thanks to all for their advice. I agree, if I'm moving a lot of fish a long ways I need a bubbler or oxygen system.

But I'm intrigued by the study I posted above where the tablets did 'something' that outperformed everything else and kept the fish alive in a small space with no water change for quite a while (overnight)

I'd like some help from the forum to figure out what the 'something' is and then can build from that science towards a new application.

But it isn't your fault if you don't know what is in those magic tabs. I guess I need to call the company smile They will probably say that the formula is stored in a vault right next the original Coca Cola recipe.
