I am looking for an accurate ph test kit where it is easy to distinguish colours.
I have a problem in that I am partially colour blind, and colours that are sometimes the least bit simliar are indistinguishable to me....
I have an API master liquid test kit, which measures differences 0.2, but when it gets down to ph 6.4, 6.6, and 6.8 I struggle to tell the diff
Help would be most appreciated.
