Is this live stock already in the tank?
Every time I have moved a tank I have invested is Rubbermaid Totes. I put the rock and corals in them with water from the tank and transport that way. I put a power head in them to keep the water moving if it is going to be more than couple hours. I'd also add a heater if they are going to be someplace where it will be hard to keep the temp around 75 - 80.
I'd get new sand. I learned the hard way old sand is nothing but trouble. It doesn't have to be live, it will become live fast enough.
