I would think Hydrogen Peroxide would be harmfull to the fishes gills if not in the correct dose maybe even in the correct dose? Think what Hydrogen Peroxide does to our cut on our skin. Would you want to swallow this? Or put it up your nose? Gills are very sensitive and I think people are walking a thin line with the useage of this. You would have to make sure your dose is right by all means. Like you all said "Do the math". I believe i will stick to my OTABS! They work great in a live well and for transporting live bait.
