How To Clear Cloudy Pool Water

It’s the time of year again. The sun is shining, the temperature is rising, and you can’t wait to take a dip in your pool. But when you take that first refreshing swim of the season, you notice that the water looks a little… cloudy. Before enjoying your pool, you need to figure out how to clear up that cloudy water.

Don’t worry; clearing up cloudy is easier than it may seem at first. In this article, we’ll walk you through everything you need to know about how to clear cloudy pool water. We’ll cover the most common causes of cloudy pool water and provide some tips for preventing cloudiness in the future. We’ll also give you step-by-step instructions for clearing up your pool water so you can enjoy your summer.

So, let’s get started.

What Causes Cloudy Pool Water?

The first step in clearing up your cloudy pool water is understanding what may be causing the problem in the first place. There are a few different things that could be causing your pool water to become cloudy. Let’s take a look at some of the most common causes:

1. Poor Filtration

If your pool filter is not working properly, it won’t be able to remove dirt and debris from the water effectively. There will be clog build-up within the filter, which will cause your pool water to become cloudy.

Also, the issue may be with exhausted pool filter media that needs to be replaced. If you haven’t replaced the filter media in a while, it may be time to do so.

2. Too Much Chlorine

If there is too much chlorine in your pool water, it can cause the water to become cloudy. This is because chlorine reacts with the water’s sweat, oils, and other contaminants to form chloramines. These chloramines cause the “chlorine smell” that you often associate with swimming pools.

Too much chlorine can also irritate your skin and eyes. Maintaining proper free chlorine levels in your pool is important to avoid these problems.

3. pH Imbalance

Another common cause of cloudy pool water is a pH imbalance. The ideal pH level for pool water is between 7.4 and 7.6. If the pH level is too low, it can lead to corrosion of pool surfaces and equipment. If the pH level is too high, it can cause scale build-up on surfaces and equipment.

Also, an imbalanced pH can make it difficult for chlorine to work properly. This means that your pool will be more susceptible to algae growth.

4. Algae Growth

Algae is a common cause of cloudy pool water. Algae can enter your pool through wind, rain, and even on swimmers’ clothes and skin. Once algae are in your pool, they will multiply quickly and cause the water to become cloudy.

Algae can also be harmful to swimmers. It can cause skin irritation and eye problems. In severe cases, it can even lead to respiratory problems. They’re common in outdoor pools but can also happen indoors if the environment is humid.

5. Too Much Dust or Dirt

If there is too much dust or dirt in your pool water, it will become cloudy. This is usually caused by windy conditions that blow dust and debris into the pool. You may also see this problem after a heavy rainstorm.

6. Poor Water Circulation

Another common cause of cloudy pool water is poor water circulation. If the water in your pool is not circulating properly, it will become stagnant, and cloudiness will develop. A dirty or clogged filter often causes this. Problems with the pump or plumbing can also cause it.

7. High Calcium Hardness Level

If the calcium hardness level in your pool is too high, it can cause the water to become cloudy. This is because the calcium carbonate in the water will start to precipitate out and form a chalky film on surfaces.

Also, if your pool is being used excessively, it can make the pool cloudy. This is because the increased traffic will churn up the bottom of the pool and stir up any dirt or debris that has settled there.

How To Clear Cloudy Pool Water With Pool Clarifier?

Now that you know some of the most common causes of cloudy pool water let’s talk about how you can clear it. A pool clarifier is a chemical you add to your pool water to help remove suspended particles. It works by binding the particles together so they can be more easily filtered out.

It is a great way to quickly clear up the cloudy pool water. However, it’s important to use them correctly. Here’s how it works:

1. Skim And Vacuum Your Pool First

No products found.

First things first, you’ll want to remove any large debris from the surface of the water. This will help prevent the clarifier from binding to these particles and making them more difficult to remove. Use a skimmer or a leaf net to remove leaves, bugs, and other debris from the water’s surface.

2. Test The Water And Adjust The pH Level

No products found.

Next, you’ll need to test the water to see the pH level. The ideal pH level for pool water is between 7.2 and 7.6. If your pool’s pH level is too high or too low, it can make it harder for the clarifier to work properly. You can use a pool test kit to test the pH level of your pool water.

3. Add Pool Clarifier According to Package Directions

No products found.

Once you’ve adjusted the pH level of your pool water, it’s time to add the clarifier. Follow the package directions carefully so that you add the correct amount. Most clarifiers should be added directly to the skimmer basket.

4. Run Your Filter for 12 to 24 Hours After Adding Pool Clarifier

After adding the clarifier, you’ll need to run your filter for 12 to 24 hours. This will help remove the particles that the clarifier has bound together. Also, backwash your filter according to the manufacturer’s directions.

After running your filter, you’ll want to vacuum the pool again. This will help remove any remaining particles that the clarifier has bound together.

5. Repeat as Needed Until The Water is Clear

If your pool water is still cloudy after following these steps, you may need to repeat the process. Continue to add a clarifier and vacuum the pool until the water is clear. Depending on the severity of the problem, it may take a few days or even a week to get rid of all the cloudy water.

Don’t forget to test the water regularly and adjust the pH level as needed. With a little effort, you’ll have your pool looking crystal clear in no time. If it’s still cloudy, you may need to shift to a flocculant.

How to Use Pool Flocculant?

No products found.

If you have ever wondered how to get rid of cloudy water in your pool even after using a clarifier, chances are you need to use a flocculant. Flocculants are chemical agents that clump together small particles in water, making them heavier so they can sink to the bottom of the pool, where they can be vacuumed.

The manual effort of vacuuming these particles can be quite tedious, and it may take several rounds of vacuuming to get rid of all the dirt finally. This is where using a flocculant can save you a lot of time and effort.

When used correctly, flocculants can quickly clear up your pool water within 24 hours, leaving you with fresh, sparkling water ready for a dip!

Several types of flocculants are on the market, but polymeric aluminum sulfate is the most common and effective type used for pools. You can purchase flocculant at most pool supply stores or online.

The steps to use them effectively include:

1. Balance Your pH and Alkalinity Levels

First, you need to ensure that your pH and alkalinity levels are balanced before adding a flocculant. If these levels are off, it can cause the flocculant to be less effective or even cause problems with your pool equipment.

You can test your pH and alkalinity levels with a pool test kit, which you can purchase at most pool supply stores or online.

2. Test the Water for Metals

It’s also important to test your pool water for metals such as iron and copper before using a flocculant. This is because some flocculants can cause staining if there are high levels of metals present in the water.

You can test for metals with a pool test kit or by sending a sample of your pool water to a laboratory.

3. Calculate the Amount of Flocculant You Need

Once you know that your pH and alkalinity levels are balanced and there are no metals in your pool water, you can calculate the amount of flocculant you need to add.

The amount of flocculant you need will depend on the size of your pool and the level of turbidity (cloudiness) in your water. You can use a flocculant calculator to determine the amount of flocculant you need, or you can follow the directions on the product label.

4. Add the Flocculant to Your Pool

After calculating the amount of flocculant you need, it’s time to add it to your pool. The best way to add a flocculant is to pour it into a clean bucket and then slowly walk around the perimeter of your pool, pouring it in as you go.

Alternatively, you can add the flocculant directly to your skimmer basket or automatic pool cleaner.

5. Vacuum the Bottom of Your Pool

Once you have added the flocculant, you will need to vacuum the bottom of your pool to remove all the dirt and debris that has been clumped together.

You can vacuum your pool with an automatic pool cleaner or a manual vacuum. It’s important to vacuum slowly and methodically to ensure you pick up all the dirt.

It may take several rounds of vacuuming to finally get rid of all the dirt, but once you’re finished, you should have clean and sparkling water ready for a dip.
