my tank is about ready to go. it is a 100 gallon setup w/ 40gallon refuge with lr and ls... is the clean up crew the next step? and if so.. what do i need? i want to make it a reef tank (xenia, red mushrooms and clown fish, tangs, goby and angels).. if i left out details that are needed let me know, i'm really new to saltwater. thank you in advanced
