Carl Talked a bit about pegging in his Tank Tour
Video. I've included what was in his video, and added some more things he said
about it. The key to it is really drilling holes in your rock while you do your
aquascaping. That way you have places to put your corals when your tank is full.
It's a great Idea, and I'll be copying it myself soon. So I may add more to this
as I do it. Since we didnt focus too much on it at Carls.
