No Comments We finished out the year of 2011 at PoolCorp’s Superior Pool Products building in Anaheim this past Thursday and Friday (December 8-9). The CPO students were energetic and ready to learn about swimming pool operation, and did quite well on the exam. Thanks again, to PoolCorp and to the staff in Anaheim for all your hospitality and support throughout the year. And a BIG “thanks” goes [...]
September 27th, 2011 by Steve No Comments Chlorine is an element of nature – it is number 17 in group 17 (Halogens) on the Periodic Chart of the Elements. It is a gas in its elemental form. Using various processes, different chlorine compounds are manufactured which we use in the swimming pool industry: Sodium Hypochlorite (Liquid Chlorine) Calcium Hypochlorite (Cal Hypo) Lithium Hypochlorite TriChlor (trichloro-s-triazinetrione) DiChlor (sodium dichloro-s-triazinetrione) To protect chlorine [...]

March 13th, 2011 by Steve No Comments 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 [...]
