We have bought rock together and it grows great in my tank but not his. I put a rock from his tank in my display and refugium and both will be purple within a couple of weeks. And those are 5-10lb rocks.

What I would do then, is take the rock back to his tank, scrape off all the coralline and let the spores spread through the tank. That will often help seed the rest of the surfaces.
