Chlorine used as a disinfectant in swimming pools can be toxic to humans, causing many to look for alternative means of sterilization. You may use hydrogen peroxide, or H2O2, in place of chlorine to keep your water clean while maintaining an environment that is nontoxic and safe from bacteria. You can establish and maintain the proper balance of hydrogen peroxide in your pool by taking a few simple steps.
Determine the gallon capacity of your pool, if you don't know already know it. If necessary, consult the pool supply company you bought the pool from. You can also use different formulas to calculate your pool's gallon capacity, depending on your pool's shape (see Resources).
Measure 1 cup of hydrogen peroxide into your liquid measuring cup for every 500 gallons of water in your swimming pool, and add this directly to the water. For instance, if your pool's capacity is 12,000 gallons, you will add 24 cups of hydrogen peroxide. Use gloves and protective goggles when adding the hydrogen peroxide.
Test the concentration of peroxide in your swimming pool using your test strips, following the packaging instructions. (They are typically used exactly as chlorine test strips.) Your target concentration is 30 parts per million, which may be determined by following the guide to reading the color scale on the test strips.
Turn off your swimming pool's pump after you have added the hydrogen peroxide. Leave it off for a 24 hours. Allow the water to sit, undisturbed, before turning the pump back on. Do not use the pool during this time period.
Check the balance of your pool weekly using the test strips, and add hydrogen peroxide accordingly.
