What do the directions say to do? I never added ammonia to a tank in any form, but I'm guessing what's happening is your have low ammonia because you have enough nitrifying bacteria to deal with most of what you add, and you can see that in the high nitrite levels, which in turn leads to high nitrate levels. I mean the fact that your nitrates are so high means it is in fact breaking stuff down, which for a relatively "dead" tank doesn't occur.
Do be prepared to do a fairly big water change when your cycle has completely though.
