Ha! The left side has had massive coral growth over the years....in this photo it had just been pruned back for the zillionth time. The problem with this system is it was pieced together in the days before reef ready aquaria. Its a simply AGA corner bow sitting on a very light particle board stand. Over the years I modified by adding an overflow and a small acrylic sump that is barely adequate but is the only thing that will fit in the narrow area underneath. Proper skimming has been an issue due to lack of space. Water damage over the years has led to the stand rotting and will collapse sometime soon. Despite its overall success- its time to take it down and move things over where they can truly strive.It's a shame your changing the tank now. I particularly like the right side as it is now, but the left side would turn out stunning too after a few months of coral growth.
I agree though that the scape is appealing given the short-comings of this shape aquaria. I tried to create a canyon effect that does not photograph well. The space between the two structures is long, deep and irregular and is very pleasant to look at. When the corals are at their largest the left structure towers and gets large toward the back of the tank.
Anyways, thanks for looking and the comments!
Cheers
