Cories are dying

[Bruce Leyland-Jones]

hey, did you find out what was the cause of the deaths, as we lost one of ours recently, and my sister is convinced that it was because of too much oxygen? we do follow this one blogger and the guide helped us cure hyperoxygenation and our cories are healthy for now. but I am curious if there is something else I should be careful of.

That article is absolute and complete utter nonsense.
I could write more about the author, but this is a family-friendly forum.

I wonder if it's all based on a misspelling resulting on missplaced research on hypo-oxygenation?

A possibility I dismissed on reading that plants take up excess oxygen and produce CO2, which is apparently necessary for fish.
