Intro02:15 - How do we get rid of combined chlorine? Do we just let chlorine do its thing?02:49 - Two categories of how to reduce combined chlorine: chemically and physically.03:30 - Two chemical options: breakpoint chlorination and supplementing chlorine with enzyme or a non-chlorine oxidizer shock. But enzymes and non-chlorine oxidizers do not directly reduce combined chlorine...only chlorine can.15:06 - Physically removing combined chlorine is done with secondary systems.  Oxidizers and UV sanitizer.  Ozone and AOP are oxidizers that destroy both nitrogen compounds and formed chloramines. UV can only destroy formed chloramines.23:43 - If you have a heavy bather load, a secondary system makes a lot of sense.24:30 - Being proactive means finding the source of nitrogen and addressing that.  Check deck cleaners, any algaecide or other product containing ammonia (or ammonium) and keep them out of your pool.------------------------------------Connect with Orenda TechnologiesWebsite: https://www.orendatech.comBlog: https://blog.orendatech.comYouTube: https://www.youtube.com/user/OrendaTechnologiesFacebook: https://www.facebook.com/orendatech/Instagram: https://www.instagram.com/orendatechnologies/
