The change of color for some test kit is very substle. I would recommend to use Sera brand kH and GH, the color change is the most obvious.

Another possibility is the test kits is spoilt which will noy color change.

starbucks: For API tests, you add a drop of the solution... shake. If the GH hasn't turned green yet, add another and repeat. For KH you wait till it turns yellow.

If it turns green or yellow right away you have very soft water.

In the species list, you will find general information about each type.

The test is basically count how many drops it takes to cause a color change, and then correlate that to your GH/KH levels.

Perhaps yes, it maybe as straigh forward as putting them together or a long period like weeks of acclaimisation is needed, this depend on what the pH are the 2 species of shrimps were bred in and kept in.

I would say around ph=6.7 will be best for both.

What kind of test kit are you using? Your test kit should come with a chart that correlates the kH/GH with colors.
