Nice looking tank, however, you should remove the bubbler. Air stones are harmful in a saltwater tank.
The negatives of an air stone/bubbler are:
-air can get lodged in a fishes gills
-air stones do not give you gallon per hour turns - like powerheads do
-can cause bubble algae (air bubbles all over your live rock - not the bubble algae emerald crabs eat)
-can cause stress to the fish (popeye)
-cause salt creep which in turn causes irregular salinity/SG
-when bubbles pop the water can get on your lights causing the life off your lights to decline rapidly,
Some periodic air bubbles are not harmful, but constant ones are.
