Looks awesome. Love how you made the caves. How are you supporting all of it? Is it just stacked? Looks like if one rock slipped, then everything would crash. If I would re-aquascape my tank, I would do something like you have. I envy your rockworking skills. . .lol
Thank you all for the great comments. All my rock was stacked in the from the start, I layed eggcrate down and then the sand and peace by peace I created what I have If you notice the main support is from the center rock and out to the over flows.
