I'm looking for someone who has used pure oxygen before. I'd like to create a raceway to raise a few tiger bass. I think that delivering a little bit of pure oxygen would be benificial in maintaining the health of my fish. What would be an appropriate sized tank? What would be the amount of O2 delivered to have a positive impact on fish health? How can I calculate my annual costs? I realize this question is an aquaculture type problem, but every aquaculture site that I visit seems to think I need to spend $5,000 or more to get started. I know I can do better. I'd like to attempt to feed train some of the tigers, sell the ones that don't feed train and keep the rest for my pond. I'm sure a few of you might find the results of my project interesting.

Thanks
