Help with salifert test kits

Not sure if each test kit has diffrent syring tips?
well every time i fill to the 1ml mark each test kit is diffrent reading?

calcuim= .80
mag=.81
alk/kh= .78

is this right or did i mix up my test kits tips?

You problably didn't mix them up...I personally don't think the hobby test kits are accurate enough to where 0.01mL really makes a difference anyhow.

Ensuring there is no liquid in the syringe, the tip is on nice and tight, and the black plunger is seated properly may help you draw in the same volume on all three.

You should not fill the water to the 1 ml mark, you move the leading edge of the plunger to the 1 mL mark. When doing that, you will always dispense 1 mL, even if the tip holds 50 mL and you never see any water in the barrel.

yeah I do that and those #'s are what I read when I get to the 1ml mark? the rest is air

Those number are not important, since they just measure the air volume of the tip, in the end. There's no need to worry.
