The test kit doesn't expire until 10/19. I suppose it could be operator error but it's a pretty simple test. I can't imagine I could screw it up that much. It has never measured in a normal range so it very well could be a bad test kit. I recently moved my sump and added 60 gallons of new water so it's not like I haven't done a water change recently.
