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.
