Live Rock and Base Rock ?

[njbluefish]

I bought 3 Lbs. of LR and set it between some base rock that had no life at all. Now a just a few weeks later I noticed some purple on the Base rock. I moved the rock around and there is more purple on other rocks now. Can the live rock make other rock live that quick? I want to add some more live rock...........what kind of live rock should I buy? Your suggestions would be much appreciated.

Purchase enough Live Sand (I'm preaching again) to create a 4" deep sand bed and then add your live rock on top to your liking without concern for help as a biofilter. Create an ecosystem that's nice to look at and great for your animals - let the live sand do the work.
