dock, the tank looks great ,I have a few tanks and evvery so often I rearrange things and it seems like I have a whole new different part of the ocean in the house..I think the tank does look to be a little dark,and your salt level w/corals need to be closer to natural sea water..I was wondering how the lr looked as far as color or coraline algea on it..maybe thats what you think you might be missing( once again I cant tell in the pic)..I would just rearrange stuff first and see how you like it then,but its still very nice how it is..HTH
