I’m using the API freshwater master test kit. The low pH test says it is 7.6 or above, and the high pH test seems to say it’s 7.4? Could I be colorblind? What do you guys think? Added a photo here. 280985AA-E6A6-4C11-9B1F-9BEEE10CB78D.jpg Thanks for the help in advance!
Looks like 7.4 to me ...
Thank you!
