The center rock was just added. It was a trial piece from Real Reef Rock that I convinced them to sell me at Macna. Again -- still not sure what to put on it.Beautiful, like the rockscape and wrasse collection. Looks like you added a “rock fill” since the original Jester6 version? Did you add the reef brites at the same time as T5s or did you get them later? Do you feel like the reef brites help acro coloring, make colors show better, or both?
