I'm no expert, and from the sound of it, neither is the LFS owner.

In other words, I think that guy is wrong but I'm sure someone else can
verify that like boomer.

Well this might sound like a dump question from the subject but am kind of
confused.

I went to the LFS to get a calcium test kit and this time i am buying the
SeaTest test kit and after a brief conversation with the owner. he told
me
to test it correctly and i asked him what do u mean by correctly. He said
when you add the reagent drop by drop to count how many drops, i should
stop
when the drop hit the solution in the test tube ( not after you shake or
swirl until the reagent has mixed in well with the rest of the test
water ).

As far as i know, if the reagent is to react with all Calcium ion in the
test solution, i should be swirling and shake it to make sure all Calcium
ions are reacted to get an accurate reading rather than on at the top
portion when the drop hits the water and turns blue.

Can someone shed some lights on this.

Thx in advance for any help.
