how do ya'll feel about the electronic testers, like the tds meter, or a ph meter?
My biggest issue with the test kits is that it requires me to distinguish very subtle color differences, and while my vision is 20/20, i still have a really hard time telling weather or not the test tube is closer to this shade of green or that one.
i've tried count the drop test kits, and i've tried the dip a strip kind, and i still have a helluva hard time reading them...
Suggestions? is there something out there that will make this easier for me, cause as it is now, i just dont test anything unless someone with better color recoginition than i have is at the house...
