I haven't been to Exotic in a long time, might check them out one of these weekends. I thought about doing the online thing, like Premium Aquatics or the aquacultured stuff from Tampa Bay Saltwater. The thing is, I am not sure how much rock I will end up using since I want to keep it fairly open with some larger sandy areas. I will probably start out with maybe 200-300 pounds and go from there, maybe from John's store.
The nearest store to me is Aqualife, they sell LR as well, but I haven't looked at it that closely yet.
