What's the best ph test kit?

[MattinIdaho]

I've only used the API and it is horrible. I have no idea what color is showing. I can't even begin to guess between two colors. I really like Salifert for Ak and Mg but have heard it is similar to the API as far as matching colors. Without going to a prob (which I will do eventually) what is the best test kit available?

ph probe calibrated properly...test kits aren't going to get it right but you can always try salifert but IMO ph kits are worthless

Elos changes colors in 1 drop no more guessing. And best is a controller with the probe.... IMO
