I'm using the Red Sea drops to test my nitrates but I have a problem in that I have some colorblindness and can't see the difference between 5, 10, and 20. Is there another test kit that I could use or am I stuck until I can buy a digital($$$$) tester?
I know the ideal is to get it to zero but I'm having no luck as of yet
