To which test?

KH add 5ml water to test tube
Add 1 drop at a time to test tube shaking after each drop until water turns blue.
Multiply the number of drops by 10 to determine the KH.
Divide the KH by 17.8 to determine the dKH.

GH add 5ml water to test tube
Add 1 drop at a time to test tube shaking after each drop until water turns blue.
Multiply the number of drops by 20 to determine the GH.
Divide the GH by 17.8 to determine the dGH.
