Okay, what am I doing wrong. The water was blue, not pink when I added the microspoon of chemical, no drops added.

It means your water is soft already. If it was pink, then however many drops you add to turn it blue, thats how many grains hard your water is. Since you did not have to add any drops that means your water is 0 grains hard.

What is the hardness range for this test kit? Thanks

You can always dilute your sample to extend the range. Dilute with soft water (distilled, clean rain water, or previously softened water). Just check that the soft water tests for zero hardness before using it. 1:1 dilution would double your range. 1:9 would extend the range by a factor of 10. A cheap drugstore syringe could be used for dilutions if you don't want to eyeball it.

Does this kit come with the test tube and mixing bottle like the one from Hach?

Hach's part number 145300 does come with the measuring tube PN43800 and Glass Bottle PN 43900

Why would the color of soft water turn blue as soon as the indicator is added to the sample, without any additionof the titrant?

This happens normally, if the water is soft (zero grains of harness). The grains of hardness is the number of drops of titrant you have to add to get the water to turn blue. If you do not have to add any drops of titrant, then you have zero grains!
