I use both Red Sea and Salifert and Red Sea measures higher. Red Sea gets 1280, Salifert gets 1215. Low I know. I'm working on adjusting it. That's a big difference between the two kits but they're both low anyway.

Big whorls have little whorls, Which feed on their velocity;
And little whorls have lesser whorls, And so on to viscosity
