Hi All! My tank has been cycling for 3 weeks. I have checked the levels 3 times and today the ammonia and nitrite were at 0ppm and the nitrates were at 5ppm. Is it safe to add
fish? There is some debate online as to whether nitrates should also be 0pp or if a low level is okay.

A level as low as 5ppm is ok to add fish. Does ammonia go to 0 after 24 hours and your nitrites stay 0? If so your all good

Last time I checked, ammonia was 0.25 and nitrites were 2ppm and nitrates were 5ppm. So the numbers are definitely coming down
