I imagine that some holes would need to be drilled through this ice cap
for O2/CO2 exchange. The surface is 320 sq.ft. Anyone have suggestions
on hole diameter, quantity and distribution?

Ingrid, that's quite clever. I'm going to take a look at the draft
angle of their pond's sides.
thanks!

I chose to cover the pond with a "tent" so even with power failure the
water doesnt
really freeze. other than that, those further north into 3 country
wait until the
water freezes 2-3 inches then draws the water down another couple
inches leaving the
ice "cap" with an air buffer no more water freezes. the hole stays
open.

There should be special awards of merit for perseverance (or masochism
;~) for ponders in Canada. Power failure + sub-zero weather, and you
can
hear the ponders outside overnight, chipping the ice, drinking hot
chocolate, cursing up a storm.

a 12" square hole (reciprocating saw) outta do it. I personally prefer 1" spade bit
on a cordless when my ponds froze over. Ingrid

Nice tiny stream of HOT water to "cut" through the ice with little or
now sound to excite the fish. Just a thought. :-) .
