Looks good! Two minor points of consideration I have (if you haven't already thought of them, of course):Got the cabinet together and out the rocks in. Let me know what you think of the aquas along. Was trying to do the whole negative space thing but with some nooks and hiding spotsView attachment 48664View attachment 48665
1. Depending on how tall the tank is, the coral(s) on the top of those arches are going to get a LOT of light compared to the ones a bit further down/might be a bit shaded due to the verticality of some of the rock.
2. Flow in between the rocks may be a little challenging (although it seems, with the openings in the 'middle' of two of the pieces of rock, that would be mitigated)
Great design, and looking forward to seeing the build progress!
