I just got my liverock today from the LFS
, 15 pounds, for my 29 gallon tank. I have two questions.
One is, can I scrub the liverock off? It looks like it has "dirt" on it. Will this hurt the rock? Also, I have this plant on it that looks like Thanksgiving Cactus (long flat green leaves), that is sorta unsightly, but kinda cool. Should I take it off, can I take it off, and how do I? Just pull it?
Second, I read that you can't lay down sand and then add liverock on top, as it could create pockets of posionous gas. Is this true? If it is...how do I add more liverock in the future? Or do I have to wait until ALL of my liverock is in place and then add the sand. I want to put the sand in tonight, around the 3 pieces that I already have.
Thanks for your help!
