12 gallon 2 days old

If no2 is 0 and No3 is elevated, you may be ready for your first small fish like a damsel...but im doubtful....if they are all zero, you never cycled :-/

 

No2: 0
No3: 0

 

then you probably didnt cycle :-/

 

Do you have any fish in tank, or did you put any thing to start cycle?

 

i made a mistake with the NO3 its not 0 i retested it but im waiting the 5 minutes for the color to stabilize in the bottle

and i have sand and live rock in the tank

 

OOOhh good, that would STINK if it came out to 0

 

NO3 is 20

 

then, that means, you should be cycled, and perhaps ready to add a damselfish.............

 

so all tests results

PH: 8.0
Ammonia: 0
NO2: 0
NO3: 20

What should i do next?

 

Do a water change, and get a small hardy fish like a clown fish or damselfish
