sump.
The largest category of skimmers is this one. There are many options available ranging from cheap to extremely high prices. They fit in the sump of the tank system.

The advantage of having the pump external of the skimmer is that there is no heat exchange with the water. It can be used on fish tanks up to 100 gallons which should be enough for most people
The build is high quality acrylic that is built to last and works great. Cleaning is a breeze too as long as you leave half a foot between the wall and the tank so you can get in there and remove the pump for regular maintenance.

We say proceed with caution as a mistake can restrict the water flow.
