Why Is My Pool Water Cloudy & How Can I Fix It? 


A swimming pool is a great addition to any home or commercial space but they also come along with a lot of hard work. As much as you might love a cannonball, you don’t want to be jumping into murky or green water. If you are noticing that your pool water is cloudy and you can’t figure out why, just call a local Puddle Pro! 

When pool water starts to go cloudy it is a sure sign that something isn’t right but figuring out exactly what that is, is easier said than done. Cloudy water is caused by an imbalance in pH levels. More than just looking awful, cloudy water means bacteria could be present inside water. Dipping a toe into dirty water doesn’t seem like that big of a deal — we swim in lakes all the time, right? — but it could present serious health risks. 

Cloudy Pool Water: A Risk to Your Health and Your Swimming Pool 

No one wants to step foot into cloudy pool water but if you aren’t much of a swimmer or it’s the off-season, balancing water chemistry isn’t usually a top priority. It’s easy to throw on a pool cover and forget to deal with the problem but it will only get worse over time. Before you know it clean water will go from clear and then cloudy, then teal until it end up being swampy and green. 

Cloudiness is caused by small particles in water that reflect light. Unlike bits of debris, these can’t be skimmed out or sucked up by a pool vacuum. These particles can be introduced into water in any number of ways including surrounding environments, swimmers and can even be left behind on the tail end of chemical lifespan. 

Chemical treatments and sanitizers will attack germs, bacteria and these particles. If chemical treatments are not performed regularly there is nothing left to attack these particles. Anything that reduces the efficiency of your pool chemicals is a big problem. High heats, heavy rains and high rates of usage will all impact overall pool chemistry. It is easy to stock up on test strips but just shocking the pool isn’t enough to restore balance. Instead, have an expert test the water, create a custom treatment plan that tests and balances chlorine levels, pH levels, total alkalinity and calcium. 

Stepping into cloudy water can lead to skin irritations, ear infections, eye infections and digestive issues. In short, if water isn’t clear and sanitary it can make you real sick, real quick! That is bad enough for homes but it is even worse for businesses. No one wants to swim in a cloudy pool and all it takes is one negative social media post to send potential customers running to your competitors. Let a local Puddle Pro create a customized treatment plan to maintain clean pool water. 

The Most Common Causes of Cloudy Pool Water 

At it’s core the main reason for pool water going cloudy is not having appropriate sanitizer levels in your pool water. You can throw in a shock treatment to clear away some of the cloudiness but there are likely still particles suspended in the water. A shock treatment is a quick fix but it doesn’t provide a long-term improvement. Don’t treat the symptom without tackling the cause too. 

Environmental Issues: Prolonged exposure to direct sunlight will cause water to evaporate and will eat away at sanitizers. Depending on the surrounding area of your pool, the natural environment and plant life will take a toll on sanitizers. In addition to the familiar factors like rain and heat, everything from bird droppings, dirt, pollen, leaves and natural debris will cause sanitizers to work harder, spreading themselves thin until they aren’t effective anymore. 

Chemical Levels: In the same way that too few pool chemicals open the door for cloudy water, too many chemicals can do the same thing! The balance of a swimming pool is like a game of dominoes, when one goes others are quick to follow: 

  • PH Levels: If pH levels are too high water is less acidic and causes scale to form in pools and in plumbing. Scale has a negative impact on pool filters and makes sanitizers less effective. 
  • Alkalinity Levels: Elevated alkalinity levels makes it difficult to stabilize pH levels and contributes to the formation of scale. 
  • Calcium Levels: When calcium levels are too high it creates a flaky buildup inside pools. These flakes will get into vulnerable areas and create clogs, like in the pump and filter. It doesn’t matter if you have a cartridge filter or a sand filter, this is always a problem. 
  • Too Much Shock: As we’ve said before, a shock treatment can help to provide a superficial improvement which is great for curb appeal and is the first step to getting your pool chemistry back on track but overuse can do the exact opposite. 

Filtration Systems: Cloudy water can cause havoc for internal water systems but if your filtration system is in bad shape, it will contribute to poor water condition. In order to keep things running smoothly it is important to clean the filter regularly, as well as keeping up with debris removal from the pool itself and the skimmer basket. It is also important to run your filter for a few hours a day just to keep things circulating.
