Understanding and Managing Cloudy Water in Your Hot Tub
Causes of Cloudiness
Cloudy hot tub water typically results from particles too small for the filter to capture, often introduced by bathers. Common sources include:
- Environmental Debris: Dirt, grass, and dust carried in by users.
- Organic Matter: Dead skin, body oils, and sweat add to cloudiness.
- Man-made Contaminants: Cosmetics, lotions, and detergents from swimsuits.
- Other Factors: Heavy bather loads and low sanitiser levels can exacerbate cloudiness.
Solutions for Cloudy Water
- Testing and Balancing Water Chemistry: Regularly check pH, alkalinity, and sanitiser levels to maintain balance.
- Shock Dosing: Use chlorine or non-chlorine shock treatments to oxidise impurities, helping to clear the water.
- Filter Maintenance: Rinse filters regularly and use a filter cleaner monthly. Replace filters every 12-24 months for optimal performance.
- Clarifiers: These products bind small particles, making them easier for the filter to catch.
Prevention Tips
- Shower Before Use: Rinse off without soap to reduce contaminants.
- Avoid using lotions, cosmetics, and detergents in the hot tub.
- Use a foot bath before entering to prevent tracking in dirt and grass.
- Keep the cover on when the hot tub is not in use to prevent debris from entering.
- Regularly use shock treatments and clarifiers to maintain clarity.
Hot Tub Water Conservation Tips
Monitoring Water Use
Install a water meter specifically for your hot tub to monitor usage, manage costs, and track any changes that could indicate a leak.
Preventative Maintenance
Regular maintenance is far more cost-effective than reviving a neglected hot tub. Keep your water balanced and clean filters to extend water quality and reduce the need for frequent refills.
Minimising Water Loss
- Use a hose with a trigger nozzle to control water flow during refills.
- Repair any leaks promptly to prevent unnecessary loss.
- Avoid excessive splashing to reduce the need for top-ups.
- Consider reusing drained water for gardening purposes if chemical levels are safe, but consult a horticulturalist for delicate plants.
Reducing Evaporation
- Always keep the cover on when the hot tub is not in use.
- Maintain a lower water temperature, especially during hot weather, to reduce evaporation.
