What is a Protein Skimmer?

A protein skimmer is a gadget that cleans the water in an aquarium. It does so by eliminating organic materials like excess bacteria, animal wastes, uneaten foods, and so on. The protein skimmers create bubbles that take away the compound along with it.

Also, using such skimmers you can get rid of compounds from your aquarium before they break up and cause havoc in the water. This gadget prevents algae from spreading and lowers the nitrate buildup.

So, a protein skimmer is very helpful and we also know which the best option for you is. So, why wait any further, let us dive into this SCA 301 302 303 Protein Skimmer review.

SCA Protein Skimmer Features

Nobody likes a skimmer that produces too much noise. This is something SCA understands and thus its protein skimmers come with an air silencer.

It reduces the amount of noise generated by your skimmer. To be more precise, it softens the sound that is created when air is sucked into the device to generate bubbles.

It is included in your package at no extra cost and this definitely is attractive.

Has Highly-Efficient Pump

SCA-301 has a 28-watt pump which may not seem great but is actually good enough for a small tank. Suction cups are present at the bottom that will help secure the pump to your tank’s floor.

The pump will be present underneath the skimmer’s body. Its output will jet up right into the chamber and create bubbles.

SCA-302 includes a 2000 needle impeller pump. They basically are a collection of needles that chop the tank water into little bubbles. These bubbles will trap unnecessary organic matter into your tank. Then, it will move it upwards and land it up in the collection cup.

The needle impeller makes SCA-302 highly effective and so does the Atman PH2500 needle impeller pump of SCA-303. It is more powerful than what SCA-302 offers and thus is suitable for bigger sized tanks.

Includes a Good-Sized Collection Cup

SCA-301 has a good-sized collection cup for small-sized tanks. It will require cleaning once or twice a week. But that should not be an issue because you know your tank water will be thoroughly clean always.

SCA-302 and SCA-303 both have extra-large collection cups. This will help make sure no matter how big your tank is, the collection cup will be able to collect the wastes effectively.

What is more amazing is that it is super easy to clean the collection cup of each of these models.

Easy To Assemble


A protein skimmer is absolutely essential for the good life of your fishes. You would not wish to waste any time after you get it. Rather you will want to begin using it as soon as is possible.
