For example: • Using untreated hard water can lead to scale buildup, clogging nozzles and pipes; • Neglecting water balance can corrode the inner tank and electric heating system; • Failure to replace the filter for a long time can allow bacteria to grow, reducing the spa's effectiveness.

Too low a temperature will weaken the relaxing and soothing effects; too high a temperature may cause an increased heart rate, dehydration, or dizziness. 36°C to 40°C is the ideal temperature range for most people using a spa jacuzzi.

If your spa hot tub has the following characteristics, it is not recommended to use it as a shower: • The bathtub is made of thin acrylic walls, which are not suitable for standing; • It lacks an anti-slip bottom or safety handles; • Electrical components are exposed or close to the shower head area;

The water temperature in a regular bathtub gradually decreases, while a spa hot tub is equipped with a constant temperature heater, maintaining a constant temperature. This means the body's sweating response lasts longer, resulting in greater water loss.

Under normal circumstances, spa jacuzzi bathtub water should be clear, soft, odorless, and have a natural feel. If a "slippery" feeling occurs, it usually means that the chemical balance in the water has been disrupted or organic matter has accumulated.

It is generally recommended to maintain the water temperature between 36℃ and 40℃. Young, healthy individuals with normal circulatory systems can soak for 25-30 minutes; the elderly or those with weak cardiovascular systems are advised to limit it to 15-20 minutes.
