BTW, do you all scrub the rock while curing? The pamphlet I got with the rock said to. I am not really sure what should be scrubbed off though. There are not to many white patches but there appear to be some stuff that might have been alive at some point. Some black stuff is there too.
I ended up taking a toothbrush and lightly brusing the ok. I had swished the rock in a bucket before placing it in the tank originally. There were a few dead worms coming out of holes and some stuff I have no idea what it was.
