I need help.

When I use the Seachem Calcium test I never am sure that I got the corrrect water amount in the pipette. My method - as for the other Seachem test kits with smaller pipettes - is to squeeze the bulb of the pipette and put the bottom of the pipette into the aquarium water, then release the bulb pressure gradually while watching the water come up to the 1 ml (?) mark. When I see it's at the proper level, I try to pull the pipette out of the water while maintaining the same bulb pressure, but unlike the smaller pipettes provided with other Seachem kits, the larger pipette's water level lowers as soon as I lift it from the water. I can't seem to get the water level to lock at the proper mark.

What am I doing wrong, or what should I try?

Thanks very much!
