Hey everyone, I'm new to the salt scene and with that being said, I'm going to have a few questions. My first one being, I am setting up a 100 gallon with a 34 gallon refugium tank; if I plan on doing a reef/fish mixed tank, what is going to be the first thing I put in it? Snails, crabs, shrimp? I'm putting 60lbs of live sand in the tank and 20lbs of Ecosystem miracle mud in the refugium. Amy advice is greatly appreciated.
