I think it'll look better once it's covered with corals. One underlying principle is that no rock rests on any other rock. Thus, i can pull any rock out without affecting the structure. With all the trouble i've had with fireworms, bubble algae, nasty crabs I like this concept. Also, the structure is hollow. I have one closed loop in each blowing straight up from the CL boxes to keep crap from settling on the rock and i can also blow out the inner structure with a MJ and hose. No sand gets past the PVC bottom pipes so easy to keep clean. More function than beauty i suppose.
