test result on salifert mag
 

Can someone confirm when using this kit on average how much Mg-3 solution one should use?{ example 1/2 or 3/4 of mg-3} or what the reading should be to get about 1350 ppm?
(or how much solution should be left in the syringe).I just want to confirm my readings.

You should have .1 ml left in the syringe for 1350
