The water should be disinfected with at least 0.5 mg of chlorine per liter. The pH-value should remain within the range of 6.8 and 7.8. The generally high temperature in whirlpools, combined with the water movement caused by air or water injection, often cause chlorine evaporation. In addition, the limited buffering ability in smaller whirlpools changes the pH-level, disintegrating the disinfecting effect of chlorine. Whirlpools are also generally more heavily laden than general pools (more people per volume), increasing the use of chlorine. Therefore it is imperative to intensively check the chlorine levels and the pH-value.
