Hi, I am planning on beginning a 55 gallon reef tank very shortly. I plan on mainly cultivating corals such as LPS, SPS, Zoanthids, and other softies. I have always wanted a school of chromis in my tank and my "plan" is to set up the 55 gallon with an overflow to a sump that has mechanical filtration with filter floss, carbon, phosphate remover, and a good size skimmer. That will be followed with a reverse light cycle refugium, lastly the pump will return water to my tank. With this filtration setup can I house 5 blue reef chromis, 2 pink skunk clownfish (paired), a yasha haze goby, and a sand sifting goby? I am hoping with regular water changes and a good skimmer I will be able to overcome the nitrates produced by these fish, plus the sand sifting goby is meant for reef cleaning purposes not because he looks pretty.
