Should go with Real Reef rocks as top layer and those base rocks as base rocks...lol. Remember, you're going stare at those boring looking rocks for a long time...in your amazing new setup...Update: Rocks came in today. 50lb normal marco rock, 20lb prime cuts marco rock. Have it circulating in a brute curing with Dr. Tim's ammonia. Will probably add some Dr. Tim's One and Only to it tomorrow, once correct ammonia levels are achieved. This plus sand the ~50lb of live rock from our combined two aquariums should be enough for the time being.
