What are protein skimmers used for in aquariums?

Protein Skimmers are additional filtering devices that are vital to successful marine aquariums. In addition to removing proteins and other organic waste materials, protein skimmers help maintain an aquarium that is happy and healthy. Protein skimmers permit the primary filter system to work more effectively and offer a myriad of advantages for better clarity and quality of water.


Protein skimmers depend on the chemical process known as adsorption that helps get rid of organic waste material out of the column. The waste materials stick onto the top of air bubbles and then are taken out of the water. A vigorous mix of water and air inside the protein skimmer reaction chamber creates thousands of these protein-skimming microbubbles. When these bubbles move through the skimmer, any waste stuck to the bubbles gets reduced and then absorbed into the cup for collecting protein from the skimmer. This process of active waste removal used by protein skimmers permits chemical, mechanical, and biological filtration to operate more effectively.

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
