what about the airpocket I have created with the cover, is the gas

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

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.

With all the rain we have been having, all the snow and ice has melted
off the cover of the pond, so I desided to pull back the cover and get
some air in there, the temp. will be above 0C for a bit.
