Help cycling with established tank water

I have a 2 gallon tank (no fish or plants) that I got an hour ago. I heard that it is possible to cycle a tank in a day with water from an old tank. I filled the tank halfway with water from a 35 gallon that is cycled. The rest was regular treated water. They use different media so I can't use the big tank's media. I have bacteria that you buy to cycle tanks that I added. Is this all I need to do? Am I done?

The Opry ain't over till the fat bacteria sings!

First, the beneficial bacteria is attached to [filter] media, substrate and decor, not the water column.
You might have some advantage with the bacteria in a bottle product (some are great, others not so much), but even with that, there is a process to establish nitrosomonas and nitrobacter bacteria colonies with sufficient numbers to take care of ammonia and nitrite bidness.
