When the swim spa hot tub is not used for extended periods, "periodic heating" is more scientifically sound than "continuous heating." Heat 1-2 times per week. Raise the water temperature in the swim spa hot tub to approximately 35°C and keep it circulating for 1-2 hours to effectively inhibit bacterial growth.

If used properly, generally not. • Prolonged soaking: For example, soaking for more than 40 minutes continuously can indeed cause dry skin. • Regular, long-term use: Using the hot tub several times a week for a reasonable amount of time can actually promote skin metabolism and blood circulation, benefiting skin health.

It is not necessary to add chlorine daily, but it is necessary to monitor it daily. It is recommended to test the chlorine level daily and replenish chlorine when the value falls below 0.5 ppm, maintaining the free chlorine level between 1 and 3 ppm. If the water is only used a few times a week, the decision to add chlorine should be based on the actual water quality.

The optimal growth temperature for fungi (such as Candida, Aspergillus, and mold) is approximately 25°C to 37°C, while the water temperature in a swim spa hot tub is typically set between 30°C and 39°C. If water quality is not properly managed and the circulation system is not cleaned regularly, microorganisms can thrive.

Studies have shown that an unshowered person entering a hot tub or luxury swim spa introduces an average of 1-2 grams of organic matter. While this amount may seem small, in a circulating heated environment, these substances quickly break down, creating odors, foam, and even a breeding ground for bacteria.

The answer is: not necessarily. For most homes, above-ground installation is the most common, safest, and most efficient option. It requires no excavation or waterproofing modifications. As long as the ground is flat and meets load-bearing standards (generally 500-800 kg/m²), it can be installed directly.

Modern swim spa hot tubs are designed with safety in mind. High-quality products often feature non-slip textured floors, high-friction materials, or special sandblasting processes to effectively reduce the risk of slipping when standing.

The answer is: with proper use and maintenance, it is not. Modern swim spas often have built-in intelligent temperature control modules that monitor water and ambient temperatures in real time. If the temperature approaches freezing, the system automatically enters "anti-freeze mode": • Activates the circulation pump; • Provides moderate heating; • Disables unnecessary energy consumption.

Family Swim Spa Tub (for 3–6 people) • Length: Approximately 4.0–5.5 meters • Width: 2.0–2.3 meters • Features: This is the most popular family model. Typically equipped with multiple massage nozzles, sitting and lying areas, and a swimming area, they can accommodate the entire family, making them an ideal choice for family leisure.

The chemical addition sequence should strictly adhere to these principles: 1. Adjust alkalinity first 2. Adjust pH second 3. Adjust hardness 4. Remove metals 5. Add stabilizer 6. Add disinfectant 7. Perform maintenance by shock treatment

The fundamental reason why chlorine and hydrochloric acid cannot be mixed: a violent chemical reaction. Although chlorine and hydrochloric acid both play important roles in swim and spa pool water treatment, they should never be mixed directly, especially in their undiluted, concentrated form, which is extremely dangerous.
