Question about Salifert KH/Alk Test kit

This just came in, and I'm happy with it so far, seems easy enough. My question is (for anyone else that may use this test kit) For the color change, it says "Continue adding drops until the color changes from blue/green to an orange-red or pink color (whichever color is observed first). When i did the test the solution turned a shade of purple at around 11 dKH and didn't turn into the clear pink color until 12.2 dKH, so which color change should I be looking for, a clearly pink solution or the purple color.

Thanks in advance

If I did the test right, my dKH is @ 12.2 btw.

Other reading are:

Ca = 465 ppm
Mg = 1520 ppm

 

I just add the drops until it turns completely from pink to the blue , close is as good as it gets with any kit. I'd say you are at about 11 or 12 DKH

 

Okay cool thank you!!

 

Pink is the final color to look for. Luna

 

pink to blue is the colors for the API Alk test. But Tangster is right, that you don't need to be any more exact in your Alk readings than saying your Alk is about 11 or 12.
My API kit does 1 drop per dKH reading. I can't read 12.2 dKH, b/c I can't put in 0.2 drops from the bottle. It's more just don't care to than can't - I could if I wanted to using a small syringe like the one that comes in the Mag test kit...but it's not necessary.

 

Keep adding drops until its a nice pinky orange, mine turned out to be 8dkh...
