Aquarium Water Testing? So, I’m considering getting an aquarium of my own, and taking care of it on my own. 

I was curious if there were any colorblind people with a fish tank that test the pH, nitrite, nitrate, carbonate &amp; general hardness with the *water testing strips just using their phone to detect the color of the strips?*

Or if there are any options that are a little bit more colorblind friendly than color coded testing strips?
