Haha I will have to charge a small fee though. This one took me about 10 minutes to get the rock stable on top like that.

did my first scape tower/structure tonght. second rock blob to follow tomorrow. Will post pics when finished. I spent about 40 minutes on mine tonight, but I was using a drill w/ masonry bit, acrylic rods and reef safe epoxy...
