What Causes Cloudy Pool Water

Cloudy pool water is a condition where the water loses its transparency, becomes unattractive and is impossible to swim in

In the experience of pool users, bacteria and various microorganisms are usually the cause of cloudy water. But these are not the only reasons for the loss of clarity, so let’s look at some more possible causes: 

  • Insufficient filtration: This process is very important in cleaning the water in the pool. If the filter is not working properly, it can cause it to stop removing small particles of dirt and dust, in turn leading to cloudy water. 
  • Low chlorine content: This substance is used to eliminate bacteria and pathogens. If the chlorine level is too low, hazardous chemicals might form, resulting in cloudy water.
  • Entry of extraneous microorganisms: If the dust, dirt, leaves, or tanning oil gets into your pool water, it all causes decomposition in the water and the appearance of bacteria. The bacteria, in turn, make the water become cloudy. 
  • Improper use of chemicals: Using the wrong components for water treatment, can lead to cloudy water. For example, if you add a few agents, it will cause insufficient water purification, and if on the contrary too much β€” chemical disequilibrium.
  • Many people: When many users are in the hot tub at the same time, this leads to a heavy load and increased contamination of the water, which causes clouding. 
  • Damage to cleaning filters and other components: If certain technical components are broken or damaged, they will not fully perform their functions, resulting in poor water purification and therefore cloudiness. 

What Are the Dangers Of Swimming In Cloudy Water In The Pool?

As experts, we do not recommend swimming in a pool with cloudy water. You should understand that such bathing carries certain health risks for you and others. 

Let’s take a closer look at these causes and why they occur:

🧹 Contamination: Cloudy water contains sand, residual chemicals, and foreign microorganisms. All of these can cause allergic reactions, irritation, and infections on your skin. 

πŸ‘€ Poor visibility: Cloudy water limits visibility underwater, which in turn poses great risks to swimmers in the pool. When visibility is poor, it becomes more difficult to see obstacles and other objects (such as filters, and steps). It can lead to injuries. 

🦠 Spreading bacteria and disease: Cloudy water is a spreader of harmful microorganisms and infections. Such water can carry E. coli and skin diseases.

⬇️ Falling and slipping: Cloudy water causes sludge and silt to build up on the bottom of the pool. It can cause a person to slip, fall, and be injured.

🀧 Occurrence of an allergic reaction: Cloudy water contains dust, sand, dirt, mold, and other irritants. People who are prone to allergies after swimming in such water may experience symptoms such as itching, irritation, reddening of the skin, and problems with breathing.

All of these points are dangerous to your health, so it is better not to risks and not swim in such water. 

How To Clear Cloudy Pool Water: The Best Tools

How to Clear Cloudy Pool Water: The Best Tools

If your pool water is cloudy, do not worry too early, you can try to clean it at home by following simple rules:

  1. Pay attention to the cleanliness and condition of your water filter. More often than not, filtration is the key to cleaning, so you need to get the filter out and make sure it is unclogged and working properly. If you notice that it is dirty, take it out, carefully wash and clean it, then put it back in and check that it works.
  1. Turn on the water circulation system. This system is responsible for moving water from the pool to the filter and back. It plays an important role in keeping the water clean and chemically balanced by removing impurities and ensuring the proper distribution of chemicals. So you need to make sure that this system works. If not, turn it on and check the condition of the water after this process.
  1. Check the pH and chlorine levels in your pool. An improper balance of these components can result in cloudy water. Use special test strips to check the levels of these two chemicals. If at least one or the other element is lower or higher, properly balance them. 
  1. Use simple plastic balls or green peas. These substances have special properties to collect fine particles and improve water clarity. Add a small amount of green peas to your pool and stir the water. The balls will attract and combine dirt and dust particles. It will help them settle to the bottom or clean into the filter. 
  1. Use microfiltration with a rag. Take a clean cloth (not synthetic), and put it on the end of your pool cleaner or cleaning nozzle. Then slowly go over the walls and floor of your pool. It will help remove dirt and clean out plaque and mold.

How To Clean a Cloudy Pool With Baking Soda

Baking soda (or, as it is also called, sodium bicarbonate) can be used to clean pool dirt and cloudy water. However, this ingredient is not a panacea for cleaning and maintenance, but when it is used properly, can significantly improve water quality. 

We’ve prepared a step-by-step cheat sheet for you on how to properly use baking soda to clean your pool. 

Step 1: Before using baking soda, balance the alkalinity and pH chemistry. Use special test strips to determine what level these components are at. Baking soda brings the acidity level to the right level. You should add it when the pH level of your water is below 7.2. This will help to bring the pH back to normal and clean the pool of bacteria. 

Step 2: In order to properly use baking soda, you need to determine the right amount of baking soda to add so as not to disrupt the water chemistry. Add half a cup of baking soda for every 10,000 liters of pool water. After that, stir it thoroughly so that it dissolves completely. 

Step 3: Pour the baking soda solution evenly completely over the entire surface of the pool. Use a baking soda brush to spread the baking soda evenly over the pool surface. Then allow the baking soda to settle for one hour. 

Step 4: After the baking soda has settled in the pool for an hour, turn on the filtration system and leave it for 4 to 12 hours. While filtering, you can gently pierce the dust and dirt bubbles with a pool brush. It will help the filter deal with the dirt faster and easier. 

Step 5: After the baking soda water purification process, you can retest the water to make sure all the chemicals are at the proper levels.
