  • Strange Stains

    Though many stains fall into similar categories, some are so odd that they almost seem to have come from another dimension

  • Calcium Phosphate Scale

    Though calcium phosphate scale is a newly discovered problem for the swimming pool industry, it has long been recognized in the boiler industry, where the practice of using polyphosphonates to control calcium carbonate scale is often used.

  • Saturation Calculation

    Whether the job involves starting up a brand-new plaster pool or maintaining chemistry in an old fiberglass vessel, pool professionals know that a proper understanding of water balance is essential.

  • The Long Haul

    Gary Gripp’s story begins like so many others.

  • Borate Chemistry

    Borates are found throughout nature, and are refined for a variety of diverse applications.

  • Everyone on Deck

    Often, a deck is the most visible part of the backyard, so you don’t want to neglect it with a finish that looks like a sidewalk.

  • Perfect Balance

    Since the 1960s, the pool industry has relied on the Langelier Saturation Index to achieve balanced water.
