Product:KH is measured in dKH (degrees of KH) or ppm (parts per million), where 1 dKH equals 17.9 ppm. It is the measure of the amount of carbonates and bicarbonates in your aquarium.
Some substrates, rocks, and corals can alter your aquarium KH level. As such, consideration must be given before adding such materials. KH affects the buffering capacity of your water. KH helps neutralize acids and prevents pH fluctuations. Sudden large pH fluctuations can cause health issues and even death for your life stock. 
Typically, freshwater aquariums should be between 4-8 dKH (or 70-140 ppm). Some substrates, rocks, and corals can alter your aquarium KH level.
 
Instructions:

Add 5ml of aquarium water in to the test vial.
Add the KH reagent by the drops. Swirl gently after each drop and observe for color change from blue to yellow. Keep a count of the number of drops till color change.
Match the number of drops counted against the value in the chart.

Each drop of KH reagent corresponds to 1dKH unit. Most fresh water aquaria require a KH value of 6 – 8 dKH.
