I’d setting up a 150 SPS dominant reef. should I use a 40 beeder or 55 gallon? My goal is to have a chamber with a an ATO reservoir. House a bio brick or whatever the current bio media is, my reef octopus. Ive had no success with refugiums before. Is this due to lack of nutrients typically? I already have a 40 breeder but though of using it for a frag tank.
