API GH/KH Test Kit

[WillC]

So I wanted to run this by the collective...

If I am reading the instructions correctly for my API kit, GH is supposed to go from Orange to Green and KH is supposed to go from Blue to Yellow.

The testing solution in my kit seems off. GH is green/blue and the KH is orange. You can see the color of the liquid in the tip of the solution bottle.

Any thoughts?

Just tested my tap water.  My solution colors are as yours.

KH

1 drop, shake = blue.

2 drops, shake = yellow.

 

GH

1 drop, shake = orange

3 drops, shake - green

 

Seems right to me.

What colors are the drops? Picture added to show what I am talking about.

Same as yours = 'My solution colors are as yours.'

Add a drop of KH solution to your tap water and shake it.
