Bob Lowry a Legend of the Industry: All Podcast Episodes with Bob Lowry

Bob Lowry passed away on November 17th, 2021 and a true legend has left the pool and spa industry. He was the author of over 23 books but this has to be one of his most relevant and shortest books coming in at just 19 pages thick. But it is packed with so many essentials on residential pool chemistry that you will want a copy to carry in your service truck. Bob Lowry has been in the industry for over 47 years and is the Lead Consultant at Lowry Consulting Group, leads the Pool Chemistry Training Institute, and has created the Certified Residential Pool & Spa Certification Program.

Bob Lowry teaches Target Chemistry and here are his recommended target numbers. Not a range but a specific number to shoot for.

Sanitizer 3.0 ppm
After the alkalinity & pH are brought into range, the next adjustment is the sanitizer. Liquid Chlorine or Bleach is the most common and least expensive of the available sanitizers. The acceptable range is 1.5 - 3 ppm, though 4 - 5 ppm is absolutely fine. A commercial spa should be maintained at much higher levels - 5 - 6 ppm. Bob Lowry has the Target at 3.0 ppm so you should always aim for that for your residential pool.

A residential pool should be maintained at 3.0 ppm. The higher levels ( 4 - 5 ppm) should be established, prior to a large party or heat spell. Try not to allow the levels to drop below 3 ppm, as this will prevent the need to shock or take other corrective action after the party.

ALKALINITY 90 ppm
There are a number of factors that contribute to the "balance of the water." The most important is the pH and the alkalinity. The alkalinity is the ability of the water to buffer the pH (or buffer chemicals that may affect the pH). The alkalinity is like an auto-pilot or cruise-control for the pH.

If the alkalinity is out of the acceptable range, then any small factor will cause a wild swing in the pH. This is called "pH bounce." Because of this, alkalinity is the first thing that should be brought into line when balancing the water.

An ideal range for the alkalinity is 100-120 ppm (though 80 - 140 ppm is acceptable).

pH 7.5
The pH of the water determines if it is acidic or basic. Either extreme can have disastrous effects on the pool finish, equipment, or plumbing. When the pH is out of range, bathers may complain of eye discomfort or other ailments.

An acidic pH will cause the water to become aggressive. It will etch the plaster and cement finishes around the pool. Worse yet, it will dissolve the metallic components of the pool. The most expensive metallic component is the copper heat exchanger within the pool heater.
