Like I've said before. The second looks a little too dark. But it seems to me as if it's working for the corals, you should keep with it. We only have to look at it, which, it still looks great, but the corals have to live in it, and would you sacrifice their happiness, which could lead to their eventual demise, or would you sacrifice a little of you own. I would keep it how it is in the 2nd picture. Sorry to change my mind.
