Causes of Cloudy Water

Before diving into solutions, it’s crucial to understand the common reasons behind cloudy hot tub water. The primary culprits include:

1. Poor Filtration

Inadequate filtration can lead to the accumulation of debris and contaminants in the water, resulting in cloudiness.

2. Unbalanced pH Levels

Imbalanced pH levels can cause scale buildup and algae growth, leading to cloudy water.

3. High Total Dissolved Solids (TDS)

Accumulation of minerals and other dissolved solids over time can contribute to cloudy water.

4. Bacteria and Organic Matter

The presence of bacteria, oils, lotions, and other organic matter can cloud the water if not properly treated.

Cleaning Agents to Use

Aside from enzyme cleaner for cat and dog urine, there is an enzyme cleaner for hot tubs too! When it comes to selecting cleaning agents for your hot tub, opting for DIY enzyme-based cleaners can be a cost-effective and eco-friendly option. Moreover, these cleaners harness the power of natural enzymes to break down organic contaminants and maintain water clarity. Here’s how you can make your own DIY enzyme-based cleaner for hot tubs:

DIY Enzyme-Based Cleaner Recipe

Here is a DIY enzyme-based cleaner to make your hot tub water clean:


  • 1 cup citrus peels (lemon, orange, or lime)
  • 1 tablespoon brown sugar or molasses
  • 1-liter plastic bottle
  • Water


  1. Collect citrus peels from lemons, oranges, or limes. Furthermore, avoid using peels that have been treated with pesticides.
  2. Place the citrus peels in the plastic bottle.
  3. Add the brown sugar or molasses to the bottle. Furthermore, this will provide food for the enzymes to thrive.
  4. Fill the bottle with water, leaving some space at the top.
  5. Screw the cap onto the bottle and shake well to mix the ingredients.
  6. Label the bottle with the date and contents.
  7. Store the bottle in a warm, dark place for about 2-3 months, allowing the enzymes to ferment and create the cleaner.
  8. After the fermentation period, strain the liquid to remove any solid residue.
  9. Dilute the enzyme cleaner with water (1 part cleaner to 10 parts water) before adding it to your hot tub.

Steps on How to Make Hot Tub Water Clear

Here are some steps on how to make your hot tub water clear:

1. Regular Water Testing

Maintaining proper water chemistry is essential for clear hot tub water. Use a reliable water testing kit to monitor pH, alkalinity, and sanitizer levels regularly. Aim for pH levels between 7.2 and 7.8, alkalinity between 80 and 120 ppm (parts per million), and appropriate sanitizer levels to ensure water clarity and safety.

2. Maintain Proper Filtration

Clean and properly functioning filters are crucial for removing debris and contaminants from the water. Moreover, check your hot tub’s filtration system regularly and clean or replace filters as needed. Additionally, ensure adequate circulation to prevent stagnant water, which can contribute to cloudiness.

3. Shock Treatment

Regular shock treatments help oxidize organic contaminants and eliminate bacteria in the water. Furthermore, use a non-chlorine shock or a chlorine-based shock, depending on your preferred sanitizer. Follow manufacturer instructions carefully and shock your hot tub weekly, or more frequently during heavy usage or after parties.

4. Clarifiers and Flocculants

Consider using clarifiers or flocculants to assist in removing tiny particles suspended in the water. Moreover, clarifiers work by binding particles together, making them easier for the filter to trap, while flocculants cause particles to clump together and settle to the bottom for removal. Furthermore, use these products as directed and ensure proper filtration afterward.

5. Drain and Refill

If other methods fail to clear the water, it may be necessary to drain and refill your hot tub. Over time, high TDS and accumulated contaminants can become too difficult to manage, leading to persistent cloudiness. Moreover, completely draining the hot tub and refilling it with fresh water can provide a clean slate and restore water clarity.

Regular Maintenance Tips

Here are some regular maintenance tips for your hot tub:

1. Check and adjust water chemistry regularly

  • Test the pH, alkalinity, and sanitizer levels weekly using a reliable water testing kit.
  • Adjust pH levels to maintain a range between 7.2 and 7.8, and alkalinity between 80 and 120 ppm.
  • Ensure sanitizer levels (chlorine or bromine) are within recommended ranges for optimal disinfection.

2. Clean the hot tub filter regularly

  • Remove and rinse the filter cartridge every 1-2 weeks to remove debris and contaminants.
  • Deep clean the filter monthly by soaking it in a filter cleaner solution or diluted vinegar to remove built-up residue.

3. Shock treat the water weekly

  • Shock the hot tub water with a non-chlorine or chlorine-based shock treatment once a week, or more frequently during heavy usage or after parties.
  • Follow manufacturer instructions for dosage and application to ensure effective oxidation of organic contaminants.

4. Scrub and vacuum the interior surface

  • Clean the interior surface of the hot tub weekly using a non-abrasive sponge or cloth and a mild spa surface cleaner.
  • Vacuum the bottom of the hot tub to remove any debris or sediment that may have accumulated.

5. Inspect and maintain equipment

  • Regularly inspect the hot tub equipment, including pumps, heaters, and jets, for signs of wear or damage.
  • Ensure all components are functioning properly and address any issues promptly to prevent further damage.

6. Monitor water level and temperature

  • Keep the hot tub water level within the recommended range to ensure proper circulation and filtration.
  • Maintain the water temperature at a comfortable level for users while considering energy efficiency and safety.

7. Cover the hot tub when not in use

  • Use a fitted cover to prevent debris, leaves, and insects from entering the hot tub when it’s not in use.
  • Covering the hot tub also helps retain heat and reduce evaporation, resulting in lower energy costs.

8. Drain and refill the hot tub periodically

  • Completely drain and refill the hot tub every 3-4 months to remove accumulated minerals, dissolved solids, and contaminants.
  • Thoroughly clean the hot tub shell and components during the draining process to maintain water quality and prolong equipment lifespan.

Achieving clear hot tub water requires a combination of proper maintenance, regular testing, and timely treatment. By following the steps outlined in this guide and staying proactive with your hot tub cleaning routine, you can enjoy pristine water quality and a truly refreshing hot tub experience.
