Questions about zoos

[kuatto]

Was thinking about setting up a frag grow out tank(55gal) for zoos and other assorted corals when I finally set up the 115.Was on the Garf site and like their rack system.One of their statements about zoo growth was they noticed better growth on tanks with no skimmers,anyone have any exsperience with this?What method worked best for you,keeping in mind this tank will be house only frags on a rack system,no fish or live rock.
I'll be using a large canister filter for filtration
