How to Use DuPont™ Oxone®


Oxone® can be added to pool water day or night, and swimming can resume after a short waiting period to allow for adequate mixing and dispersion throughout the pool. No mixing is required. Products formulated with Oxone® are completely soluble in water and dissolve immediately; they should be used weekly for routine oxidation and also for special situations throughout the season.

When there are no swimmers in the water, simply broadcast Oxone® slowly and uniformly over the surface of the water, adding about two-thirds of the total dose over the deep end. Add with the filter running to ensure complete mixing and good circulation.

Oxone® dissolves quickly, so after 15 minutes of circulation the oxidizer will spread throughout the water and you can safely enter the pool. Read and follow the label directions on the product that contains Oxone®.
Weekly Oxidation with Oxone® Stops Problems Before They Start

DuPont recommends regularly weekly oxidation with products containing Oxone® to prevent problems, like cloudy water and burning eyes, before they start. Regular weekly oxidation with Oxone® removes contaminants before they build up to the point where corrective action is required. With products containing Oxone®, the pool water is always clean and clear, and ready for swimming.

Don't wait until the water becomes dull or cloudy, or until swimmers begin to complain of burning eyes, before shock oxidizing the water. It is usually more costly, time consuming, and labor intensive to correct problems than it is to prevent them from happening in the first place. Corrective treatments often start with adding a heavy dose of oxidizer, then waiting overnight for the oxidized debris to settle to the bottom of the pool. Next the pool must be vacuumed, and in many cases the filter may even have to be cleaned. During this process the pool is out of service.

If you are currently using a chlorine shock product for weekly oxidation or corrective shock treatment, temporarily boosting the chlorine level introduces its own set of problems. When heavy doses of chlorine are added to water with organic material present, organic chloramines are formed. These chloramines, also referred to as combined chlorine, are the very compounds that irritate swimmers' skin and eyes, and cause that strong chlorine-like odor often associated with the smell of indoor pools. Shock doses of chlorine also raise the chlorine level above 4 parts per million (ppm) and swimming cannot resume until the free chlorine level drops back down to safe levels (between 1-4 ppm); this is called the "re-entry level."

Fortunately, you can avoid these problems by following a preventive program that includes an EPA-registered sanitizer in conjunction with weekly use of a product that contains Oxone® to keep your pool water sanitized and oxidized.
Special Situations

In addition to regular weekly use, pool owners should also use Oxone® based products for these special situations:
  • Opening Your Pool
    A good starting point is to add an initial dose of 2 pounds of Oxone® per 10,000 gallons of water and then oxidize weekly with 1 pound of Oxone® per 10,000 gallons of pool water. The dose required and the shock frequency will depend largely on the bather load.

  • Before a Party, or to Eliminate Contaminants After Heavy Rains, High Winds
    Add an additional dose or a heavier dose of Oxone® shock oxidizer when bather loads are extremely heavy (for example before/after a party) or following heavy rains or high winds.

  • Closing Your Pool
    Oxone® is also an ideal oxidizer to use during winterizing. It removes contaminants and prolongs the activity of sanitizer residuals throughout the long winter months.
