Guide to Buying the Best Protein Skimmer for 150 Gallon Tanks in 2019

Best aquarium set-ups require complete parts and devices. Aside from CO2 regulators or UV lights, among the important units that you should have along with your aquarium is a protein skimmer. This is also called a foam fractionator whose purpose is the removal of any organic compounds (e.g. food, waste products) in the water to make the tank cleaner and healthier for its inhabitants.

Like any other products, there are different protein skimmers available, each with varying parts. With this, you would need several options of protein skimmers to know which would really fit your aquarium set-up. More generally, you would also want to know the importance of having a protein skimmer and the factors you need to consider shall you decide to purchase one.

In this article, you will read all the best protein skimmers for 150-gallon tanks you can choose from and, more importantly, you will discover the importance of such products and several tips in choosing.

Benefits of a Protein Skimmer

Before knowing the benefits of having a protein skimmer, it would be important to know what a protein skimmer is. If you want to maintain the cleanliness of your aquarium, you would need a protein skimmer. What this product does is removing and filtering all types of waste products like uneaten food or bacteria that could affect the quality of the water.

Now, how does this product work? A protein skimmer is called as such because its reaction chamber could produce a lot of small bubbles to which organic waste materials could stick. When bubbles move and accumulate to the surface, these waste materials are brought up and could then be removed manually through the collection cup. However, proteins are not the only things a protein skimmer could remove. It can also remove other organic and inorganic molecules like fatty acids, carbohydrates, copper, and other traces of iodine. Along with this, some harmful elements like bacteria, phytoplankton, and detritus may also be eliminated.

Protein skimmer does mechanical filtering and could clean compounds before they even break down because if they do, the clarity and cleanliness of the tank water would entirely be compromised. Once they also break down, it would be more difficult to clean them, which further necessitates a protein skimmer.

Also, one important benefit of a protein skimmer is that it could quickly prevent algae from growing and it could also minimize the buildup of nitrates which would be harmful to water species like corals. By clearing the water, light could penetrate more and plants could photosynthesize properly. Also, UV lights that could kill organisms require clearer and cleaner water. A protein skimmer could help achieve this clarity.

Factors to Consider in Choosing the Best Protein Skimmer

While all protein skimmers share the same features – a chamber that allows water flow to bring into contact with several fine bubbles – there are still key functions that need to be noted in choosing the best protein skimmer.

Here are some of the requirements needed to assure a maximum protein skimmer function:

  • Generation of a large amount of water or air interface
  • Collection of organic molecules at the air or water interface
  • Formation of form by the bubbles
  • Partial draining of foam in the water must happen without the bubble having to pop prematurely
  • Separation of drained foam from the water

Protein skimmer design types are separated into four:

  • Hang-on-back protein skimmer – this protein skimmer simply hangs on the back of your aquarium unit. If your tank does not run a sump, then this type of skimmer is ideal for you. Hanging on the rim of the aquarium as the power filter does, this type of protein skimmer is particularly suitable for smaller aquariums whose capacity does not exceed 100 gallons.
  • In-tank – unlike hang-on-back protein skimmers, in-tank skimmers are not external. Small and compact, these types of protein skimmer do not really take too much space when placed inside the aquarium. Despite their small size, however, small in-tank protein skimmers do just as great job in cleaning harmful compounds in the water.
  • In sump – aquarium sumps would best fit this type of protein skimmer. Compared to other designs of a protein skimmer, this design gives you more freedom in deciding for its size and cost (and sometimes other features). This is, then, relatively more flexible.

In addition, types of protein skimmer are generally categorized into two: counter-current flow and co-current flow. For counter-current flow, air is moving against the water flow after having been forced into the system that is under pressure. For co-current flow, on the other hand, air is at the chamber’s bottom and would be in contact with the water when it rises towards the collection chamber.

These are the types of co-current flow systems:

  • Air Stone – made out of porous stones or limestones, this device slowly diffuses air into the tank. Its production of a large number of small bubbles would help in cleaning the water.
  • Venturi – Venturi pumps, also called aspirators, is another method of producing tiny bubbles. It is more compact and highly efficient compared to other designs.

These are the types of counter-current flow systems:

  • Aspirating skimmer – with the use of needle-wheels, air and water are disintegrated effectively into very small bubbles. This would result in more and finer bubbles, leading to more effective cleaning.
  • Downdraft skimmer – this mechanism uses tubes in which high water pressure is injected to generate foams and bubbles. These foams and bubbles will be collected in the collection cup. This model is relatively larger and is used in larger aquariums.
  • Beckett skimmer – although quite similar to downdraft skimmers. It also introduces small bubbles through tubes, but it is much larger and could produce more noise.

After getting an idea about the advantages of purchasing a protein skimmer and the different considerations you should have shall you decide to choose one, let us take a look at several options that you have.

Here are the best protein skimmers, with reviews and comparisons:
