Ok guys i need your help here I have a 90 gallon tank and a 20 gallon wet/dry sump. I am going to get rid of it. Because it is too tall for underneath my setup and i cant put a protein skimmer in it or do any maintenance. I want to get a 20 gallon or 30 gallon tank and turn it into a refugium. Now question is do you think thats big enough for a 90 gallon tank. I want to put my protein skimmer in it because i hate the HOB kind. Also how do i turn it into a refugium. I know you need macro algea live sand and live rock. Anything else....?
