How to Clear Up a Cloudy Swimming Pool: Simple Steps for Crystal Clear Waters
July 27/2023

A cloudy swimming pool can be a frustrating sight, especially when you're eager to take a refreshing dip on a hot day. Cloudiness in pool water is often caused by various factors, such as improper water balance, debris accumulation, algae growth, or inadequate filtration. However, fear not! Clearing up a cloudy swimming pool is a manageable task that can be accomplished by following a few straightforward steps. In this blog, we will guide you through the process of restoring your pool to its sparkling, crystal-clear condition.

Step 1: Test and Balance the Water Chemistry
The first and most crucial step to clear up a cloudy pool is to test the water chemistry. Use a reliable pool water testing kit to measure the pH, chlorine levels, alkalinity, and calcium hardness. Imbalanced water chemistry can lead to cloudiness and create an environment conducive to algae growth.

To adjust the water chemistry, follow these general guidelines:

pH: Maintain a pH level between 7.4 and 7.6. Use pH increasers or decreasers as needed.
Chlorine: Keep the chlorine level between 1.0 and 3.0 parts per million (ppm) to prevent bacteria and algae from thriving.
Alkalinity: The recommended range is 80 to 120 ppm. Use alkalinity increasers or decreasers to achieve the ideal balance.
Calcium Hardness: Aim for a calcium hardness level between 150 and 250 ppm. Use calcium hardness increasers if the level is too low.
Stabilizer (Cyanuric Acid): Test stabilizer levels to maintain a level of 30 to 70 ppm to protect the chlorine from UV rays.

Step 2: Shock the Pool
Once the water chemistry is balanced, shock the pool with a high dose of chlorine. Shocking the pool helps to eliminate bacteria, algae, and other organic contaminants that may be contributing to the cloudiness. Follow the manufacturer's instructions on the pool shock product for proper dosing, based on your pool's size and current condition.

Step 3: Clean the Pool
Thoroughly clean your pool to remove debris, leaves, and any other visible contaminants. Use a skimmer net to scoop out leaves and larger debris from the water's surface. Additionally, brush the pool walls, floor, and corners to dislodge any dirt or algae clinging to them. This step ensures that the pool's filtration system can work efficiently.

Step 4: Check and Clean the Filter
A clogged or dirty filter can contribute to cloudy water. Inspect your pool's filter and clean or replace it if necessary. There are three common types of filters: sand, cartridge, and diatomaceous earth (DE) filters. Follow the manufacturer's instructions on cleaning or backwashing your specific filter type.

Step 5: Run the Pump and Filter
To circulate the pool water effectively, ensure that the pump and filter are running for an adequate amount of time each day. During cloudy water issues, consider running the filtration system for longer periods than usual until the water clears up. It's probably best to run it 24 hours a day. Continuous circulation will help the filter catch and remove smaller particles that cause cloudiness.

Step 6: Use a Pool Clarifier
If the water remains cloudy even after completing the previous steps, you can consider using a pool clarifier. A pool clarifier works by gathering fine particles together, making them easier for the filter to trap. Follow the product instructions for proper dosage and application.


Step 7: Preventative Maintenance
Once your pool is clear and inviting again, it's crucial to maintain proper water chemistry, regular cleaning, and filtration to prevent future cloudiness and water quality issues. Test the water regularly, clean the pool as needed, and keep the filter in optimal condition.


Clearing up a cloudy swimming pool requires a systematic approach, starting with testing and balancing the water chemistry. Regular maintenance, proper filtration, and timely cleaning are key to preventing cloudy water in the future. By following these simple steps, you can ensure your pool remains a pristine oasis for enjoyment and relaxation all summer long. Remember, a little effort in maintaining your pool will lead to crystal-clear waters and happy swimmers!
