Thanks for the rock, it's sitting in a vat of saltwater in my keg bucket.
I thought i finished my plumbing this morning, but I found a leak in a bulkhead. I have to fix that and then I can add the rock and the sand that I bought from Steve an Reef Plus.
48 gallon tank, 70lbs rock, and 60lbs sand (20 live 40 non-live)
I'll start a thread with pictures when it's finished.
