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 [...]

How Much D.E. Do You Put In That Filter?
