I'm in the process of setting up a 12G nano cube with 15-20lbs of live rock and a 2 inch live sand bed. My amonia, nitrite and nitrate have all been 0 for over a week now even after a 50% water change. 4 days ago I noticed one of my live rocks turning white. Today it is totally white but amonia nitrate, nitrite are still 0. Is this cause for concern? I was going to get my clean up crew tomorrow, but not sure now. I plan on only having 1 small clownfish or 1 firefisjh in this tank. Any help would be appreciated. :help:
