Just a quick question on live rock seeding. I'm starting a new tank with 50 lbs of dry rock. I'm buying a few pounds of live rock to seed it. There are a few options for me to buy and they are in different colors. One stores is brownish, on is more natural looking with some green, and one is mostly purple. Will the color of the stuff on the rocks go to the rest of the dry rocks? If so the purple rock looks really awesome, but is almost double the price, but it would be worth it if the rest of my rocks took on that coloration.
