Sorry guys, but this doesn't seem a likely chain of events. First, from
what I've read, CO2 in the water does *not* displace oxygen in the water.
Second, unless the glass cover was air-tight, the CO2 would not have been
trapped under it. Third, if it was air-tight, *all* gases would have been
trapped, including oxygen.
I don't doubt what happened to Dave's fish happened, but I suspect a
