YAY, my LFS finally got in a bare-bones 5 gallon for me today, so tomorrow I'll be setting it up and it will get to sit completely empty except for the water until Friday, when my light hood is supposed to be coming in. My plan was to add live sand and rock at that time, but I was wondering... is it ok to add them both at the same time, or should I add the sand first a let it sit a while before going for the rock? I'm trying to take this very slowly and ease into it, so once I have the rock it'll just be sitting there for several weeks if not several months before I try anything else... I was just wondering if I've got a better chance of getting this thing set up without a horrific crash of some sort if I let the sand settle first before getting rock?
