OK, I just cannot read this thing. I can't discern any difference on the card from 10-20 or from 40-80 (although I have never been that high). As a very Type-A person I find this quite aggravating. Particularly since I am training myself to maintain the tank for a blue ram and keep it under 20ppm, so it's pretty relevant for me to know if it's at 10 or 20...
I've tried reading it in vary lights and in different ways but I still can't decide what I am seeing.
Are there other test brands with more easily readable differences??
It made me think I have bad color vision to discern oranges and reds so I took an online color perception test and I got a perfect score, so I blame the API test
(If the test sounds fun it is here)
