Ok. Before I glue the rest of this down…. Need opinions. This is my first big tank so I don’t have tried understanding of flow yet and I’m not always an imagine visual kinda gal. So how is flow looking? I have 2 Nero 5a. This is a 120. 22? 23? Ish inches of height to overflow. Tallest point on left is 15” which I could lose an inch or so of that. I’d just lose that little arch. Tallest on R is all the way to the right where the shelf is that will actually sit down on the edge a bit more and stick out further as pictured in #2. Or I have a thinner piece that may actually look more balanced as compared to L side shelf (pictures in (3&4) Enough books and crannies? Swim room? Too much rock? Are front island too much too heavy appearing? Any other suggestions? Looking at mixed reef. Possibly SPS one day but going to take it slow and see how well I manage. haha. I’ll try to add video in comments it was too large
