New Tank Help

HI, All Setup a new tank 210L 46gallon a week ago using a fluval ext 3 filter containing bio-max and carbon.

i have put 9 danios in the tank all levels are at 0 ammonia, nitrate .PH 7.2 feeding twice a day. My question is there enough fish in to cycle the tank.

Please help

Still pretty green with tanks myself, but I used 10 danios to cycle my 26G, so I would think you should have at least 15 in yours, maybe even 20. Otherwise your cycle may take a LONG time or not happen at all since the Danios won't put enough ammonia into the water to allow the bacteria to start grow.

Yes you can cycle the tank with 9 danios but
the cycle period may be greater than 28 days and
the danios may not be happy fish if the ammonia and nitrites rise very, very slowly before they peak (your post indicated nitrates but I believe you meant nitrites).

I cycled my 110G tank with 12 guppies, seven cories and 6 gold nuggets.
I fed very little and barely observed an ammonia and subsequent nitrite concentration.

The ammonia concentration was not detectable at 14 days and the nitrite concentration was not detectable at 21 days.
