Thanks Matthew. It's only shallow ,about 30cm, with a 60cm diameter hole
about 60cm deep in the centre where I have planted the water lilies. There
is no filtration or water flow and yes a certain amount of small leaves do
blow into the pond but not what I would call excessive. It is only a
plastic lined pond so as you can see I didn't spend a lot on it :-)
I do not feed the fish at all.
Thanks also Adrian for that comprehensive info.

Cheers, Darrell
