Hi,
I'm out here on Guam and have two 12 gallon Nano's. I've upgraded the light to 48 watts. Recently there was a power outage and I lost both so I'm starting up again. I returned my old live rock to the sea and found some new rock that really looks great. Some thousands of years ago, when Guam was an active volcano, lava poured into the ocean, wrapping around the coral that was on the fringe of the island. A lot has broken off and can be found on some beaches. The rock is dark and quite dense although it doesn't seem to have become basalt. The question is whether this stuff could ever be good live rock. Much of the rock seems to be dense enough that it would never absorb sea water.
Many of the discussions of live rock seem to be based on the assumption that anaerobic bacteria live inside of the rock and help the aquarium deal with the build up of nitrate. The question is whether that is correct, and if it is, then would this kind of volcanic rock ever be able to serve as real live rock?
