Keep in mind that all cylinders will undergo a change in their buoyancy characteristics during a dive as the gas that is contained inside of them is breathed. This means that you will always start the dive more negative, or sinking if you have no air in your BCD, then as the dive progresses you will become more positively buoyant as the tank becomes lighter because of the gas being breathed from it. The cylinder will be lighter at the end of the dive because it has less gas in it, and you will be more positively buoyant. If you performed the buoyancy check correctly, you will still not float. In this video I demonstrate how a full tank sinks while an empty one floats.
