Silly question.

When I started my 70gal tank, I wasn't completely informed on live rock. I bought live sand, got the salinity right, and threw in some dry rocks. The tank has since been going with fish in it for 8 months with 0 problems. Is all that dry rock considered live now? It has a green coating on most parts. Is there a way to check?

Thanks

 

The live sand you used help to cultivate the rock.

 

That makes sense. I'm still new when it comes to the whole concept, so any information is helpful

 

The key point about live rock, is not the higher life forms (good , bad and indifferent types) that you get with it
but that Live rock, has an established colony of bacteria, that process the wastes through the various aspects of the nitrogen cycle

dead rock becomes live rock over a period of time, as bacteria will be generated naturally due to the waste from fish and other live creatures
a significant percentage of that bacteria will colonise the rock ( and other surfaces in the aquarium)

thus at 8 months, you do in fact have live rock in there
