Just a slight possibility of German ownership there I would surmise :-)

A traditional (Italian)(!) remedy for manky wells was to shove in a few
shovelfuls of lime (exactly what type of lime I don't know, sorry).
Apparently this kills all bugs going. The downside is that it also makes
the
beautifully soft well-water hard as nails.

I think you probably are faced with emptying the tank (tie up ballcock or
turn off at mains, and run off cold water), baling out the sediment, and
then scrubbing with Milton. If the tank doesn't have a proper lid then you
can get "water bylaw" kits from the plumbers merchants with lids and
stuff.

Or go main water system with combi or heat bank. Storage tanks are spurned
upon because of what you experienced. The Americans think we are mad using
them.
