This was about 18 broken pieces of rock that I super glued into one larger one. Piece by piece of course. Notice the decorative loop on the right side. I got the rock from Oahu. After my first few weeks and a water change to remove nitrate I got a couple of really small purple live rocks from a really nice store and razor bladed them in the water to release coralline algae that spread like crazy so I have a lot of purple in my tank now. 10 weeks in. Third tank.
