For those of you, like myself, who spent $325 for duel livewell oxygen systems... what is your personal opinion and experience after using these livewell oxygen generators in the hot months July and August to keep a limit of bass healthy all day?

Just wondering, thanks.

I'm not sold. I believe keeping the livewells iced cool is the most effective means of keeping the bass alive. In the summer months, cool your livewells and turn livewells to recirculate, then every couple hours dump the old water and refresh with new water and re-ice. The fish will come out hot and charged.

Don't get me wrong the Oxygenator does help, but I don't see the neccessary need if you're using ice. If you livewells are setup to only bring in fresh water, then the Oxygenator is probably worth the money.

Thanks for your opinions fellows.

osborntofish; after reading the technical fine print about how oxygenators really work, cooling aerated livewell water with ice is as always the standard recommendation, but cooling livewell water in conjunction with an oxygenator is self defeating because the cooler the water is the less O2 the oxygenator delivers. Water temperature regulates and controls the amount of O2 oxygen generators put out which brings us full circle right back to the original problem which is low oxygen levels in livewell water and how to fix it.

The salesman told me eye-ball to eye-ball that in order to maximize the amount of O2 oxygenators put out, the warmer the livewell water the more O2 they put out which is the whole point, don't chill the water. The oxygen production is inverse to the water temperature. Hotter water = more O2 produced by the oxygenator; cooler water = less O2 production. I save alot of money because I eliminate all the extra cost and hassle eliminating all this stuff.

I do change out my livewell water with warm surface water several times an hour and I use no ice, no salt, no chemicals.

Your statement about Oxygenators efficiency vs water temp was a new on on me, so I did a little research. I did indeed find that there is a "high temperature" electrolysis process which is more efficient. There doesn't appear to be a significant change until the water changes phase into steam....so it's well below any temps, we as bass anglers, would ever encounter....unless we're cooking the fish?

An oxygen solubility chart will clearly show that cold water holds significantly more DO than warm. Here's a nice chart to check out: http://users.vcnet.com/rrenshaw/do.html The warmer the water, the less DO it will hold, regardless of the source of the O2. Interestingly, fish also react to the warmer water temperature by increasing their metabolism which, in turn, causes them to use more oxygen.

So, in closing, cooling your wells in conjunction with an oxygenator will only serve to reduce the time needed saturate livewell water with DO (you can only put so much O2 in a given amount of water at a given temperature).

Regards,
BT
