I agree with the Wizard. My limited experience with oxygenating well water has taught me that air bubbles alone will not bring DO levels up enough for trout. I transfer fish in a 100 gallon stock tank, filled up the night before and aerated with two 18" aquarium airstones. When I get to the fish farm I have them check DO levels. The DO levels after 18 hrs of bubble aeration, are not high enough to support long term trout survival (although sufficient for short term travel).
I haven't experimented with using O2 or O3, but I like the idea of Cecil's packed column because it would be less costly than purchasing gas or O2/O3 generators. I like the mechanics of Cecil's packed Column, because we switch the ratio of water/air, so it is droplets of water passing through air. This frees up trapped gasses and exposes more of the water's surface area to air.
