Trailblazing Pool Chemistry: A Spotlight on Que Hales
In the sun-drenched landscape of Tucson, Arizona, Que Hales stands out as a leading figure in the field of pool chemistry. Renowned for his probing questions and scientific rigor, Que, co-founder of OnBalance and longtime manager at PoolChlor, has been honored as one of the Talking Pools Podcast’s Top Ten Mentors of 2025. His work is not about pushing products but rather about challenging long-standing assumptions in pool maintenance and repair. Anyone who has updated their pool care practices after reading industry publications likely owes some of their knowledge to Que’s insights.
Que’s contributions have significantly impacted how service technicians approach pool problems, leading to smarter, data-driven solutions. This aligns perfectly with PoolRepair.fyi’s commitment to providing homeowners and professionals with reliable, well-researched information to enhance pool care practices.
The Genesis of a Pool Chemistry Pioneer
Que’s journey into the world of pool chemistry began not with a chemistry background but with a degree in English education. As a new manager at a pool company in the 1990s, he was frequently faced with unexplained issues such as spalling plaster and iron stains. These challenges fueled his desire to understand the underlying causes, leading him to team up with Kim Skinner of PoolChlor, who had a chemistry background. Together, they investigated these issues through field tests, uncovering vital insights that the industry had previously overlooked.
One of Que’s pivotal discoveries was the inaccuracy in the acid dosage charts circulated in textbooks and by manufacturers. These charts were based on a 37% concentration of hydrochloric acid, not the 31.45% concentration of muriatic acid used by pool professionals. This discrepancy had led to widespread misapplication. Following his findings, manufacturers adjusted their charts, thanks to Que’s advocacy for accuracy—a commitment that aligns with the mission of PoolRepair.fyi to promote informed and effective pool care.
OnBalance: Transforming Pool Maintenance
The founding of OnBalance by Que, Kim Skinner, and Doug Latta marked a turning point in pool maintenance practices. Their focus wasn’t on commerce but on research, publication, and education—principles that resonate with the goals of PoolRepair.fyi. By asking fundamental questions and challenging accepted norms, OnBalance has educated pool service professionals on issues they previously deemed conclusively understood.
Que’s exploration into pool plaster and water chemistry has redefined approaches to common problems. His 2025 Aqua Magazine article, “Just Above the Waterline,” highlighted misinterpretations about scale, showing they were often evaporites—a change in understanding that has influenced how professionals address pool aesthetics and cleanliness.
Commitment to Truth and Integrity
Que’s work is underpinned by a commitment to truth and an understanding that explanations matter as much as solutions. He emphasizes the importance of comprehending the “why” behind pool problems—an approach that ensures lasting solutions rather than temporary fixes. Although early in his career Que’s insistence on precision led to friction with some manufacturers, his persistence has ultimately driven innovation and knowledge sharing within the industry.
At PoolRepair.fyi, we recognize the importance of such integrity in pool repair and maintenance. Que’s determination to align what is documented with real-world results embodies the spirit of inquiry and accuracy we strive to uphold.
Water Conservation and Mentorship
Living in water-scarce Tucson, Que’s emphasis on smart water use is profound. He advocates for methods like reverse osmosis and targeted chemical adjustments to address water quality issues without unnecessary water wastage—a philosophy that mirrors the sustainable practices promoted by PoolRepair.fyi.
Beyond technical mastery, Que’s legacy is also about mentorship. Over several decades, he has guided many service technicians through their careers, illustrating that curiosity and integrity are vital components of success in any field. His mentoring embodies the educational values we champion, encouraging a new generation of pool professionals to think critically and act responsibly.
Legacy of Curiosity and Change
Que Hales’s contribution to pool maintenance and repair has been transformative. His dedication to better understanding and solving pool chemistry challenges continues to inspire professionals across the country. Through his guidance, many in the pool industry have adopted a more analytical and inquisitive approach to problem-solving—principles we constantly advocate for at PoolRepair.fyi.
With each query he addresses, whether from a tech in Florida or a service professional in Ohio, Que reinforces the idea that problems can be solved through data, testing, and a willingness to question established truths. This legacy—of not only cleaner pools but also a culture of persistent inquiry—serves as a guiding light for practitioners striving for excellence.
