Preparing for a swim spa tub treatment is a key step in achieving a safe, comfortable, and effective experience. Preparation includes: • Equipment inspection • Water quality management • Personal preparation • Post-treatment procedures

Light Home Use • Usage frequency: 1-2 times per week, with a small number of users (1-2 people). • Recommended draining cycle: Every 3-4 months. Swim spa tubs with light use have relatively less water contamination, and disinfectants can maintain water quality for a longer period.

• Large outdoor whirlpool hot tubs (>2000 liters): Recommended starting dosage of 3–4 chlorine tablets. • Medium-sized home whirlpool hot tubs (1000–1500 liters): Recommended dosage of 1–2 tablets. • Small single-person tubs (<800 liters): 1 tablet is sufficient.
