I am asking for recommendations for accurate freshwater testing that also has good color differentiation. I am currently using API's GH, KH, Ammonia, Nitrite and Nitrate kits but the color differentiation is hard for these half-century old eyes to see. The GH and KH tests aren't bad since they change colors entirely, not shades of a color, but the other three, for me, are hit & miss. I use a handheld digital meter for pH and also have a pH controller tied into the CO2 injection system.
Thank You,
