Best Protein Skimmer | 2022 Guide

Even the most experienced aquarist can struggle to keep the water in their tanks clean and free of unwanted impurities. It’s incredibly easy for organic compounds to build up in aquarium water which, left unchecked, can eventually dissolve. When these compounds break down and become solvent, they can massively impact the quality of your tank water. This not only leads to less than ideal conditions for your fish and plants, it also impairs the viewing experience of aquarium owners.

While filtration systems go some way to keep tank water clean and free of impurities, they are not completely effective. A protein skimmer is often called for if you want to remove as much organic material as possible from your aquarium before it has a chance to dissolve and cause you more serious issues. Below, we will explore the key things you should be focusing on when choosing the best protein skimmer for your aquarium.

Protein Skimmers Explained

A protein skimmer is essentially a form of mechanical filter. Protein skimmers remove large particles of organic material from the water within your fish tank. This material could include waste toxins or substantial bacterial growth. It can also be residual food particles, as well as faecal matter produced by your fish. A protein skimmer serves as an effective solution for getting rid of this excess material before it dissolves and has a significant effect on aquarium water. Nitrate build-up and algae growth are just two of the things that can be kept in check by utilising a protein skimmer.

A protein skimmer has something called a reaction chamber, with this element producing a large amount of micro bubbles. These bubbles attract organic compounds in proteins, with the material adhering to the surface of these tiny bubbles. When the bubbles rise to the surface, they burst, distributing the previously attached organic material to the surface. This material can then be easily removed from your tank via a collection cup. The best protein skimmers also make use of needle wheel attachments and impellers that cut down produced bubbles into even tinier bubbles. A greater number of micro bubbles allows for even better capture and retrieval of organic compounds.

Protein Skimmer Varieties

Although most protein skimmers fulfil the same task, they come in a variety of different types. Hang on back (or HOB) skimmers are among the most popular. If your tank doesn’t include a sump as part of its design, a HOB protein skimmer is without doubt the best option available to you. These protein skimmers can be hung on the side of your tank, much like a power filter. Although effective, HOB protein skimmers are better suited to smaller tanks. If you have an aquarium with a capacity of 90 gallons or more, a HOB protein skimmer is unlikely to be fit for purpose.

Alternatively, you can consider a submersible protein skimmer that can be placed directly in your tank. These protein skimmers tend to be on the small side, making them suitable for even the most compact of tanks. If you have a tank that houses nano fish varieties, an in-tank protein skimmer is an effective option.

In sump protein skimmers are another worthwhile option. As the name would suggest, these protein skimmers are designed to be housed within aquarium sumps. You tend to find more model varieties when dealing with in sump protein skimmers. If you have a particularly large tank, an in sump protein skimmer is a good choice. These protein skimmers are not only effective, they are also fairly affordable. However, overall asking price will vary, depending on the individual features of any given protein skimmer.

Finally, you have external protein skimmers to consider. These protein skimmers are placed outside of your tank, with water being fed into the protein skimmer via the sump. When the skimmer has cleaned your tank water, it is then returned to the sump, which in turn forces skimmed water back into your aquarium.

Is a Protein Skimmer Essential?

Not every aquarist will need a protein skimmer, but there are some situations when such devices are essential. For saltwater tank scenarios, a protein skimmer is a must. Those aquarists who have coral housed in their tanks will almost certainly require a protein skimmer. You may also find a protein skimmer essential if you have a large stock of fish species that rely on a carnivorous diet. Ultimately, if you are experiencing high levels of nitrates and ammonia in your tank water, there is a real need for a protein skimmer.

Although protein skimmers are a crucial part of saltwater aquarium setups, they are also regularly used by owners of freshwater tanks. If your current filter system is struggling to keep on top of water quality and water clarity is suffering, a skimmer can serve as a helpful secondary support for your filtration system.

Protein Skimmer Benefits

The main benefit of a protein skimmer is that you will face less hassle in trying to maintain clean water conditions. They also provide an effective way of keeping toxicity low. If you are stocking your tank with large fish species or coral varieties, installing a protein skimmer will reduce the amount of painstaking maintenance required to keep such specimens healthy. If you are keeping any kind of species, be it plant or animal, that will suffer ill effects to even the slightest spike in nitrate levels, a protein skimmer is an essential purchase.

A protein skimmer will also help your filtration system perform optimally. Many aquarists find that, even with careful tank maintenance and regular filter cleaning, their filter systems are constantly pushed to their limits. With a protein skimmer working alongside it, your filtration system can focus on doing its job. By having the two systems working in tandem, you will not have to worry too much about manually retrieving excess food, or carrying out constant cleaning of your aquarium accessories.

A skimmer will keep on top of the nitrates and protein-rich waste such specimens produce. Freshwater aquariums can also benefit from a protein skimmer, especially if you struggle with overfeeding, or you have a large tank that is stocked with a large fish population.

When choosing your protein skimmer, consider the practicality of each main model type. If you want something convenient and easy to install, opt for a hang on back protein skimmer. If you only have a nano tank, a submersible model that can be installed directly in the tank is arguably your best option. For larger tanks, in sump protein skimmers and external skimmers are undoubtedly the best option.
