There is no expiry date on the bottles, I threw the cardboard away when I first got it. The problem I see is the first colour change is at 5.0ppm so anything under that just reads 0. Do you know if you can double the drops to test inbetween 0 and 5? Or is unrealistic to get these values in a reef tank.
