Few pool problems are as frustrating as walking outside and thinking, “Why does my pool look like this?” If you’ve ever said “my pool water is cloudy”, you’re not alone. Cloudy water is one of the most common pool issues homeowners face, and it’s usually a sign that something in the system is out of balance.
The good news is that cloudy pool water is almost always fixable. The key is understanding what causes it and choosing the right solution before the problem gets worse. At Anomaly Pool Services, we help pool owners across North Texas restore water clarity through professional cleaning, testing, and chemical balancing.
This guide breaks down the causes of cloudy swimming pool water, how to fix it fast, and when it’s time to call a professional.
Before you can clear cloudy water, you need to know what’s behind it. There isn’t just one cause, cloudiness usually comes from a combination of chemistry, filtration, and circulation issues.
Understanding what causes cloudy pool water helps you fix the issue faster and prevent it from returning.
Yes, low chlorine is one of the top causes of cloudy pool water. Chlorine is responsible for killing bacteria, breaking down contaminants, and preventing algae. When levels drop too low, organic debris stays suspended in the water.
Signs low chlorine is the issue:
A pool water testing service can quickly confirm if chlorine is the problem and recommend the right correction.
Absolutely. Many pool owners are surprised to learn that high pH can cause cloudy pool water even when chlorine levels look fine.
When pH rises too high:
Balanced chemistry is essential. This is where pool chemical services & balancing from professionals can save time and prevent trial-and-error fixes.
Yes. High calcium hardness can make pool water cloudy, especially in areas with hard water.
When calcium levels are too high:
High calcium often goes hand-in-hand with total dissolved solids in pool water, which we’ll cover next.
Total dissolved solids in pool water refers to everything dissolved in the water, minerals, salts, metals, and leftover chemicals.
High TDS can:
When TDS gets too high, partial draining and refilling may be the only solution. A professional pool water testing service can measure TDS accurately and guide the next step.
Yes, and this is one of the most overlooked issues. A dirty pool filter can absolutely cause cloudy water.
If your filter is clogged:
Regular filter cleaning and proper run time are essential. If your pool stays cloudy despite balanced chemistry, the filter is often the culprit.
Even with clean filters and good chemistry, swimming pool circulation problems can prevent water from clearing.
Poor circulation allows:
Running the pump long enough and ensuring returns are positioned correctly is key to clear water.
Cloudy pool water after rain is extremely common. Rain introduces:
After heavy rain, pools often need extra filtration time and chemical adjustments. Ignoring post-rain cloudiness can quickly lead to algae growth.
Yes. Algae is one of the most common reasons a pool turns cloudy.
Early-stage algae often appears as:
As algae spreads, the pool can turn fully green.
If you’re asking “why is my pool water green and cloudy?”, algae is almost always involved.
Causes include:
At this stage, brushing and shocking alone may not be enough. Swimming pool algae removal service or green pool cleanup services can restore water faster and more safely.
Yes, it can be. Many people panic when they notice their pool cloudy after shock, but this is often temporary.
Shocking kills algae and bacteria, turning them into tiny particles that cloud the water until the filter removes them.
You may notice:
Typically 24-72 hours, depending on:
Running the filter continuously and cleaning it frequently speeds up clearing.
