Most people experience reduced stress, improved sleep, and more stable mood after 1–2 weeks of continuous use. This is a result of the gradual restoration of cortisol levels to a balance. It is important to note that the stress-reducing effect of continuous use of the whirlpool spa hot tub is cumulative, not a one-time effect.

The water level in a luxury swim spa hot tub is not necessarily better the higher it is, nor should it be too low. Generally, when using a luxury swim spa hot tub in a home or private setting, the water level should be controlled at 70%-90% of the total tub depth.

The space required to install a swim spa hot tub depends on its type, size, and usage environment: • Compact: At least approximately 5.5m × 3m; • Standard: Approximately 6.5m × 3.5m; • Large or dual-zone: At least 8m × 4m; • Equipment and maintenance space: It is recommended to add an extra 1m safety margin to the main dimensions.

The design temperature of a swim spa hot tub typically doesn't exceed 40°C, while boiling water reaches 100°C. This high temperature can severely impact the heating system and other tub components. Adding boiling water not only harms the equipment but also affects water quality. The water in a swim spa hot tub needs a certain chemical balance to remain clean and safe.

The frequency of disinfection for a whirlpool spa hot tub depends on: • Usage frequency • Number of users • Water volume and circulation system design • Whether chlorine or bromine tablets are used to maintain daily water quality For ordinary household users, thorough disinfection at least once a week is a basic requirement for maintaining water quality safety.

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
