My instructions say put 1ml of water in the vial, but that amount barely covers the bottom of the vial.The vial has 10 ml and 20 ml marks. So im thinking the directions are supposed to say fill the vial with 10ml of water not 1ml. Anyone know what the correct amount is?

I'm sure the instructions are correct. It is only about 1/4" of water.
You can hold it side ways to the color card to get a 10x dilution measurement.
