Thank You Lorraine W. for contributing your questions to our blog.  We’ve posted our discussion so that Red Square Pools “Blog Heads” can offer their constructive feedback on usage of Hydrogen Peroxide and/or UV light as methods for oxidation.

I’ve done some research on Hydrogen Peroxide (H2O2) as an oxidizer and I’m not convinced this is a strong play for residential pools.  Apparently H2O2 interacts with and oxidizes organic materials BUT DECOMPOSES with UV light.  If your intent is to combine a UV system with H2O2 system it seems to be counter intuitive.

If you decide to pursue H2O2 as a primary oxidizer the ratio is 1 cup of 35% H2O2 for every 500 gallons of water.  When we last discussed the size of your pool we were in the neighborhood of 7,000+ gallons therefore using roughly 1 gallon of 35% H2O2 should suffice.
NOTE:  ratio for Peroxide to water is 1 cup 35% H2O2 to 500 gallons of water
I am uncertain as to the frequency of adding H2O2 however I’m certain you can test your levels weekly with Peroxide test strips to maintain recommended concentration levels measuring between 50 and 100 ppm.
As far as UV light systems we are recommending the SpectraLight SL-500 system for your pool design.  They cost $2,199.00 for the system and would require installation by a licensed pool contractor familiar with the system.  The manufacture does recommend a minimum 0.5 ppm level of Free Available Chlorine to maintain balanced water compared to 2-3 ppm with chlorine pools.  Since this pool will be indoors your chlorine levels should be easy to stabilize and maintain.  If chlorine is not an option, Spectralink’s website suggests the H2O2 CAN BE USED however my research indicates you may find you’ll have to add more H2O2 to maintain recommended levels at 0.5 ppm.   Chlorine, in my opinion, is a far better oxidizer as it is far more stable.
