Keeping your family safe starts with crystal-clear, balanced pool water. In Columbus, OH, fluctuating temperatures and heavy pool usage can challenge even the most diligent homeowners. That’s why understanding LSI testing—and using it as part of a regular pool maintenance plan—is critical to protecting your investment and your loved ones.
LSI stands for Langelier Saturation Index, a scientific formula that measures the balance of your pool water’s chemistry. It considers six key factors: pH, alkalinity, calcium hardness, temperature, total dissolved solids, and saturation index.
Instead of just focusing on pH or chlorine levels alone, LSI provides a comprehensive snapshot of whether your water is corrosive (which can damage pool surfaces and equipment) or scale-forming (which can clog filters and shorten equipment life).
Maintaining an LSI between -0.3 and +0.3 is the industry gold standard—anything outside that range can lead to serious problems for your pool and unsafe swimming conditions.
At 614 Pools, LSI testing isn’t just a feature—it’s standard on every pool visit.
Our Certified Pool Operator (CPO®) technicians are trained to test all critical chemical levels, and we use custom software to calculate exact chemical dosing based on your pool’s size, usage, and environmental factors.
Every adjustment is reviewed by a Service Manager, ensuring that your water stays safe, balanced, and aligned with the LSI standard. This attention to detail protects your vinyl liner, keeps your equipment running longer, and—most importantly—keeps your family safe while swimming.
