Nitrogen Cycling 2 Weeks w/ No Changes


I am brand new to fish keeping, and I have a question. I am currently cycling my 15 gallon tropical fish tank with 3 blue long fin danios (and a ghost shrimp). I introduced the fish into the tank exactly 2 weeks ago. 2 days before I added the fish, I set up the aquarium with the filter, heater, gravel, plants, and a bottle of Tetra SafeStart. I have tested the water conditions every other day since I introduced the fish, and none of the numbers have changed since the first day. They are currently stuck at pH 8.0, ammonia at 0.25, nitrite at 0, and nitrates around 0-2.5 range. Does this mean my tank is cycled? Does it take this long for the ammonia to start rising?

As much as the cycling process is sped up by using filter media and or substrate as bio-seed from an established tank, 'instant cycle' from a bottle is possible. It seems logical that very soon, cycling new tanks using ammonia or prongs will be a thing of the past as we'll just pour x ounces per gallon of water of instant cycle and immediately add fish.
The only catch is different people experience different results with the current products on the market. Perhaps some have exceeded their viable shelf life, were not added to properly conditioned water, were not added in the proper amount... will need to monitor to ensure against a dangerous ammonia spike which can occur even when bacteria supplements are used.

How many plants you have in there? With 3 fish and some shrimp you should see more ammonia then that. Also how often have you been doing water changes during the cycle? One last thing, what test kit are you using?
