Key points thus far...
Possible implementation:
Ghost feedings, coral foods, amino acids, and your basic chemistry. I think keeping algae at bay would be the hardest part. Snails only do so good IME and fish are a big help.
Algae maybe controlled by Verbrint.
Benefits without fish are, water will be super clear, easy to control NO3 and PO4. Easier to feed coral without fish grabbing coral food. No detritus.
Quarantined every piece of coral prior to introducing it to your display tank. Dip's in H2O2, Flatworm exit, etc. to help eliminate unwanted pests and other things.
Algea scrubber or refugium should help considerably.
