The last picture is a huge piece. But we build it out of like 20-30 small pieces. Took long time to drill, cement, and make some adjustments with a power tool. At the end looks like 1 really big pieceNice.. the tonga pieces I got were all small. so I did the best I could with what I had. My goal was to get more coral space and I think i accomplished that. I used existing rock scape and added tonga branch on top. rock scape before what too high and limited space to put corals. I will post pics of my finished scape later or tomorrow.
