I'm no expert on this but I think GH/KH level are determined by what will be in your tank. My KH is one drop. I haven't supplemented it since my ph is high...and I haven't experienced problems. My GH is also one drop but since I have plants and snails I use GH boost to increase it.

What's in the tank?

I need to test straight from tap first to know where I stand.

Kribs , bolivian rams and tetra will be living in it

Sorry reread your post...your test result are determined by how many drops it takes to change the color. KH results are when the blue changes to orange. Once you have your results then you can adjust KH levels to what is required for your tanks inhabitants.

Try reading the direct sheet. It explains everything.

Test from the tank. If you haven't filled your tank yet...test from the tap.

That's all I was asking in the original post. What color water am I looking for in the tube when test in complete. Yes I did mention the water went blue but I didn't know what color I had to wait for to show up after continued drops.

Put the drops of reagent in the tube one at a time.
At each drop count.
One drop = 1 German degree of hardness. (or less)
Two drops = 2 German degrees of hardness.
and so on.
Shake after each drop.
When the color is no longer blue it is turning to orange or pale orange-yellow.
Sometimes the color is very distinctly BLUE at a certain drop, then ORANGE at the next. That is the answer. The count that turned it orange.
There might be a sort of 'in-between... not blue any more, but not orange' shade. I go one more drop after that, then call the answer half way in between, for example:
4 drops might be that 'not quite there' shade
5 drops is really there.
Result: I call it 4.5 degrees.
---------------------------------------------
To fine tune this you can take twice as much water. (larger test tube) and count like this:
One drop = .5 dKH
Two drops = 1.0 dKH
Three drops = 1.5 dKH
and so on.
