I'm getting live rock this weekend for my tank that has been going for a year now. I added live rock before but nothing seemed to happen to my base rock. I'm trying to figure out what to do when I add new live rock now. Tank is 90g and I have about 60 pounds of base rock and 20 pounds of live rock which I added about 11 months ago and it never spread. My base rock turned a nasty brownish color. And the 20 pound of live rock doesn't look much better.
What should I do to get the new live rock I'm buying this weekend to spread?
