Tim,
I also have some extra sand from the 4 bags I bought.
I have one 50lb bag I haven't opened and probably another 50 lbs I just scooped out of my tank last night and is in a bucket. I might have more if I can't get my water to clear up. My filters and diatom have been running like crazy since Sunday and the water is still way cloudy.

If I could work out a time when I am in town and getting my wife's SUV we could swap for some live rock.
