200 Gallon Build - Used Rock help

[Scubado63]

I am getting ready to start setting up a 200 gallon bow front I got from someone that tore it down, I have been working on for a while now, accumulating equipment, building new stand, ect.... I have a few hundred pounds of rock, it was sitting in the back of a trailer outside for a while, what is the best thing to do to get it ready to use in the tank (pic below) .... any help appreciated, after turkey day sales< I can now start working to get it going..... I will start a build thread now that I can actually start putting it together .....

Soak in 50/50 vinegar solution overnight then rinse well before placing in tank. Let it cure for a long time to ensure a thriving system in the future!
