I am in the middle of a new build: 120 gallon (approx 30x30x30) corner cube. I currently have a 30 gallon sump, and was planning on using a good protein skimmer and pump to get 12gph exchange. I've heard good and bad about refugiums. Should I or should i not use one? What are some cost, time, maintenance, benefits etc. differences? Thanks for your input.
