    Mine took 3 months to get all the levels right, but i think thats very rare. use some commercial bacteria to kick start the process

    If you do a fishless cycle or cycle with fish, it normally takes between a month to 6 weeks. A cycled tank has zero ammonia, zero nitrites, and a nitrate reading.
