Mine took 5 wks. Can take anywhere from 4-8 wks. But every tank is different, so don’t go by time but by your water parameters and how your tank seems to you. This is a good time to invest in your test kits if you haven’t already done so.
I know this is the hardest part(all the waiting) but believe me, if you give your tank the time it needs, it will in the long run be more enjoyable. The people that don’t wait are the ones with all the problems and some just give up because of it. Don’t get me wrong, you’ll have some problems but nothing you wont be able to handle.
