Steve, I take no responsibility for your staining.
wsun: thanks! I used aquamend to hold up certain pieces that weren't as stable. Just hold the aquamend there for a little bit and the rock as well and after a few it solidifies. Once its fully cured, its as hard as a rock. I haven't had to scrape coralline yet, however, its slowly starting to grow. The tank has only been running for about 1.5 months now.
