How to Fix a Cloudy Pool: Expert Tips for Restoring Water Clarity

A cloudy pool can be frustrating, whether you're preparing for a pool party, just want to enjoy a relaxing swim, or are trying to maintain a safe and clean environment for your family. Cloudiness is often a sign that something is wrong with the pool water’s chemistry, and if left untreated, it can lead to further problems, including algae growth and bacterial issues.

In this article, we’ll guide you through the steps to fix a cloudy pool and restore it to its crystal-clear glory, with advice from the experts at Beach Bros Pools.

What Causes a Cloudy Pool?

Before diving into how to fix a cloudy pool, it’s important to understand the causes. Cloudiness typically occurs due to one or more of the following reasons:

1. Imbalanced Water Chemistry – High levels of chlorine or improper pH balance can make the water cloudy.

2. Inadequate Filtration – A malfunctioning filter or dirty filter media can cause particles to remain in the water.

3. High Levels of Total Dissolved Solids (TDS) – Over time, accumulated chemicals can make the water cloudy.

4. Algae Blooms – Algae can thrive in poorly maintained pools, leading to green or cloudy water.

5. Debris and Contaminants – Leaves, dirt, oils, and lotions can make your pool water murky if not regularly cleaned.

Step-by-Step Guide: How to Fix a Cloudy Pool

1. Test and Balance Your Pool Water Chemistry

The first step to clear pool water is checking your pool’s chemical balance. You can buy a pool water testing kit or take a sample to a local pool store for a professional test. Pay attention to:

  • pH Level: The ideal pH range for pool water is 7.2 to 7.8. If the pH is too high or low, it can affect chlorine effectiveness and cause cloudiness.

  • Free Chlorine: Ensure the chlorine level is between 1-3 ppm (parts per million). Too little chlorine can allow bacteria and algae to grow, while too much can lead to poor water quality.

  • Alkalinity: Ideal alkalinity levels are between 80-120 ppm. Low alkalinity can lead to pH instability, while high alkalinity can cause cloudiness.

  • Hardness: If the hardness is too high, it can cause scale buildup and cloudy water. Aim for a range of 250-500 ppm.

Adjust the chemicals accordingly, using pool-safe chemicals, and wait 24 hours before checking again.

2. Clean the Pool Filter

A clogged or dirty filter can prevent proper filtration, which leads to particles and debris floating in your pool water. Clean your filter thoroughly to ensure it’s working effectively.

  • Cartridge filters: Rinse thoroughly with a hose and soak in filter cleaner if needed.

  • Sand filters: Backwash to clear out debris and sediment. You may also need to replace the sand every few years.

  • DE filters: Clean the filter grids and add new DE powder if necessary.

Ensure that the filter is operating correctly by running it for several hours after cleaning. For our guide on filter cleaning, use this link: https://www.beachbrospools.com/how-to-clean-pool-filter

3. Shock the Pool

If the water is still cloudy after adjusting the chemicals, shocking the pool is an effective way to clear up stubborn cloudiness. Shocking involves adding a large dose of chlorine to rapidly kill bacteria and algae.

  • Chlorine shock: Follow the manufacturer’s instructions to apply the right amount of shock for your pool size.

  • Non-chlorine shock: This type is often used for pools that are sensitive to high chlorine levels, though it’s not as effective in clearing cloudy water caused by high bacteria levels.

For best results, run your pool’s filtration system for 24-48 hours after shocking.

4. Use a Pool Clarifier

A pool clarifier is a chemical that helps to bind together small particles that are too tiny to be filtered out. When these particles clump together, your filter is more likely to capture them, and your pool water will clear up faster.

To use a clarifier:

  • Add the recommended amount based on your pool size.

  • Turn on the filter and let it run for at least 8 hours, or overnight if possible.

Keep in mind that clarifiers can sometimes cause cloudiness temporarily, but the result is usually clear water after filtration. Additionally, using clarifier in not recommended when using DE and Cartridge filters as it is difficult to remove from the pleats.

5. Remove Debris and Vacuum the Pool

Sometimes the cloudiness in your pool is due to debris settling on the bottom or floating in the water. Regularly remove leaves, twigs, and other debris with a skimmer. You should also vacuum your pool thoroughly to ensure that all the debris is removed.

Investing in an automatic pool cleaner can help maintain cleanliness without as much effort on your part.

6. Backwash and Replace Water if Necessary

If the water remains cloudy despite your best efforts, it may be a sign that the Total Dissolved Solids (TDS) are too high. In this case, backwashing the filter can help remove some of the dissolved solids. If necessary, you can also replace a portion of the pool water to lower the TDS and restore clarity. If you intend to drain a significant portion of your pool, it's best to use a professional.
