Just a curious question, If I have enough base rock already and decide not to buy any live rock, is there anyway to grow the purple coraline on the base rock without using live rock? Just wondering.
To actually answer your question. Yes, you can seed base rock without lr. Just to clarify, just because it's lr doesn't mean it has coralline on it.
Anyways, find someone with a bunch of coralline; possibly your lfs and scrape some off the glass of the tank (they don't want it on the glass anyways). Take a razor or credit card and put some airline behind. Scrape and siphon the coralline into a container and add it to your tank.
