The table below shows approximate inactivation times for microorganisms in properly maintained, chlorinated pool water. The reference conditions are close to CDC (U.S. Centers for Disease Control and Prevention) recommendations: free chlorine around 1 ppm, pH 7.2–7.8...
Automation: Who Monitors the Water When You Are Not There? The water in a swimming pool is a dynamic environment that changes every minute. Swimming, hot sun, or rain instantly affect pH and chlorine levels. Even the most professional service cannot be present at the...
How can you really know if pool water is safe? Water clarity is just the tip of the iceberg. Beneath a perfect appearance, invisible processes can occur: excess chemicals or bacterial growth. To know the true water condition, various monitoring methods are used....
Alkalinity Low alkalinity (below 80 mg/L): pH becomes unstable. Any external factors — rain, adding chemicals, swimming — can cause sharp pH fluctuations. High alkalinity: pH becomes difficult to adjust. Even adding acid lowers it slowly and reluctantly. Normal range:...
The Myth of Water Clarity: Why Clear Water Can Be Unsafe Water transparency is a physical characteristic (absence of suspended particles) that does not guarantee biological safety. Microscopic Pathogens The main danger comes from bacteria (e.g., E. coli or Pseudomonas...
