I'm slowly increasing my phosphate dosing but I want to at least see more or less what the level is now.

Is the API phosphate test accurate enough to measure in the 2-3 ppm range?

Also, does the kit actually expire and become inaccurate or is the expiration date just on there for kicks?

It's good enough. I would suggest you find hoppys instructions on calibration. That will help you be more accurate.
