I'll agree that larger differences between GH and alkalinity are fairly
rare in natural water (particularly in surface water). But fairly rare
conditions don't necessarily create problems. Incidentally, I think
something in your quote above got lost in the interpretation. Is there an
alternative wording for "Ionen spectrum physiological"?

What are the consequences, or symptoms of the imbalance? I've
continuously maintained tanks on my tap water (hardness 1 degree,
alkalinity, 7-8 degrees) for as much as 13 years and I don't have any
problems that I would attribute to GH being much less than alkalinity.
Perhaps if I knew what the symptoms were then it would turn out that
problems I attributed to other causes were actually related to that
