Finally finally, you could probably get by until then by just refilling
the
barrel with clean water, that will give the lily something better than
rotting gunge to overwinter in.

Surely the most straightforward way of coping is to simply replace a
quarter
or so of the water daily until the problem disappears?

Dont forget there are no fish. I doubt the lily would care whether the water
was 25% changed or all in one go,and you'd also be sure to get all the
rotting gunge at the bottom which a water change wouldnt necessarily touch
and which appears to be the root of the problem.
