That's the funny thing, the bottle says to stop dosing when either ammonia or nitrites are in the 5-10 ppm range and then just leave it. When both ammonia and nitrites hit zero, you're done.
I was a bit dubious at first since every other fishless cycling guide tells you to keep dosing ammonia until it falls to zero within 12 hours, so I might continue dosing to 1-2ppm and testing just to be sure.
