Also, the cycle ends up taking longer because there is no nitrifying bacteria to break down food and fish/invert detritus, so the ammonia builds up and doesn't go away properly.
If your tank was fully cycled, and now you're seeing ammonia and nitrites, get your livestock out into a fully cycled tank and let this tank go through the mini-cycle that is in progress. Or, you can try one of those products that handles ammonia, but personally I don't like putting any chemical into my tank that I can't test for.
well the girl at the fish store said that if i got the base rock,live rock,and this stuff that puts bacteria in the tank then i could put fish in the fourth day(which of course i didnt)
