The response of bacteria to temperature is not a simple "live or die" situation, but a gradual process. Below 40°C: Bacteria can still exist actively. 37–40°C is precisely the commonly used temperature range for many spa hot tubs, which means that: Normal operating temperatures cannot kill bacteria.

Before entering the tub, lightly apply a layer of natural hair oil (such as coconut oil, argan oil, or jojoba oil) to the ends of your hair. These oils form a protective film on the outer layer of the hair, reducing the erosion of hot water and chemicals.

The ideal energy-saving temperature for a whirlpool hot tub should be maintained between 34℃–37℃. This range ensures a comfortable spa experience while avoiding unnecessary energy consumption. If the equipment is operated outdoors or in cold climates, the minimum temperature can be increased by 1–2℃ to prevent excessive heat loss.

Unsafe. When the water in a swim spa hot tub becomes cloudy, it often indicates a malfunctioning or overloaded disinfection system. At this time, bacteria, mold, and algae will multiply rapidly. Common pathogens include: • Pseudomonas aeruginosa • Legionella • Candida, mold

Under most normal operating conditions, it is recommended to clean the swim spa hot tub filtration system every 1-2 weeks. This frequency applies to the following situations: • Moderate usage frequency • Relatively standardized water quality management • Few users • Water remains clear for extended periods

As long as the discoloration is not due to plating peeling, but rather surface deposits or slight oxidation, the nozzle can regain its bright white color through systematic cleaning and maintenance. Daily Gentle Cleaning Method (Suitable for mild yellowing) Materials needed: White vinegar, warm water, soft cloth or sponge.
