We did a combination of dry rock and live rock from KP Aquatics. It has been 13 months since we started the tank and we have the back wall and most of the rock covered in coralline, a couple of different colors. We have some really cool sponges in different colors, some tunicates that seem to come and go, a bunch of limpets I'm trying to control. The live rock also brought in some scallops, brittle starfish, a couple of pistol shrimp, bristle worms. We have a few spots of bubble algae, also.
We didn't add anything that I can think of. We had to dose small amounts of phosphates at first. We also have 6 medium size fish, some soft corals and 2 LPS that are doing well, an Acan and some variety of Euphyllia.
