Hey, I recently bought a new salifert calcium test kit as my old one was empty and I've been having a few issues with it.
The new instructions are add 2ml water, add a scoop of powder(don't mix) fill the syringe to the 1.00ml mark and put in to the lower end of the piston is at 0.4ml, swirl and the colour should go from blue to pink.
Only problem is it doesn't go pink. It just stays blue. If I keep adding it goes pink at the 0.2ml mark then blue again at 0.08ml mark.
So right now I am reading that as calcium being 460. Or am I way off since it didn't change colour when it was supposed to?
