The Importance of Water Quality in Spa Pools
Maintaining high-quality water in spa pools is critical for both enjoyment and health. Poor water quality can not only make your spa experience unpleasant, but also create an environment where harmful bacteria can thrive. The HSE guidance emphasizes that “water in spa pools should be free from irritant substances, chemicals and infectious microbiological agents at levels which may be harmful to health” [3]. Therefore, regularly monitoring and treating your spa pool water is essential.
Several factors influence spa pool water quality. Water temperature plays a key role. The ideal temperature for microbial growth is between 20-45°C, which is why regular disinfection and monitoring are needed [2, 4]. The pH balance is also essential. According to the HSE, “the pH, total alkalinity, total dissolved solids (TDS), temperature and calcium hardness of water are the main factors in determining the balance of the water” [29]. Keeping the pH between 7.0 and 7.6 helps to ensure that your disinfectant works effectively [18].
Disinfection is a critical part of maintaining water quality. Proper disinfection with chlorine or bromine kills harmful microorganisms and prevents them from multiplying [20]. However, it’s important to monitor disinfectant levels and pH as the “effectiveness of the disinfectant is directly related to the pH of the water” [19]. A balanced water treatment programme that works in combination with filtration helps maintain the cleanliness and clarity of your spa [29, 30].
The presence of organic matter from bathers, like sweat, skin, and hair, can also impact water quality [5]. This is why the guidance highlights that “spa pools have a much higher ratio of bathers to water volume than in swimming pools, so their water has a higher concentration of organic material from bathers” [5]. This organic matter can create ideal conditions for bacteria, highlighting the importance of regular water replacement and filtration. The guidance recommends regular water replacement and thorough draining as well as cleaning [21].
By regularly testing, treating, and maintaining your spa pool water, you can ensure a safer and more enjoyable spa experience. These practices are essential for your health and peace of mind.
