Eh .. noticed that u do not hav a skimmer, 1 of the neccessary equipments of marine fish keeping.
Mayb u can consider connecting ur main tank to a sump where u can house a skimmer and mayb other equipments in future. It can also b a place to hide ur LR if u intend to keep ur main tank empty (not sure if it's really advisable .. )
Juz some suggestions.
All de best for ur set up
