Next Episode: Understanding Shotcrete (w/ Bill Drakeley, Watershapes University)

00:00 - An extra-long intro, complete with Jarred's new microphone and some housekeeping topics.

01:24 - Housekeeping: We're teaching with Watershapes University. WU C3611, November 12 and 13 in Las Vegas: Essential Plaster Workshop. And we're participating in Swim Across America, September 24 in Dallas. You can contribute to our team at swimacrossamerica.org/goto/orenda.

03:38 - Check out the chlorine and CYA chart here: https://blog.orendatech.com/chlorine-ph-and-cya-relationships

04:55 - When you introduce CYA into the water, pH no longer controls the strength of chlorine (%HOCl)!!

08:23 - Chlorine strength is determined by the FC:CYA ratio. It's only a matter of time until health departments recognize this.

10:58 - At a high enough pH, OCl- will break away from CYA and can be destroyed by sunlight. Focus on your pH ceiling to avoid this fate.

13:50 - Simplifying the complex

15:36 - The Orenda program takes these overlapping factors into account, so you do not need to understand all of the chemistry. We've taken things into consideration for you. Just follow the plan and the chemistry will behave.

18:05 - Paradigm shifts are never comfortable

18:42 - Summary. Thanks for listening!
