How to Keep Your Hot Tub Water?

Just imagine a crisp evening, stars above, and you’re ready to slip into the warm, soothing embrace of your hot tub. But as you peel back the cover, you’re met with cloudy, murky water that’s far from inviting. It’s a scenario no hot tub owner wants to face. 

The secret to transforming your hot tub into a crystal-clear oasis lies in proper maintenance and care. In this blog post, we’ll dive into the essential tips and tricks on how to keep your hot tub water as clear as a mountain stream, ensuring you can enjoy your relaxation haven to the fullest.

Why It is Important to Keep Your Hot Tub Water Clear?

Keeping your hot tub water clear is crucial for several important reasons:

  1. Safety: There is no doubt that cloudy or dirty water can make it difficult to see the bottom of the hot tub, which could hide potential hazards such as sharp objects or debris. Clearwater enhances safety by allowing you to see and navigate the hot tub more easily.
  2. Water Quality: It is a sign of good water quality. When your hot tub water is clear, it is more likely to be free of harmful microorganisms, bacteria, and algae that can cause infections and waterborne illnesses.
  3. Chemical Balance: It is an indicator that your hot tub’s chemical balance is correct. When the water is balanced with the right pH, alkalinity, and sanitizer levels, it is less likely to develop issues like scaling, corrosion, or water cloudiness.
  4. Aesthetic Appeal: It is visually appealing and more inviting for users. It enhances the overall experience of soaking in a hot tub, creating a more relaxing and enjoyable atmosphere.
  5. Longevity of Equipment: It can extend the life of your hot tub equipment, including pumps, filters, and heaters. Proper water chemistry reduces the risk of corrosion and scale buildup on these components.
  6. Chemical Efficiency: It is easier to maintain chemically. When water is cloudy, you may need to use more chemicals to correct imbalances or clear up issues. Clear water allows for more efficient chemical use, saving you time and money.
  7. Comfort: Cloudy or dirty water can be uncomfortable and unappealing for users. Clean and clear water enhances the comfort and relaxation experience, promoting stress relief and well-being.
  8. Preventative Maintenance: Maintaining clear water often goes hand in hand with regular maintenance routines, such as cleaning filters and checking equipment. This helps identify and address issues before they become major problems, reducing the risk of costly repairs.
  9. Water Conservation: You may not need to drain and refill your hot tub as frequently. This conserves water and reduces the environmental impact of hot tub ownership.
  10. Legal and Health Regulations: In some regions, there are regulations and health codes that require hot tub owners to maintain clear and sanitary water. Failure to do so could result in fines or penalties.

Clear hot tub water is essential for safety, water quality, and overall enjoyment. Regular maintenance and proper water chemistry are key to achieving and maintaining clear water in your hot tub.

Best Ways to Keep Your Hot Tub Water Clear?

Keeping your hot tub water clear is essential for a safe and enjoyable experience. Here are some steps to help you maintain clear hot tub water:

Balanced Water Chemistry

  • Test your hot tub water regularly using a test kit to ensure the pH, alkalinity, and sanitizer levels are within the recommended range.
  • You can adjust pH levels to the recommended range of 7.2 to 7.8. High pH can make water cloudy, while low pH can corrode equipment.
  • Maintain the total alkalinity within the range of 80-120 ppm (parts per million).
  • Keep sanitizer levels (chlorine or bromine) within the recommended range to kill bacteria and algae.


  • You can use a chlorine or bromine sanitizer to kill bacteria and algae. Follow the manufacturer’s instructions for the appropriate sanitizer levels.
  • Also, consider using a mineral sanitizer or ozonator to reduce the amount of traditional sanitizer needed.

Shocking the Water

  • Shock the water on a regular basis (usually weekly or after heavy use) to break down contaminants and maintain water clarity.
  • Non-chlorine shock or chlorine shock can be used, depending on your preference and water chemistry.


  • You should always ensure that your hot tub’s filtration system is clean and in good working condition.
  • Clean or replace the filter cartridges regularly according to the manufacturer’s recommendations.

Water Circulation

  • Run the hot tub’s circulation system for several hours each day to help filter the water and evenly distribute chemicals.

Cover Maintenance

  • Keep the tub covered when not in use to prevent debris, leaves, and contaminants from entering the water.
  • Clean the cover regularly to prevent it from introducing contaminants into the water.

Regular Cleaning

  • Clean your hot tub’s interior surfaces, including the waterline, with a non-abrasive cleaner as needed to remove oils, lotions, and other residues.
  • You can vacuum the bottom of the hot tub to remove debris that may have settled.

Drain and Refill

  • You should periodically drain and refill the hot tub, typically every 3-4 months, to remove accumulated dissolved solids that can affect water quality.

Preventative Measures

  • Shower before using the hot tub to remove oils, lotions, and other contaminants from your skin.
  • Encourage your bathers to avoid using soaps or detergents before entering the hot tub.
  • Use hot tub accessories like floating oil absorbers to help control excess oils in the water.

Professional Maintenance

  • Consider having a professional service your hot tub regularly to ensure all components are functioning correctly and to address any potential issues.

You can keep your hot tub water clear, safe, and enjoyable for you and your guests. Always consult your hot tub manufacturer’s guidelines and use products recommended for your specific hot tub model and water conditions.
