When your pool looks cloudy or appears like a giant bowl of milk, no-one desires to swim in it.
The whole family will choose to visit the beach or swim at a friend’s place until the situation is fixed.
A cloudy pool is uninviting bearing in mind it could be damaging your pool’s circulation system or even breeding bacteria and algae.
To avoid the cloudy water causing expensive damaged or exposing your loved one to serious health risks, it’s best you find out what caused the cloudy pool and look for suitable a sustainable solution.
There are different solutions to fixing a cloudy pool, but they vary depending on what caused the water to become cloudy.
In this guide, we are going to look at the causes of cloudy pool water and solutions to fix the situation.
Cloudy Pool Water Basics
If your water was clear the other day and cloudy today, several things can explain the situation.
Note it takes time for the water to turn cloudy.
However, once it’s fully cloudy, you need to act quickly to fix the situation.
Before proceeding to fix the situation, it’s best to first determine what made the water in your pool cloudy, which could be one of the following reasons.
Add sanitizer to avoid cloudy pool
When natural debris enters your pool, sanitizers attack it immediately.
However, sanitizers do not dissolve large solids, and this is why every pool has a filter system.
An incase in large solid particles that cannot be physically removed by the filter results in excessive consumption of sanitizer.
People also add solid particles to the water in your pool through sweat, urine, beauty products, and sunscreen.
This is the main reason why you should add sanitizers to your swimming pool from time to time.
Make sure you add sanitizers every time someone uses the pool.
You need to keep adding them considering that the sun evaporates hypochlorite ions into the air around your swimming pool.
As a result, you end up with less sanitizer and more dirt particles in your swimming pool.
Additionally, algae are another chlorine hogging agent.
As long as your swimming pool has an algae problem, you need to add high amounts of chlorine or bromine from time to time.
The best solution would be to fix the algae problem in your swimming pool.
If your pool has contaminants hogging chlorine, you will need to add more sanitizers.
The chemical concentrates on attacking rotten leaves floating on the surface yet risky pathogens and bacteria continue to thrive at the bottom of the swimming pool, causing your pool water to become cloudy, ugly, and dangerous to swim in.
Your pool’s circulation system can make pool water cloudy
Damaged pool circulation systems could also be a cause of contamination.
The only way to prevent this situation is by maintaining a healthy circulation system.
When everything in your pool is working correctly, and you run your clarifier pool pump for at least eight hours a day, there should be little or no debris or particles in the water.
All occurring dirt particles should be removed by the filter and sanitizers.
However, pool circulation systems tend to fail as they get old or damaged by high chemical levels.
Once your filter cannot remove dirt particles as it is supposed to, you end up with contaminated water and other water problems.
Pool water chemistry – how to raise ph in pool
Another major cause of poor water quality is water chemistry.
If water chemistry is out of balance, you are likely to face a lot of pool problems.
When your pool pH is high, it means your water is more acidic than it should be.
The acidic water forms a scale on the pool’s surface and plumbing system, which makes it difficult for your sanitizers to work.
Poorly balanced water chemistry can also lead to cloudiness, filtration problems, and bacteria growth.
Additionally, high alkalinity in your pool water also forms scale and does not helps stabilize your pool’s pH.
If you add too much calcium in your pool, this will lead to calcium hardness, a flaky build-up, clogging up the filter system, and cloudiness in the water.
Balanced pool chemistry should also avoid high chlorine levels as this could lead to skin and lung irritation.
You can also end up with a lot of chloramines which are irritating and corrosive at times.
Once you determine this is the cause of clouded water, go ahead and look for ways to clean the water in your pool.
Why is my pool cloudy? Algae Build-up
Water that is cloudy could also be an iceberg if you have an algae bloom.
Although pool algae are not as dangerous as those found in the wild, they create a hazardous swimming condition.
Additionally, no one will be willing to swim in a pool full of algae, making it vital to find a solution fast.
Algae cause debris to be suspended on your pool’s surface, making it impossible to see through it.
Swimming in such a pool is hazardous as people can drown as you cannot see when a swimmer is struggling underwater.
This makes it risky for children and pets.
The algae build-up does not allow anyone to swim.
Find ways to keep children and animals away from the pool to reduce risks.
Techniques/tips to clear cloudy pool water fast
Contaminated water is a common problem among pool owners.
However, there are a few tips you can use to prevent the situation.
In this section, we have compiled a few techniques you can use.
- Avoid adding over-diluted or concentrated chlorine.
- Maintain your pool filter system from time to time.
- Deal with any calcium hardness in the pool.
- Maintain optimum pool chemistry.
- Shock your pool from time to time.
Correcting pool cloudy common problems
Cloudy swimming pool water is a common problem that requires immediate attention.
There are various ways you can restore the water quality to its crystal clear glory in no time.
Some methods may require hard work, but you can be sure to get results by the end of it.
Pool water cloudy deep cleaning
Once you notice the water has become cloudy, start by scrubbing the bottom of your pool.
Make sure you remove large debris and dirt particles using a heavy-duty skimmer and manual vacuum.
Ensure you also brush the walls with a stiff pool brush before you use the manual vacuum.
If you notice you have an algae problem, vacuum up the visible particles.
Shock cloudy pool water
Another way to get rid of dangerous and gross crud in your pool is by shocking.
You can use a mega chlorine dose or non-chlorine shock or pool clarifier if you use other pool sanitizers.
Shocking your pool eliminates cloudiness resulting from algae or organic contaminants, among other bacteria.
If you are experiencing water that is cloudy due to algae, you may have to double or triple shock based on the type of algae.
Filter regularly to avoid cloudy pool water
You do not need to filter your pool non-stop.
Running your pool pump for eight hours per day is enough on average.
However, you will need to deep clean and replace your filter from time to time.
After shocking or using clarifiers, pool filter and circulation systems need to be run to be sure the sanitizer rinses everything.
Use your bottom drains to fix cloudy pool water
To fix cloudy pool water, you should make sure you get to the debris at the bottom of the pool.
Skimmers and vacuums fail to reach the bottom of your pool, and this is why you should take advantage of bottom drains.
By turning on your bottom drains, it sucks sediment straight to the bottom filter.
Balance your Chemistry (raise ph in pool if necessary)
To be sure you are safe, make sure you regularly test your pool for a high pH level from time to time.
Based on your pool’s pH, you should adjust chemicals accordingly until your water is balanced. This will avoid any problems with calcium hardness and help fix cloudy pools.
We highly recommend the use of chlorine stabilizer as it’s the best there is to fix cloudy pool problems.
Floc your pool to clear cloudy pool water
When pool cloudiness is not that bad, you can use pool flocculants.
Once you floc your pool, all the suspended debris sinks to the bottom of your pool, and to the filter.
From here, you can easily use a manual vacuum it, or use the right amount of chemicals to balance the water.
Once all this is done, you can go ahead and swim without worries.
Make use of pool water clarifier
Adding a water clarifier every week is one of the preventive measures you can take.
Water clarifiers do not address serious problems that cause cloudiness in your pool, but they help your pool look great by coalescing debris, making it easier for your pool filter to catch any particles.
Make use of your pool pump to clear cloudy pool water fast
Another way you can get rid of cloudy pool water is by running the pool pump as required.
You should run the pool pump throughout winter and summer for at least eight hours a day.
Make sure you regularly check whether your pool pump is in the best shape possible for the best results.
