Ordinarily I would agree with you hawk but his nitrite numbers are zero and his nitrate values are climbing. If the tank had not completed its ammonia cycle, it would not have completed its nitrite cycle and there would be a non-zero value for nitrite.

Now, it's possible that the nitrite test kit is giving a false negative, but IMHO this is less likely than an ammonia test kit giving a false positive. If the ammonia reading is non-zero but low (ie. close to zero) and unchanging over a long period of time, I would distrust that reading. If it is changing then it is likely valid, but unchanging is suspect, espescially if nitrite is zero.

FWIW some people will start up a new tank with existing rock and existing water and start stocking it the next day. Basically If you have the appropriate mass of rock a cycle can be very quick. With over 100lbs of rock (so over 1lb/gal), with 2/3 being cycled rock already .... I think it's a pretty safe bet that his initial cycle is done.

Tell you what, here's a real acid test, throw a frag of something like GSP or zoos or something in the tank and see how they do. If there's ammonia they won't open up, if they do open up though then it's probably safe to start moving other things in there.
