Best Protein Skimmer Reviews – A 2024 Buyer’s Guide

If you’re a saltwater aquarium hobbyist or on your way to becoming one, you may have heard how vital a protein skimmer is to maintain your aquarium. A protein skimmer works by filtering unwanted solid particles in the water, thereby making the water safe for the tank’s fishes.

Protein skimmers have now been modified for domestic use as more people have embraced home aquariums. This article will cover:

  • the importance of protein skimmers,
  • the types of protein skimmers,
  • and the best protein skimmers available on the market.

What is a Protein Skimmer?

A protein skimmer is simply a mechanical device that removes all kinds of organic compounds, including protein and amino acids found in food particles from your aquarium. Protein skimmers are specially designed to replicate the natural filtration that occurs in the ocean, where waves carry organic compounds attached to it to the shore.

A protein skimmer follows a general working principle. Water comes into the system through a chamber and mixes with air bubbles. The polarity of proteins and other organic compounds will cause them to attach themselves to the air bubbles. Together with the organic substances attached to them, the bubbles will rise to the water’s surface as foam.

The foam-filled with organic waste called skimmate is then forced into the protein skimmer and held in a collection cup, which acts as a storage place until the wastes condense. When the foam in the collection cup finally condenses to a liquid that could be a pale greenish-yellow liquid or a thick black tar, It can now be discarded.

The video below shows in detail how a protein skimmer works with a reef tank.

Types Of Protein Skimmers

Most times, people who need a protein skimmer cannot equip themselves with the right information before placing an order. This is partly due to marketers’ inadequacy of information about protein skimmers, reducing the means for sites to produce helpful information.

Keep reading to know more about the different types of protein skimmers available and what type of aquarium they are best suited for.

Internal Protein Skimmers

Internal protein skimmers are skimmers that are mounted inside the tank. They don’t boast of high-performance, so for you to fully enjoy one, make sure you settle for a highly efficient product. Internal protein skimmers are fairly easy to install, and they are free of water leaks. This type of skimmer is suitable for home saltwater aquariums.

External Protein Skimmers

External Protein skimmers are a kind of skimmers that are not mounted inside the aquarium water but are kept outside the water. This type of skimmer also uses the principle of air bubbles to remove wastes from the water. External protein skimmers are usually much larger than internal protein skimmers. They are designed mainly for use in a commercial capacity like in the treatment of municipal water and large public aquariums where up to 300 gallons of water needs to be purified.

In Sump Protein Skimmers

An In Sump protein skimmer is a type of skimmer mounted on a separate compartment in the aquarium built specifically for that purpose. Most of the best protein skimmers fall into In Sump category. The Sump can be found below, behind, and in very rare cases, it can be kept on a stand above the aquarium.

Hang On Back Protein Skimmers (HOB Protein Skimmers)

The hang on back protein skimmer is designed to hang on the back of the aquarium. This type of skimmer does not need to be mounted inside the aquarium or need to have a separate compartment built solely to accommodate it. The hang on back skimmer is a powerful filtration device, and the filtration it provides can be regarded as the strongest among the types of skimmers we have. The Hang on back skimmer features a powerful pump, a massive reaction chamber, and an air silencer working together to make your aquarium look better.

Do You Need A Protein Skimmer?

If you are a beginner who just wants to keep a fish nano tank, you might skip owning one. Learn more about the best nano reef tanks in this article.
