According to the data collected and analyzed in the U.S. by the pool water management company iopool using its EcO sensor 77 percent of pools were not disinfected properly based on the initial sensor measurements.
Pool water quality is a concern for public health, not just aesthetics or comfort. A pool with poor maintenance can breed bacteria and algae that are known to be harmful. California Department of Public Health Division of Communicable Disease Control, for example, recently released an alert regarding neglected pools that can be vectors of West Nile Virus. Even minor maintenance problems can lead to imbalances, without going so far as neglect.
Romain Trigaux is the chief operating officer at iopool. The water turning green is a sign that the pool needs maintenance. However, the problem may have been detected sooner.
This lack of disinfection can be attributed to 58 percent of the cases. Overstabilization is another, less-known, cause of bad disinfection. It accounts for 24% of the cases.
Trigaux says that pool owners add chlorine to improve the water’s quality or for safety reasons. The problem is that the majority of chlorine tablets sold in stores are stabilized tablets. The more you add chlorine, the more stabilizer you need. It is necessary to make sure that the chlorine does not evaporate under UV rays. In excess, the stabilizer can prevent chlorine from working correctly.
The pool will turn green even though the chlorine level is high. In such cases, the iopool app recommends adding chlorine without stabilizer.
It is important to detect this overstabilization as early as possible to adjust the treatment. If you wait too much, the water could turn green. The pool owner is forced to drain the water and refill it.
The overall rate of improper sanitation drops from 77% (average sensor’s first measures) down to 32% (average sensor’s latest measures).
