Coralife Biocube 29 Refugium

[flarpsodge4442]

Hello all! I'm brand new to this forum and would like to say hello to everyone! I am a full blown reef noob, but this site's forums have helped me a whole lot! Thank you in advance to anyone willing to deal with my extreme noobness! Well, I have a 29g Biocube PC which I just received some InTank filter mods for today. I got both the media tray and the refugium chamber, and had a few questions on it. I have bought some Chaetomorpha algae for it and have a submersible light for it, but am wondering what else I should stock it with. I have no idea what microorganisms would really be suitable for my tank, but I have a few feather dusters, a diamond watchman goby, some zooanthids, and whatever else may be growing on my live rock. I've cycled the tank for awhile now, and just got the goby a few days ago to help keep my sand churned and clean. I've read that a refugium will help keep the sand stocked with plenty of foods for him. What should they be? And do I add them to the refugium?? I've read about copepods and amphipods..but am so confused. Are they necessary?? Please help! Thank you!
