Uses electrical current to split H2O into hydrogen gas and oxygen gas.
The process is called hydrolysis. Yes it does produce oxygen,
no it does not remove carbon dioxide from the live well.
Works well in pure fresh water, I see problems with efficiency in salt water
as salt water is a better conductor of electrical current.
Another problem may be from the generation of chlorine gas caused by splitting NaCl (salt)
which I'm pretty sure is how chlorine generators work in swimming pools.

Looks like there are additional additives needed in saltwater
to prevent chlorine from concentrating to levels high enough to kill your bait...

Thanks Brett for the info. I would give it another try using the U2 product adding some stress coat to give the water the rest of additives needed if not back to cabelas for a refund. But defenetly a grat product.
