When to clean filter?

K30 wrote regarding dreams of the pond.

Oh my yes, nightmares, pond draining, fish swimming in the waterless pond,
in the air, or all flopping on the bottom. That my neighbors own raccoons
and let them loose at night.

Koi ponds got covered for fall today, suppose to have wind tomorrow, if we
do, at least there will be one less chore for me to do, that of skimming
out the leaves or vaccing them off the bottom. First time I've covered them
before a big wind hit. ~ jan
