Tetratest Laborett Lost Color Chart

[nukeonekitty]

I have the Tetratest Laborett water test set... I lost the color chart for the KH/GH... does anyone know if you can go online somewhere to locate a new color chart?

The GH and KH tests don't use a colour chart. For these, you add drops of reagent one at a time and your reading equals the number of drops required to change the colour of the sample. For KH, it's the number of drops required to change the sample from blue to yellow. For GH it's red to green.
