I'm curious about people putting what sounds like pool covers over their
ponds to keep the heat in and prevent evaporative cooling. Here in New
England my pond (4-5 foot deep) gets a 1-2 foot layer of solid ice over most
of the surface (except where I actively prevent it). So, won't any sort of
pond cover just get frozen into the ice eventually?

The big advantage however is keeping my filter system up & running, as
I'm
100% convinced that one should not stop filtering a koi pond. The
bacteria
will survive, they will go dormant or perform at a very very low level,
but
they will still be there when spring kicks in.

In agreement there. I was just reading a short print out regarding this,
that the bacteria don't die, they just go dormant. I assume freezing solid
might do them in, but with slow circulation they should hang in there. Not
sure how I'm going to implement this with my system, but I do plan to keep
some of the bio-foam in operation this season some how.

I just wished I'd read it earlier as I could have cleaned some of the
bio-foam earlier when it was warmer. ~ jan
