17 Sep 2015 I have the same issue. I am using dry rock and dry sand, but live bacteria. Ammonia seems dropping very fast, but nitrite level still stays 2 ppm and

Longer answer: ammonia and nitrite should never be allowed to go above 0ppm. Anything above that is toxic to fish. Nitrate should never be allowed to go over 40ppm though we like to keep it below 20ppm so that there is some space for it to rise due to--late water change, mild overfeeding, little bit of real plants turning brown (all of which could result in higher nitrate)
