Someone explain me some math..

[Aquattro]

So I've just opened my first Elos Ca test kit, and reading the instructions, the math goes like this

50 x number of drops C
+
10 x number of drops D

eg - 8 drops of C = 450mg/l + 5 drops of D + 50mg/l =total Ca of 425mg/l


not when I was in school it weren't....

Elos directions make my brain hurt.

I had an elios kit.. I solved the math problem easily,, I gave it to Jake!

1 drop of c = 50. so when you get to say 400 and the colour has not changed switch to D. +10
so 8 drops of c = 400 then add on drop of d and if it changes then your ca is 410. if it takes 2 drops of d to change colour then its 420, and so on.

All I know is 1+1=2

I usually add 7 drops of C (350) and then switch to D so as to not over-shoot the mark. If all goes well I add 7 drops C (350) + 7 drops D (70) = 420

Well ya, I got that figured out in all of about a second, but should I be using a test kit where they can't even get the directions right? This isn't a translation problem, pretty sure math is math, even in German. What other QC are they sloppy on?

just use API much easier and accurate enough. and when it's not and you get Pi$$ed it is cheaper when you pitch it out the window

Or give it to Jake

Jake's got enough lately

The kit is easy enough to use, although my test showed Ca at 450, which is higher than I would have expected. Salifert generally gives me about 420.
