I've also heard that reducing the hardness hinders fungal growth. But
maybe this theory was thought up because the eggs fungus because of what
you said. i.e. fungus is a symptom rather than a cause.

>Apparently  filtering through carbon will reduce the carbonate hardness.

I've never heard this before though!
