May 05, 2025 By Aditya Rao

Owning an outdoor hot tub is a luxurious experience, but it requires regular maintenance to ensure longevity, safety, and optimal performance. This monthly care guide will help you keep your hot tub in pristine condition, providing a relaxing and hygienic environment.

Monthly Maintenance Tasks

1. Water Quality Management

Test Water Chemistry Weekly: Use test strips or a liquid test kit to check pH (ideal range: 7.2–7.8), total alkalinity (80–120 ppm), and sanitizer levels (chlorine: 1–3 ppm, bromine: 3–5 ppm). Adjust as necessary.
Perform a Non-Chlorine Shock Treatment Weekly:
1. Preparation: Wear chemical-resistant gloves and safety goggles.
2. Test and Adjust pH: Ensure the pH is between 7.2 and 7.8.
3. Measure the Shock: For a 250-gallon hot tub, use 1–2 ounces of non-chlorine shock.
4. Add the Shock: Slowly add the shock near a water inlet with the circulation pump running.
5. Circulate and Wait: Allow water to circulate for at least 20 minutes before use.
Check Water Level: Ensure water levels keep the pump and heater functioning correctly. Top off as needed.

2. Filter Maintenance

Weekly Rinse: Rinse filters with a garden hose to remove debris.
Monthly Deep Clean:
1. Soak filters overnight in a filter-cleaning solution.
2. Rinse thoroughly.
3. Dry completely before reinstalling.

3. Hot Tub Cover Care

Inspect for cracks, waterlogging, or mildew.
Clean the Cover:
1. Remove debris with a soft brush or cloth.
2. Wash using mild soap and water.
3. Rinse and dry completely.
4. Apply UV-protectant to prevent cracking and fading.

4. Jet and Surface Inspection

Activate jets to ensure proper functionality; check for blockages.
Wipe hot tub shell with a non-abrasive cloth and mild cleaner.

5. Cabinet and Surroundings

Inspect cabinet for wear, pests, or water damage.
Clear debris and ensure proper drainage around the hot tub.

Seasonal Considerations

Quarterly Drain and Refill: Drain and clean hot tub every three months.
Winterizing Tips: Protect hot tub during colder months by insulating pipes and using a thermal cover.
