Ok not to beat a dead horse but...
I have to use this test because I can't buy anything for awhile.
In these pictures it's easier for me to tell when the color begins to change from blue to orange. What shade of orange am I looking for here? The VERY first sign of orange? Or am I looking for the final picture where it's a dark orange? Dkh
range in these pictures is 9.5-14. I suppose I can manage with that as long as I maintain it within this range but that seems huge. I don't know much about it but I feel like this could lead me to some potential problems.
