Has anyone experienced strange readings for pH from the API freshwater test kit? I got mine in the mail today and was so excited that I decided to test it out. When I measured everything other than the pH, the results were great and matched the color chart, but when it came to pH, it went to the 7.6 color box. This means that the pH is so high that it doesn't fit within that kit's range. I freaked out (super high for my tank) and decided to use the high range pH to see just how high it was. And I got the 7.4 result? This means that the pH is lower than 7.4, which is too low for that kit to measure. I'm so confused. Is my pH higher than 7.6 or lower than 7.4? I did the test twice for each and got the same results.
