Help on Sera gh test Kit

[Kenng]

Hi Bros,

Hope someone can help me read the gh with the Sera gh test kit.
The color changed from brown to green after 10 drops of the solution.
It is stated as 5 drops = 5dGH in the instruction. So this will be read as gh 10 or?

Thank you

yes is reading is 10

That is strange, I test on water in a tank that I just reset.
I will try on tap water and see the result again.

Thank you all for the help.
Somehow it did not work the 1st time.
Now after testing a few times on different water like tapwater, my planted tank and shrimp tank, now can see the color change easily.
Glad that it is working.
