How does a protein skimmer work
The skimmer pump produces air bubbles that proteins and waste attach to inside the skimmer. The result is that the air bubbles carry waste to the top of the skimmer and spill into a collection cup. The pump is the heart of the protein skimmer as they produce the waste carrying air bubbles.
Good protein skimmers often include a needle wheel impeller which will chop incoming air into even smaller bubbles.
As bubbles pass through the impeller needles or pins the impeller shreds incoming bubbles into microbubbles. A high-quality pump with a well-designed impeller will produce more bubbles that are smaller in size which increases the surface area inside the skimmer to remove more waste. Also, a high-quality pump will last longer and also run quieter.
Size of the skimmer reaction chamber.
The reaction chamber is part of the skimmer body where all the magic happens. A big reaction chamber allows for a larger volume of air bubbles to accumulate and attract proteins. Furthermore, it also allows for more contact time for the bubbles to attach to proteins. The shape of the skimmer body shouldn't be overlooked either. This is because as a smooth transition from the skimmer body to the collection cup is what allows the bubbles to easily rise and fall into the collection cup for easy removal.
The main three types of body shape are cone, hybrid cone, and wineglass.
These offer the smoothest path for air bubbles to rise into the collection cup with the least resistance.
When looking for the best protein skimmer ,an easy to use and responsive outlet adjustment is also helpful because it allows you to adjust the water level in the skimmer. You can easily fine tune the skimmer for steady skimming production and to avoid overflows.
Many of the newer best protein skimmers include bubble plates which reduce turbulence. the result of this is that is it further increase contact time an air silencer and a collection cup with drain fitting is very useful.

Another advantage is they have more contact time due to the design of recirculating that means it will produce increased skimmate. Also, you don't have to worry about any depth of water like a skimmer that sits in a sump they need to be in a certain depth to run smoothly. With a recirculating skimmer, you don't need to worry about that as the skimmer is fed via a pump.
