ORP and Oxidation

Oxidation/reduction potential… We’ve all heard the term, but what does it really mean? We’ll see that it is, essentially, a relative measure of the desired “work value” of our pool sanitizer  and a pretty darn’ good one at that. But first, let’s dissect the term itself.

Hi All! Test posting an edition of the Pumproom Press (PrP) to see how this may work out going forward. Enjoy! ~RB

Seasons Greetings PPOAers!

Hope this holiday season finds you joyful, or at least headed in that direction. And speaking of direction, I thought that I would pass along a little controller related direction from my friend, Clemente Rivera on the care and longevity of controller sensors. You can find his post in the forum column on the main page at Sensor Technologies - How Long Do They Last?, or by simply clicking on this link ( He provides some good, practical direction for maintaining accurate probe sensitivity. Hope you find it useful!

Whatever hemisphere you are in and however you celebrate, have a blessed holiday season and a prosperous new year!

As we approach the pool "seasons" end with the coming of Labor Day weekend and the opening of the new one down under, I hope y'all have had and will have a safe and healthy summer.

Here's my recommendation for a quick post or preseason (re)read of a 2012 AI Tech Talk post titled Quality Control by Matthew Griffith, of the Griffith Aquatic Group. I re-post this to reaffirm the importance of ORP in measuring and controlling the qualitative work of your pool sanitizer, and to prompt you to keep a lookout for news from the on-going study and AIConnect Discussion which supports the "decades worth of scientific research studies show(ing) the relationship between ORP and bacterial inactivation" mentioned by Matthew. Kent Williams wrote exhaustively for the PPOA and otherwise on the same topic (see my previous post) due largely to its importance in managing water, but also to filter out the misconception surrounding it. What Dr. Lund and others have proven about the relationship between ORP and the inactivation rates of microorganisms, we shall soon see in common practice.

Hey y'all! Hope your Christmas break was joyful and that your "in-season" or "off-season", depending on which hemisphere you're in, is equally joyful. No matter the season, as a member of this group, water quality of the pools under your charge is of the highest concern. Kent Williams and the PPOA have always endeavored to support us in that cause with clear, unbiased science based writing designed to address the many fassets of pool operations. In keeping with this goal, I bring you another of his archived writings that I have personally found to be essential reading in the process of understanding and applying the control of oxidation; ORP and Oxidation. Take a moment to read, pass on, or ask your mates questions regarding this important topic. EnJOY! ~RB

A mid-summer examination of pH from Kent Williams' Tech Talk: What is the Ideal Value? Some pool-guy philosophy with a look at pH choices.

Check out the updates on a study which will be of interest to us all.

This technical discussion, "Breaking Point" on LinkedIn could now qualify as a Webinar! Super resource(s) for Operators! Most definitely worth a look see.

Hello again Chlorineheads! Just in case you've lost touch with the outside world in recent weeks due to your preparations for the imminent swim season, I thought I would pass on these two recent AI postings on Cyanuric Acid use. Read, or re-read first: Then please read:, Kent Williams and Rich Youngs clarifying reply. If you use, or are considering using CYA, you need to read these posts! Then go back in the pumproom! Have a safe and healthy season y'all! ~RB
