Using "seasoned tank water" is of minimal value.
It might provide some seed stock of bacteria but the vast majority of the beneficial bacteria live on and in the substrate, rock and surfaces of the tank.
The water itself is pretty much neutral when it comes to removing ammonia from the system.
IF the rock was in a tank that was operating just fine, was not dried or left out of water for an extended period of time, it will do a fairly good job of removing the ammonia to a point. This rock in the tank with new water is a better place for fish than a bucket. DO HAVE water changes ready as if the ammonia starts to overwhelm the rock you will need to step in with water changes.
