16 Best Protein Skimmers: Features, Pros and Cons

A great protein skimmer is integral if you want to keep your aquarium clean and healthy. 

As time goes on, unwanted organic materials like uneaten food, fish waste, and bacteria will collect in the water of your tank. Nitrate levels will also increase, and the water will become cloudy. 

If you don’t keep your water clean, the overall health of your aquarium and its inhabitants will be compromised. The aquatic life you raise can be vulnerable to nitrate, and living in an environment filled with small debris, particles, and murky water will result in severe problems later. 

This is where a protein skimmer comes in handy. The below article will list the best protein skimmers available on the market, as well as their pros and cons, helping you choose the right one. 

What is a Protein Skimmer?

A protein skimmer is a kind of mechanical filter that clears organic materials out of the water in your fish tank. That consists of excess toxins and bacteria from corals, waste products from your critters, and even uneaten food. 

A protein skimmer is to remove the organic compounds before they break down and affect the cleanliness and transparence of your aquarium water. This device can prevent algae from developing too fast and decrease the nitrate buildup that can endanger some marine species like corals. 

It is called a protein skimmer as it employs the polarity of the proteins to eliminate the different organic compounds.

How Does it Work?

As mentioned above, the protein skimmer uses the polarity of the proteins to clear them away from the water column. 

It involves a reaction chamber where it produces a number of tiny bubbles. Due to the properties of the protein in the organic compounds, the organic waste materials will adhere to the bubbles. Then, the bubbles bring these materials up to the surface of the chamber, where the contaminators can be manually eliminated from the water column via the collection cup. 

In some models, you might get needle wheel or pinwheel impellers in the skimmer pump, which then splits the incoming bubbles into smaller ones. Smaller ones are more efficient than larger ones. This is because they have more surface area for the compounds to stick to. A high amount of small bubbles is recommended. 

Types of Protein Skimmers 

There are multiple types of protein skimmers designed according to specific purposes. Make sure you have a deep understanding of your tank and what it can accommodate before squeezing the trigger and selecting one. 

Hang on Back (HOB) Skimmers 

A hang-on-back protein skimmer is a device hanging on the back or rim of the tank glass. It’s suitable for aquariums that don’t run a sump. This type will fit small tanks that don’t go past 100 gallons in capacity. 

In-Sump Skimmers

This type lets your aquarium remains to look tidy and neat while the skimmer works in the back room. As long as you have a sump, there is a variety of in-sump protein skimmers options for you to choose from. 

In-Tank Skimmers

These skimmers are meant for nano aquariums, so they don’t require much space inside the tank. Despite their size, the in-tank skimmer models will do a good job of clearing organic compounds in the water. 

External Skimmers 

This kind of skimmer draws water from the aquarium, passes it via the system, and then pumps the purified water back into the tank. 

External skimmers can be beneficial if your aquarium setup does not have enough room for a skimmer to stay inside.
