One thing i suggest though for your tank is some new lights. In your first pic your corals are really nice, but look drained. I would hook up some new LEDS to give your corals that amazing blacklight glow.
looking good am i know youve spent a ton on all that always wanted to turn my 4 x 2 x 2.5 high into a reef but i start looking at prices and reliese i cant afford it lol
