1. Use appropriate chemical disinfectants 1) Chlorine disinfection Recommended chlorine concentration: 1–3 ppm (parts per million). 2) Bromine disinfection Recommended bromine concentration: 3–5 ppm. 3) Hydrogen peroxide disinfection Recommended concentration: 10–20 ppm. 2. Ultraviolet disinfection

Children over 2 years old: Can soak briefly in a specially temperature-controlled hydrotherapy hot tub. Water temperature not exceeding 37.5°C (99.5°F); time limited to 5–10 minutes; adult supervision is required.

A steam shower room is a closed bathroom device that integrates regular hot water showering with steam generation. It typically consists of a sealed shower enclosure, a steam generator, an electrical control system, a ventilation system, and a multi-functional control panel.

Total Alkalinity (TA) – The First Step to Balancing Total alkalinity measures water's buffering capacity against pH changes; it can also be understood as the "foundation of water quality stability." • Ideal Range: 80–120 ppm. If alkalinity is too low, pH will fluctuate frequently; if alkalinity is too high, pH adjustment will become difficult.

If multiple jets are turned on, the increased water flow will also increase the pump load, which may actually reduce the heater's heating efficiency. This is because the heater requires a certain water flow rate to effectively transfer heat, and excessive water flow may dilute the heat transfer effect.

Impact is a crucial step in ensuring water quality and proper functioning of the luxury spa hot tub. The impact time is generally 10–20 minutes, which can be extended to 30 minutes for larger water volumes or complex systems. Frequency is recommended once a week or after each use, depending on the actual situation.
