I am starting a new mainly SPS reef tank and I have a Refugium in my sump and this is my first one so I am looking for input on what to put in it. I know I want to grow chaeto but not sure if I should add rock or sand or anything else. My DT is 75 gallons and I will have about 40 pounds of live rock and a shallow sand bed.
Thanks for your help!
