Thanks for your help.
What started as a diversion, has now become a joy :-)
I'm already thinking about next year's extension, and possibly a new pond !

The foam is probably protein on the surface of the water which foams when
it
is hit by waterfall or air stones. It is harmless, though somewhat
distracting. To remove the protein, overflow the pond washing the surface
with a garden hose to the overflow point, and a lot of it will be washed
over. If it is a lot of foam and it showed up all at once, that is a sign
of spawning and you need to keep an eye on the ammonia and nitrites and
not
feed until they are back under control.
