My real reason for asking was for its filtration properties, not just for looks. Yeah, it would be great to have rock that looked like live rock with coraline algae growth and all of that stuff. But I know with a fish only tank like I have, I do not have the correct lighting for that kind of growth. But, that's not what I'm really interested in. What I really want it for is its ability to reduce nitrates. Will my base rock ever obtain that capability??
