  • Self-Serving Pseudo-Science (w/ Terry Arko)
    Apr 10 2024

    00:00 - Introduction

    03:13 - Myth 1: ANSI-11 Standards NEVER allow water chemistry outside the ranges

    05:12 - Myth 2: It's important to give water what it wants to "make water happy"

    10:01 - Myth 3: The pH is constantly increasing outside of the acceptable range stated in Standard 11, and there are no options

    14:40 - Myth 4: Water balance indexes indicate whether water is scaling or corrosive to surfaces and metals

    20:12 - Myth 5: In a pool using chlorine and cyanuric acid, keeping the pH in the acceptable range is not important. Chlorine is controlled by the CYA.

    29:03 - Myth 6: To control algae, it is important to maintain a certain ratio of CYA to free chlorine

    33:54 - Myth 7: Chlorine lock

    36:15 - Myth 8: Chlorine demand is caused by high phosphates and nitrates

    37:45 - Myth 9: Using bleach in a pool does not raise pH

    Mar 15 2024

    00:00 - Introduction

    01:00 - ORP is a water quality subject

    02:39 - Chlorine oxidizes by stealing electrons

    04:25 - Why is ORP used in swimming pools?

    06:26 - Is ORP measured as conductivity?

    07:21 - Factors that affect ORP - pH, CYA, water temperature

    08:23 - pH and ORP

    11:19 - ORP accuracy is based on fixed pH and chlorine levels

    13:22 - Cyanuric acid and ORP

    14:24 - Water temperature and ORP

    16:20 - Ways to increase ORP

  • Chlorine's pH impact in swimming pools (w/ Terry Arko)
    Feb 21 2024

    00:00 - Introduction

    01:12 - Old habits and beliefs about chlorine and acid

    11:07 - Our bodies produce HOCl too

    12:13 - HOCl will become HCl (aka muriatic acid)

    16:00 - Cal hypo (calcium hypochlorite)

    21:30 - Sodium Dichlor (dichloro-s-triazinetrione)

    21:46 - Trichlor (tricoloro-s-triazinetrione)

    26:36 - Saltwater chlorine generators (SWG)

    30:43 - Chlorine gas (Cl2)

  • Is the Orenda Calculator™ true to the LSI formula? Or different?
    Feb 14 2024

    00:00 - Introduction

    01:35 - We have learned from past mistakes

    04:40 - The history of the Orenda Calculator™ formula

    05:51 - Dr. Langelier's original formula = pH - pHs

    10:47 - Revisions to the LSI in 1942, 1964, 1965 and beyond

    12:32 - Technology is not limited by reference charts

    14:29 - The LSI charts today are based on the updates by John Wojtowicz

    17:22 - Wojtowicz wrote about the pH Ceiling concept

    19:19 - The most precise LSI calculator in the world
