The Acid Column Myth

– The following article is from Kim Skinner — part of the research team of onBalance.  I received this via email from Kim a few days ago.  Enjoy. __________________________________________________________________________ By Kim Skinner. Although onBalance debunked the Acid Column Myth in the Journal of the Swimming Pool and Spa Industry many years ago, we still regularly get asked in our trade show chemistry classes about its […]

Total Alkalinity – What is it exactly?

There are several phrases and terms used to describe Total Alkalinity (TA): The buffering capacity of water Water’s ability to neutralize acid The pH stabilizer The ability of water to resist a change in pH A measure of the total of hydroxide ions (OH–), carbonate ions (CO3–) and bicarbonate ions (HCO3–) in water The pH anchor These are all correct.  As you know, TA is […]

pH Adjustment Dosage Charts

A swimming pool in optimium performing condition–one that is healthy and safe as possible–should be the goal of every Certified Pool Operator.  And keeping the pool water balanced is a key factor in achieving this goal.  Here’s the pool water chemistry parameter guidelines that we use — they are also on page 258 of the CPO handbook.  And here is the chemical adjustment guide — page 260 […]

Baking Soda or Soda Ash?

When we discuss pool water balance in our CPO classes (as we did this past Thursday and Friday in Anaheim, March 10-11, 2011),  I make a statement like:  “In our industry, we add Sodium Bicarbonate  (baking soda) to raise the Total Alkalinity.” In our CPO Handbook (on page 360), the “Chemistry Adjustment Guide”  indicates that it will take 1.4 pounds of BiCarb to raise the […]

Pool Water Chemistry – Disinfection and Balance

We had another full house in San Diego at our CPO class this past Thursday and Friday, September 9-10.   It was an interesting group of  property managers, facility maintenance personnel, pool guys, and a few newcomers to the industry. Pool water chemistry — understanding it is most important for the Certified Pool/Spa Pool operator.   It can  can be thought of in two distinct and […]

Keeping Records – A Never Ending Task

We had our second installment of our CPO presentation for Archstone Apartments.  This past Thursday and Friday, September 2-3,  we were at their regional HQ in Santa Ana – a first class facility in all aspects!  Everyone was very professional in dress and manner and spoke  as if they took pride in their position at Archstone and for working in such a beautiful facility. The CPO […]
