Hydrogen Peroxide 35%-- which you must "dilute" with pure distilled water to achieve the desired concentration as follows:
1 part 35% Hydrogen Peroxide to 6 parts distilled water yields the recommended 6% solution.
For example: 1/4 cup of 35% Hydrogen Peroxide plus 1 1/2 cups of distilled water = 1 3/4 cups of 6% Hydrogen Peroxide.
A 1-to-2 ratio of 35% Hydrogen Peroxide to distilled water would yield an 18% Hydrogen Peroxide solution.
A 1-to-3 ratio of 35% Hydrogen Peroxide to distilled water would yield a 12% Hydrogen Peroxide solution.
Thus you can adjust the % Hydrogen Peroxide as desired to accommodate the rate at which oxygen is dispensed into the aquarium.
As of 8/22/09, you can purchase 1 quart of food grade 35% Hydrogen Peroxide for $21.83 plus $9.33 shipping. They also sell pints and gallons, but don't forget -- you're diluting that 35% Hydrogen Peroxide by a factor of 6-to-1, so 1 quart of 35% Hydrogen Peroxide yields 1 3/4 gallons of 6% Hydrogen Peroxide.
