I am not new to the hobby, but I've been out of the game for awhile. I want to set up a nano tank using my old rock. Its not live anymore and been sitting in a bucket dry for a few months. What I would like to know is if I can cycle my new tank with this rock or should I give it an acid bath first? I will not be running a skimmer on this tank so any "cycle quick" kits are not an option for me.
