AboutNick Expertise I can help with most saltwater questions, relating to stocking levels, fish care, corals, technical, lighting, set-up and maintenence in both large and small saltwater tanks. Specializing in the care of saltwater fish, I can answer nearly all questions relating to stocking, feeding, acclimating, caring for saltwater fish, as well as compatibility with other fish and invertebrate as well as a bit on corals.
Experience I have kept fish since I was 6. I care for many saltwater fish tanks and I also work in a local pet store as the manager of the fish section.

Question What is a protein skimmer and do I need one and what does it do for my tank?
Answer Protein skimmers take away rotting material before is compromises water quality. They do wonders controlling nuisance algae, diatoms, detrius...etc. They also take away that oil film on the top of tank, increases oxygen level throughout.
They are a nessecity in tanks over 30 gallons, and for tanks under, while not being mandatory, are extremely beneficial and make life so much easier.
Regardless of the tank size you have, you should try to put a skimmer on it. I have heard of a lot of large tanks without skimmers that have crashed, likely for that reason.
