0 nitrite, 0 ammonia, and less than ten nitrate is cycled IMO... unless you JUST added the water and gravel and didn't do anything else. then i would say you should add some pure ammonia and see how much it takes out in 24 hours. now, if you did do that step along with adding the established water and gravel... IMO, stocking slowly at first to give the bacteria colony some time to adjust and you should be ok.
