Are there any reliable pH pens out there that are used to test fresh/salt water. I am going to adopt the tradition of doing a freshwater dip with methylene blue on all incoming fish as part of the QT regiment. I don't really want to use pH test kits where you have to read a color chart just to be sure that the pH of the FW is equal to the SW the fish is coming from. Anyone use any of the pH pens that you see on auction sites that are actually reliable? I see a lot of them say +/- .1 pH accuracy.. is that too much of a fluctuation? It sounds like a small amount but if you think the pH scale is a logarithmic scale of base ten.. Thanks!
Or if you don't use a pH pen what do you use for accurate readings of pH for a freshwater dip?
