Live rock or dry

[Aquattro]

I'm with Kien on this. Liverock, IMO, is the single most important aspect of a successful reef. Sure, you can get around it with dry, but it's going to be easier, and I think a nicer tank with all live. It contains biodiversity you're just not going to get from dry, or even a 70/30 mix of dry/live. Yes, it's expensive, but to me, it's worth it.
