I Can't See The Color Change In My Calcium Test Kit!

[srgtkoons]

I have the same problem. So i use Fastest for calcium and alk. The alk is a bit difficult for me to read. But the Ca test changes from purple to blue. Not sure if that will be of any use for you. Depends on what type of colorblindness you have.

I am somewhat color blind, (like "somewhat pregnant?") I use a Salifert calcium test kit, but I can't tell when the water goes from pinkish to light blue at the end point of the test, thus I don't know what my calcium level is. What other calcium test kits can you recommend with a prominent end-point change for us color vision-challenged people?
