These pics were taken on March 12, 2016. The tank with it's live rock structure was just set up a few days earlier. There's about 22lbs of live rock all connected together by acrylic rod, zip ties and Quikrete hydraulic cement to create a one piece structure. I wanted to have the rock have very little contact with the substrate and it does not touch the back of the tank. This should allow for good water flow and not too much detritus build up. I'm looking forward to stocking this thing.
