Actually, i just bought a brand new salifert ammonia test kit. It also read zero ammonia. So far, i have used 2 different Salifert test kits, 1 new and 1 existing, as well as an API test kit. Also used 2 dr tims Ammonium chloride, 1 existing and 1 new. Still reading zero on all my test kits...

It is possible for the bacteria population that you dosed in your tank to be ample enough to take care of the ammonia you dosed three days ago., but the tank still not be able to handle the bio load of fish. It is also possible you added enough bacteria that it is ready to go right now. It is possible to add enough bacteria to instant cycle the nitrogen portion of cycling a tank.
If you believe the tank to be cycled, the best thing to do now is to toss in the same amount of food you plan to daily, and then test in 8 and 24 hours. If ammonia is 0 you are ready to go.
Some people like to add a copepod starter at this point and continue to feed the tank and let the pods do their thing until you start to hit the algae cycles. Then toss in your clean up crew, then after a week or so toss in your fish.
I prefer this method myself as it is much easier to go through the algae cycle with a fishless/coral less tank.
I really think one of the keys to a successful tank is all of the micro fauna, so I add mine in deliberately just like I add my bacteria deliberately.
If you go the pod route Tisbe and Apocalypse pods are my two favorite ones to add.
