how long does it tank for a new 25 gallon tank to cycle?
i let my tank cycle 4 2weeks just 2 b safe but it can take only afew days in sum tanks
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.
