So with the API Master Kit, I got my results and I can't really even tell the difference between the light yellow color corresponding to 0 ppm and the slighlty green tinted yellow color corresponding to .25 ppm.
Does anyone else have this problem? If so, what do you do? I guess you just act as if it were .25 ppm to be safe?
That is kind of annoying though, I researched for a while for the best kit and it apparently was the API Master Kit. I am not impressed at all right now with the kit though since these colors are so close together.
