I am color blind and use mostly Hanna checkers to test my reef tank but they do not have a nitrate checker and was wondering what everybody's opinion was on the best most user friendly test kit for nitrates was that would be the easiest to see.

agreed on the phosphate one. 3 different shades of white for the first three is a nightmare.I have a similar problem with you, not very good with colors. I have found that the Red Sea one is the best for my eyes (and most accurate). Colors are pretty distinct even in the low ranges and the wheel helps. Their phosphate though unreadable![]()

Red Sea Pro is really good.
NYOS is very good too and very easy.
I really do not like the Salifert kit, especially the way they handle high and low range.
