Protein skimmers also help increase the dissolved oxygen levels in
your saltwater aquarium.

It is an external filtering tank, not used most of the time because
external mechanical filters are much better compared to this.
Aquarium Sump
Sump is like an external tank with the provision to filter out the
waste from the main tank. This sump is not used these days because
you can see how that is going to increase the maintenance.
