H2O: Pure water: Pool Chemicals

There is a devise one installs on the filter system that generates Pure Water with electrolysis. The sanitizers produced are oxygen and hydrogen and copper for algae control. I have taken care of pools for 30 years and I feel that chlorine is the only sanitizer that works. Being from the desert where temperatures are high, water is vulnerable. Algae grows in warm water and the temperature of the pool water reaches 90 degrees plus, a perfect haven for algae. Copper is great for algae control, but do oxygen and hydrogen really sanitize the water? Where water temperature is stable, it might work, but chlorine has been the choice of sanitizing water that comes from our taps for drinking. I am for pure water, but sanitizing is important to kill viruses and pathogens and chlorine works. Enjoy the pool with whatever works, but be sure to sanitize the water.
