I agree with Jim. What he is dealing with is worthy of keeping the focus solely on cycling the tank and learning the ropes of it.
Nitrites of 2-4 ppm are deadly without detox. Make sure you are detoxifying them right.
Do the fish still feed? That'd be a good sign that you are doing it right.
You don't really need the nitrate (nitrAte) test. When your ammonia and nitrite are firmly at zero ppm for a while, like a week, without any changes in your tank (fish are fed and still feed), then you can say your tank's cycled. But as I wrote before, cycling is a live process, it constantly adjusts to everything that happens in a fish tank.
As an extra assurance and learning, testing for nitrAtes could help you indeed as the guys suggest above.
Also, you asked before how you'd know when the cycling is done and you were explained it, in this thread, I think at least 2-3 times. Please read and reread this thread if you remember that a question had already been posed and answered... otherwise you risk making it seem like you value your time and don't value ours. Just my 2 cents. We will still try to help you, one of us or another, but we as people have a nasty habit of overanalyzing the actions of others and underanalyzing our own and forgiving and excusing ourselves for what we don't forgive or excuse the others.
