What kind of rock can I use to cultivate it?

Question

I have about 40 lbs of high quality live rock. I want to find some other kind of rock that I can put in with it to see if I can't get stuff to grow on it. I am not sure what kind of rock I can use. I want it to be able to go in my saltwater aquarium. If you could just give me some advice on what type of rock to use or a place that sells it for real cheap.

Answer 1

Many aquarium stores sell dry base rock that is intended to be used for this
