as it hits as low as -40C here in the Toronto Area, I finally desided to
check on the pond for the first time this winter, I had built a teepee
style top over my small pond which at the centre is about 18inch high down
to about 8 inches around the sides, I have an air hose doing the bubbles
and I have covering over the whole top heavy liner, since it snowed, I have
about 6 inches of snow over the whole pond.

Today I dug out a portion of the liner where the airline is to see how much
of a hole has been kept open, and to my surprise, there is no ice on the
pond at all.

Last year I did the same thing but there wasnt any snow and I had ice about
6 inches thick.

Snow really works well as an insulator.

I recovered the liner with snow, my question is this

its pretty much an airtight lid over the pond, the bubbles are keeping the
surface of the water moving so the gases dont settles over the water, but
what about the airpocket I have created with the cover, is the gas
collecting in there, should I have some venting happening ? could I just
over the liner once in a while to put fresh air in there ?

Joel.

yes, you need a vent all the time. Ingrid

-40C? You must be in North Toronto! I think the worst I've seen was -23C
or so.

Today I dug out a portion of the liner where the airline is to see how
much
of a hole has been kept open, and to my surprise, there is no ice on the
pond at all.

I checked mine about a week ago and it was the same as yours, no ice.

Last year I did the same thing but there wasnt any snow and I had ice
about
6 inches thick.

I had the same concern, especially with the layer of freezing rain we had
last week. Although there's about a foot of air space between the water and
the cover. I'll have to get my ice pick out and dig them out.

If you know that the air pump is pumping air to the bubbler inside
the cover then there is fresh air comnig in through the bubbler. If
the cover doesn't look like it will explode, then the air is venting
out somewhere. (You don't have anything near an airtight seal.)

I'm in Thornhill, it's mild now, above 0C.

I'll have to see how I can put a vent in without the animals going in to
where its warmer without letting too much cold in.

True its not "air tight" but it looks like a good seal and fresh air is
entering from the airline

Mine is actually under the cover, which seemed like a good idea at the time.
It keeps the air pump warm, so there is less chance of the diaphram
freezing/cracking. But the boundry between warm air under the cover and
cooler air above the cover is causing serious condensation on the pump. So
far it has not killed it, but it was soaking wet this morning.

I guess I had not considered the possibility of the pump under the cover.

One of the other suggestions often made to keep bad gasses from
developing under the ices is to allow ice to form, then lower the water
level. If this is ok, then I would think a cover isn't any worse.

You might put teh pump under some flower pot (upside down)
to keep moisture from dripping on it.

Where is your air pump? If outside the enclosure it would be sucking fresh
air in, if not, probably need some way for fresh air exchange. Especially
if it is as tight as you think. ~ jan

My pump is outside the covered pond in another covered area away from any
wind chill, the pomp seems to be holding out.

Forgive my cynical nature, but I doubt any of us porgs have managed to build
a pond cover that is air tight.

Mine certainly isn't, but the snow and 1/4" of freezing rain helped. It
formed a very hard crust over the whole shebang. Although there's about a
foot between the water and the cover, so I don't think it's much of an
issue.
