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.

General Recommendation: Flush the swim spa hot tub after every 3 to 5 uses, or at least once a week. This achieves a good balance between maintaining water quality and maintenance costs.

Using excessively high concentrations of hydrogen peroxide in swim spa hot tubs may corrode or irritate bath equipment, pipes, and human skin. Therefore, the concentration must be strictly controlled during disinfection; a low concentration (1%~5%) added in stages is generally recommended.

In public swimming pools or spas, hygiene standards generally require users to rinse thoroughly before and after entering the pool/spa to reduce the risk of contamination and cross-infection.

According to expert advice, if a swim spa tub is not regularly maintained (such as adding disinfectants, cleaning filters, testing water quality, etc.) for a long time, the recommended vacancy time should not exceed two weeks. If this time limit is exceeded, the possibility of water quality deterioration is greatly increased, and it may need to be replaced and thoroughly cleaned.

If chlorine shock treatment is performed for two consecutive days, the residual chlorine concentration in the water may be too high. High concentrations of residual chlorine not only produce a strong chlorine smell, but may also irritate the skin and eyes, and even cause respiratory discomfort.
