AP Master Test Kit

#1
Just got my first one and I gotta question.

The instructions indicate the first drop of the KH test will turn blue. Does this mean the drops in the KH bottle should be blue? Because mine are orange.

The instructions indicate the first drop of the GH test will turn orange. Does this mean the drops in the GH bottle should be orange? Because mine are blue.

I am wondering if my instructions are wrong or if my bottles are mis-labeled.

No, it means that the water in your test tube will turn color after the first drop of test solution is added.

The stuff in the bottles should never change color while still in the bottle. If they do you're looking at contamination.
