For some odd reason, this image will NOT upload to my Clownfish Harem Tank thread. No worries. As long as I can get the help that is what matters. So I was to add Cheato to this with a light of some sort. I also want to keep the protein skimmer. Any suggestions? I have the RedSea Reefer 350. I saw online that some people have converted the ATO to the refugium. I'm game for that, but I'll need a step by step guide to doing so.
