A Protein skimmer is essential for a marine aquarium, as it reduces the organic waste that is built up over time in a marine aquarium and sits in the sump of your aquarium. You need to place water in the sump first before adding the protein skimmer so it can fill up with water. Allow to run with the lid open for 3-4 days as a break in period and check the collection cup daily.
