Yes, I originally intended on only 4 racks but I didn't realize how much some of them liked being on the bottom rack, shaded and low flow. The plate coral puffs up really big and his tentacles are really long. It's really doing good, the 2 plates in my RSM are struggling. Probably because of the high water flow...
I'll probably end up with about 6 racks total. I never intended on keeping fish in my tank and the two spot keeps burying everything I put on the ground, so I can't have any kind of frags in the sand. I'll move him when I set up the RSM 250 and it will be a frag only tank again. I know I can't put him and the royal gamma in the RSM 130, the clowns are really bullies!
