Principle. When Hydrogen Peroxide comes into contact with silver oxide it produces pure Oxygen and a by product of pure soft water. The Hydrogen peroxide is prevented from direct contact with the shipping bag water because of the pressure of oxygen being vented through the oxygen outlet tube. As the reaction goes forward the hydrogen peroxide is converted to water and remains in the test tube, while the generated oxygen is vented to the bag containing the fish.

The oxygen release tube is very small. like a large pin hole use the smallest tubing possible. I use a tube about half the diameter of a knitting needle. When the unit is dropped into the bag, the unit will float bottom down if weighted properly on the bottom. The oxygen is then released slowly into the bag.

When building the unit make sure that the bottom of the release tube is well above the liquid level in the test tube.
