It's a 55 gallon breeder tank where I built-in the sump and refugium as a peninsula to the left. Build photos are in my profile. Don't have the room for the peninsula, but planning to sell it eventually anyway. I know the rock work is a little busy, but the colors are finally starting to blend in well. Honest opinions on how this can be improved, even if it's to remove something. Maybe some low light corals in the shaded areas? What animal can I put in the refugium as a display that won't eat the copepods? Are there different macroalgea than cheato?
