Add the tank water, add 1 spoon of the powder, and add 1 drop from the syringe and swirl. Much easier than having to cap the test tube and shake every time. Result of the water test. 395ppm.
Not that bad IMO.

If you have an approx idea of where your calcium's sitting at, you can add about 75% of the Salifert reagent in the syringe, all at once. Swirl 5 or so seconds to allow proper mixing and then continue adding drop by drop and swirling after each drop until the colour changes.
Much faster this way
