Elos:
Both tests came out at 9.0dKH
pH at the time was 8.24 (Pinpoint).
Hmmmm, I don't know what to believe now. I like the Salifert reading better  .
One other thing to note about the Elos kit....some of their KH kits currently "out there" have an incorrect 5ml line on the vial. It is lower than it should be. So, when measuring the water amount measure to the syringe 5ml line, not the vial line. I have one of the screwed up vials.

Yeah I don't which to believe either now
With mine though I find it hard to believe the salifert test because for one it was inconsistent but also after many days without kalk and very little alk dosing, the alk had to of dropped. If I go with the Elos, it has dropped to 7. Which is perfect
But I don't want to only go by the Elos kit just because its giving me the number I like. Running ZEO with a high alk (over 10) could kill my tank!
On another note, I found the K+ test from Korallen Zucht to be very easy to use and seems like a very well put together kit. Although I have nothing to compare it to since I have never tested potassium before now.
