Water testing question


Recommended Posts

So I bought the Salifert Calcium, Alk, and Mag kits.  I am having trouble (or I’m dumb one of the two) with the syringes.  When I pull the reagent up the amount inside is way different than what the picture shows in the instructions.  Is this normal?

Looks normal. The example is simply pointing at the area where the black plunger needs to be positioned. The air gap is the displacement of air from the plunger to the opening prior to filling. As long as the plunger is pulled from 0 to 1 you will have 1 ml no matter the air gap.
