I've read the first and 3rd page of your thread. The vision you have for your tank is very much like my tank system. Mine is a little bigger with a 56g display, a 30g XH refugium and a 20g sump. My display has 13 fish; 2 cardinal fish, 1 firefish, 1 royal gramma, 1 barnacle blenny, 1 tomini tang, 1 ocellaris clownfish, 1 carpenter wrasse, and 5 yellow tail damsels. There are 2 salt acclimated mollies in the fuge with lots of grass shrimp and a few peppermints as well to provide shrimp larvae for the display as food. There are macros and seagrass in the fuge. The 20g sump has rock to be home to copepods, and amphipods.
I feed very heavy to nourish the coral, macros and seagrass. Usually I feed a cube of frozen and 2 generous feedings of flakes and pellets.
Anyway I will be following your progress.
