    Yes, there are quite a few man made and even natural bodies of water that are artificially oxygenated. Bubble diffusers seem to be the most common method. Also interesting: after the oil embargo, energy became expensive so wastewater treatment plants switched from surface to bubble aeration which is several times more efficient. Yet in the aquarium surface agitation is king...

    There's always something. When I was doing some informal water pump vs. wavemaker vs. air stone tests, I noticed dissolved oxygen was actually going down with the water pump (on the bottom of the tank moving water upwards). The extra current seemed to be making my fish expend more energy.

    This is one of the earlier studies that attempted to quantify surface vs. bubble transfer in a bubble plume. I do have a regulator intended for inert gases. I only need a metering valve, a flow meter, and a rented nitrogen tank and I can perform a similar experiment.

Experiments were conducted to separate these two sources of dissolved...

    One thing that's already been done is to alternate between nitrogen and air and measure the difference in dissolved oxygen levels.
  5. Coronal Mass Ejection Carl
    Is the tank reasonably heavily stocked? You'll probably need to have a fair amount of oxygen demand to be able to see the difference.

    It's not just the distance but the increased water pressure at depth. I never officially tested it but when I did water changes and there was only a few inches of water the air stone didn't seem to work very well.

    They more or less do the same thing so I would use one at a time.

    A member of my local club operates a drinking water plant so I asked him about chlorine spikes killing fish. He said plants don't send out more than 3.5 mg/L chlorine. Prime neutralizes 3.22 mg/L chloramine so I would have to do a near 100% water change and still might not have a lethal amount of residual chloramine.

    Are you using a liquid carbon or "liquid CO2" product such as Excel?
  10. Coronal Mass Ejection Carl
    Strange, since the reagents don't contain chloride. And Prime probably doesn't contain sodium thiosulfate.

    Red gills plus flashing that starts after a water change could be due to chlorine/chloramine. You'd be surprised how ineffective RO/DI is at removing chlorine/chloramine. The low levels that can harm fish are difficult to detect with test strips made to detect swimming pool levels of chlorine.
