esshup, From what you said I was way over loaded, 1lb of fish per gallon of water over twice what you said with pure O2. I have a O2 tank I could rig up. Do you use a regulator like one on a cutting rig? What do you set the psi to? Does it require a nozzle or just an open hose? Will to much O2 cause a problem?
As far as the CNBG 2000 small 1 to 1 1/2" and 200 3 to 4" in each tank with 40 gallons of water. On that trip I hauled 40lbs of fatheads back in bags. The trip is about 1 1/2 hours and didn't loose a single one.
