If that is indeed the problem, the fastest way to put more
oxygen in the water is a bit of hydrogen peroxide.

Dieter Untergasser mentions this specifically in "Handbook
of fish Diseases" (TFH Press) P 132

He suggess 25 ml of 3% peroxide per 100 liters if aquarium water
and cites Krause 1985. In no case can this dose be repeated.
