I just measured the hardness of a batch of aged tap water with a Hagen test kit. It comes in as
GH 100ppm (IE it took 5 drops of reagent for color change)
KH 80ppm (IE it took 8 drops of reagent for color change)
the "ppm" units is how the test kit defines its results. It also says ppm is the same as mg/L as CaCO3 (calcium carbonat).
I see most people post their GH/KH in numbers like 5 and 6 etc. with no units. Is there a conversion from ppm to these other units?
How soft whould you say this water is? The test kit suggests the above values are "slightly hard" (the kit's words).
What is your opinion of these values as to discus grow out and breeding suitability?
