How To Raise pH Level In Pool? Simple And Effective Steps


A swimming pool must always be well maintained and in the maintenance, having a balanced pool water pH is an important factor not to be ignored at any cost. The installation of hidden pools is incomplete without attaining required pH levels.

If pH is optimal, then the metal fittings inside the pool as well as the walls of the pool will remain clear. Also, enjoying swimming in a pool is possible only at the right pH level, so that you don’t have an itchy or burning skin experience (How To Setup A Fresh Water Pool). 

The optimal pH of a swimming pool must be maintained between 7.4 and 7.8. If your pool water fails this pH level test, then below are the techniques to help you raise the pH,but first let us know the exact reasons of drop in pH levels.

Causes Of Low PH?

A number of factors are responsible for low pH.

Local Water Source

The most common reason is that your source of water supplies water with low pH.

Chemical Source

Excess quantity of pH reducer is one of the cause, which you might have used earlier to control high pH levels. Sometimes we need to add chlorine tablets which are also responsible for a reduction in pH level, bringing it around 2.8. If you have been using bromine in your pool then the pH will remain at 4. Shocking is another treatment that leads to lowering of water pH.

Rain Or Ground Water Source

You may sometimes observe that after a heavy lash of rain, pH of your pool has more acidity. If flood water enters into your pool it can also reduce the pH.

Organic Source

If your water pool is surrounded by trees then the leaves, bugs or grass will be another reason of reduced pH level.

Human Source

Using a pool also contributes to the imbalance of pH due to addition of sweat, body oils, saliva, and urine. So it is always a good measure to monitor the pH some days of pool usage.

Steps To Increase PH Levels

Adding Soda Ash

Adding Soda Ash To Pool

If pH of your pool water is low, you can add sodium carbonate also called soda ash. A general rule to add Soda Ash is that you must add 2 lbs of soda ash in 10,000 gallons of water of the swimming pool each time you perform the treatment.

The soda ash must be spread in the pool surface, beginning from the deepest part of pool. At the same time the pump must be kept ON to circulate and distribute the soda Ash added in water evenly and test after an hour later for the new pH value.

Add more Soda Ash if the pH is still less. If your pool water becomes cloudy it will clear in a day.

Add Baking Soda

Adding Baking Soda To Pool

If the pool water pH still remains low despite adding soda ash, then low alkalinity may be the reason. It should be between 80 ppm and 150 ppm.

To raise it by a value of 10 ppm, add 1.4 lbs of sodium bicarbonate (baking soda) in 10,000 gallons pool water.

Check again after an hour after applying more circulation.

Aeration Of Pool

Aeration Of Pool

Aerating pool water is another useful step to raise pH. Use water jets to keep the water moving towards and around the pool surface. Carbon dioxide will be driven out in this process and raise the pH with no effect on the total alkalinity. It is a time consuming process and may take many days to complete but still the most reliable method for maintaining a stable and low pH.

Other Methods To Take Care

  • Manufacturer’s instructions must be followed. This will help in managing harmful chemicals, sodium carbonates to prevent unwanted reaction with water.
  • On a windy day add the sodium bicarbonate powder downwind to prevent its blowing back and add it by keeping the container close to the water surface.
  • Begin with 75% of your pool requirements and run the filter pump. After waiting for an hour, test for pH and add the remainder if needed. This will prevent over acidifying the pool so that you don’t have to lower down again.


The pool water pH tend to change after some time due to the factors discussed above. The best thing to do is to check the pH level regularly to do the needful whenever it falls lower than the threshold. This will keep the equipment and metal components of pool, safe from damage as well as the pool with remain stain free.

How To Setup A Fresh Water Pool

fresh water pool

Everyone in his lives, at some time, have dreamt of swimming under a waterfall or in fresh water lake.

With the help of technology, you can fulfill this dream right in the comfort and hygiene of your home and enjoy swimming in fresh water in the in-home pools.

The normal swimming pools are often treated with harsh chemicals for cleaning, which pose a serious threat to not only our skin, but also cause a variety of other serious ailments affecting the respiratory system or contracting eye-infections.

Chemical-free pool is the need for the people who care for their health and want to prevent their families from poor water conditions of a pool or spa. By taking some extra efforts and some routine maintenance, we can have a natural fresh water pool at home.

Steps To Maintain A Fresh Water Pool

  • Dust and dirt are the major deterrents to fresh water pool. Prepare a schedule for daily cleaning of this debris. Filter out leaves or any visible foreign material from the pool with the help of a net, otherwise it can lead to algae growth or cloudy water.
  • It is easier to clean the upper layer of swimming pool, but most of the sediments and contaminants remain at the bottom of the pool, un-noticed. Clean the underwater surface, behind the stairs and other nooks and corners of pool with brush, on frequent basis.
  • Another way of keeping the water fresh is to regularly circulate the water. If fresh water continuously it will ensure the overall cleanliness of your pool. The ground water drainage system is a good option to get rid of contaminants.
  • Have you ever seen moss/mosquitoes floating in ponds? The moss is a natural-cleanser for water and the same concept can be utilized in your swimming pools. Sphagnum moss is easily available and can be used in pools to have a clean pool and the fresh feeling of pond water.
  • The bacterial growth can be inhibited by electric shock treatment. The electric cleaning system creates ions like copper, iron and silver in water, which changes the composition of water and restricts any bacterial breeding.
  • A new way has been invented to eliminate the algae, in the form of ultrasonic waves. These ultrasonic waves which cannot be heard by humans are quite effective in destroying algae of any nature without creating any negative effect on water conditions.
  • There are other ready-made chemical free sanitizing systems available in the market. Installed by professionals, these are gaining popularity due to its effectiveness in creating environment friendly pools.

Reasons To Avoid Salt Water Pools

Salt water in swimming pools is not only hazardous to your health, but also damages the pool surface and landscape.

  • Salt water in the pool can damage the plants and lawns, when gets in contact.
  • The filtration systems or other drainage equipment installed in the pool, gets deteriorated early with harmful salty water.
  • Maintaining a chemical-pool is a costly affair. The chemicals used and the cost involved in replacing damaged equipment is a burden to pocket.
  • Swimming costumes also get affected by the chemicals used in water.

Benefits Of Having Fresh Water Pool

There are many environmental and health benefits of fresh water pools. The environment friendly pools are very easy to maintain.

The expenses to upkeep and maintain pools involves electricity charges, chemicals used and the cost of replacing the equipment affected by chemicals.

Since fresh water pools are chemical-free, the overall life of equipment, glass fencing, internal walls, stairs and even surroundings is enhanced, protecting them from discoloring and rust.

People who are suffering from asthma or eczema, often have to suppress their desire of swimming.

But with the possibility of having fresh water pools at home, they can also enjoy this leisure without any worry about their skin condition. Another benefit is that the recycled water can be used in the lawn and garden for watering plants.


Fresh water pools are the chlorine free pools, are the choice of millions of people now. It is regarded as a healthier alternative to chemically treated pools.

Rather than thinking of how to buy fresh water pools, you can convert your chlorine water pool to fresh water pool by following certain steps.There are certain steps which are to be followed to manage clean and fresh water.

Once you are successful in creating a fresh water pool, it will help you to reduce your operational and maintenance costs along with un-matched health and environmental benefits.

How To Fix and Clear Cloudy Pool Water

Cloudy Pool Water

You have a luxurious and expensive pool at home and one day you are enjoying swimming or in a sparkling clear water and the next day you see a transparent pool water has turned into muddy looking cloudy water, much to your annoyance.

Swimming in cloudy water is prohibited since it can cause swollen eye and many kinds of skin diseases. Once the pool gets cloudy, it is not an easy job to clean it.

There are many factors that contribute to the cloudiness of pools; even the well maintained pools face the wrath of this contamination.

How The Pool Gets Cloudy

Pool Chemicals

Certain chemicals are necessary for upkeep of pools but uncontrolled dosages can disturb the balance needed in pool water. Following levels of chemicals can make the pool cloudy

All the above factors create extra particles and contamination that make the pool-water look cloudy.

Filtration Problems

The major reason of pool growing cloudy is either mal-functioning or non-functioning of filters, which are responsible for cleaning of pools. It is therefore necessary to keep an eye on filters installed in pools. The filters must work for at least 8 hours in a day to achieve the optimal conditions of pool water. Remember, stagnant water for longer period of times means higher chances of water getting cloudy.

The Atmosphere

The surrounding environment is equally important in affecting the condition of pool-water. Too much dust, non-fencing of pools, presence of algae, invasion by Mosquitoes, birds weather conditions and behavior of pool users can lead to cloudy water.

How To Get Rid Of Cloudy Water

Once you know the reason, it is easy to diagnose the problem. So first and foremost step is to clean the cloudiness is to know the most apparent reason for cloudiness. Easiest way is to get one test-kit which helps in knowing the chemical proportions present in pool water. If you find any discrepancy in the balance of chemicals, you can correct it by taking appropriate action and which might be the reason behind the cloudiness.

Use A Pool Clarifier

The filters installed in pools are effective to collect and remove only large particles but smaller particles are often left behind in the pool which contributes to pool cloudiness. Here the role of pool clarifier is very important, whose main objective is to collect or in more scientific terms coagulate the tiny particles, bind them to form larger particles, which can be then filtered easily.

Use Pool Floccunant

Floc is another, very effective method to clear the pool overnight (another pool maintenance tip). You have arranged a pool party next day but suddenly you observe the pool is cloudy and not in a condition for swimming, there is no point losing the hope and with some extra efforts, the pool can be de-clouded by using this miracle chemical called floccunant.

Floccunant works by collecting all the particles and contaminants, responsible for cloudy pool and sends them to the bottom of the pool. Remember these particles will not be able to get filtered out by filters rather you have to look for some alternative method to eliminate the contaminants from the floor.

Bottom Drainage Systems

Any filter system installed in pool is effective only to clean the pool at the top layer of pool only and is not able to collect and filter the particles from the bottom of pool. Following ways can help you clear the pool at the bottom as well.

  • The pool has to be stirred regularly either by using pool-brush or by other electrical stirrers, the idea is to push the cloudy articles to the top of pool and not let them settle down.
  • In ground pools and hidden water pools have the option of getting drainage system installed at bottom of the pool. Turning on the drain filters at the bottom and pulling the water off the circulation will clear the way for clean water at top.
  • But what if you have an above ground pool? You cannot install bottom-drainage systems but yes, you can pull the water from bottom to the top by installing a vacuum cleaner at the bottom which will circulate the water from bottom to the top

Important Faqs (Frequently Asked Questions) On Cloudy Pool

Why Is My Pool Still Cloudy/Murky After Clarifier

A pool clarifier collects together all tiny particles from the pool and this helps the filter to efficiently remove them, thus giving you clean water.

However, before using a clarifier, you need to read all the directions carefully.

  • If the treatment goes wrong, or if you over treat you pool with clarifier, your problem gets worse. If the pool water has not cleared in your first dose of clarifier treatment, use a second dose or even stronger clarifier chemical and continue with your filtration system.
  • You need to understand that too much concentration of clarifier chemical will actually work against the clarifying process. Instead of attracting all the tiny particles to come together, they will repel, thus worsening the situation. Also, multiple and over treatment of your pool with clarifier can cause skin irritation to the swimmers.
  • Read the label instructions carefully and ensure that you do not treat your pool with clarifier for more than two times in a week.
  • If you are unable to clear your pool even after multiple attempts, there might be issues with filtration as bad filters generally result in cloudy pool waters. If you are unable to detect real reason behind pool water, you need to better consult a pool cleaning professional who can get the work successfully done for you. The pool cleaning professionals are specially trained to detect the unseen problems behind your cloudy pool. There might be some cleaning hardware that is malfunctioning.

What Does Shocking The Pool Mean

  • Shocking means to super chlorinate the pool by adding 10 times the normal amount of chlorine or any other chemical sanitizer. This raises the chlorine levels in the pool drastically for a short period. During this time, when the concentration level reaches a point called as ‘breakpoint chlorination’, the pool achieves shock status during which something of a shock rips through the water that slashes and burns everything in its path. The free chlorine oxidizes all the organic matter present in its path. This way, the pool water becomes safe and clean. Experts recommend shocking your pool at least once a week. You can do so by making use of any form of chlorine, but you need to ensure that you are using correct dosage.
  • Some people prefer to use slow dissolving chlorine tablets. This option might work efficiently to slowly release chlorine into your pool waters, but will eventually fail to achieve concentrated chlorine levels in the pool, thus resulting in failure of shocking process.
  • You can also shock your pool with non-chlorine method where you usually make use of potassium monopersulphate. This method is preferred when you want to resume swimming within 15 minutes of treatment whereas chlorine shock treatment needs you to wait for sufficient time to allow the chlorine levels to return to normal stage. Hence, if you prefer a chlorine shock treatment over non-chlorine shock treatment, you can plan it during evenings by allowing the pool pump and filter to run overnight.

Will Low Ph Cause Cloudy Pool Water

  • If your pool is full of chemicals that exceed the normal recommended limits, the water might turn out to be cloudy. The chemicals include in your pool high calcium hardness, high levels of chlorine or other sanitizers, high alkalinity or high pH.
  • The pH levels in your pool water decide how every chemical in your pool should function.
  • When pH levels are too high than the recommended limits, chlorine in your pool turns out to be ineffective. This way, the intention behind adding chlorine to your pool becomes waste.
  • Ensure that the pH levels in your pool are within the range of 7.4 to 7.8 ppm. Try to reach 7.6ppm as the target pH level.
  • If your pH level has increased high, you can reduce the concentration by making use of ‘pH Reducer’, referred to as ‘pH Minus’ such as sulfuric acid or muriatic acid.
  • If your pH level is below 7.0ppm then, it means your pool has too low pH. Low levels of pH will not only turn your pool cloudy, but also allows harmful bacteria like algae to thrive into your pool. This causes the pool to turn green. You can increase the pH level concentration in your pool by making use of ‘pH Increaser’, referred to as ‘pH Plus’ such as soda ash.
  • Lastly, take care that the alkalinity of your pool is within the range of 80 – 120 ppm so that pH levels do not rise to cause calcium scaling.

Is Your Pool Still Cloudy After Shocking

If your pool appears cloudy even after shocking; there might be issues with the filters. You must know that there might be several reasons to turn the pool waters cloudy. Hence, shocking alone will not clear up your cloudy pool.

  • Try checking if there are any filtration issues. If your filters are not working properly then, all your pain to shock your pool will land in vain.
  • If you are making use of a good working sand filter, it might take several hours, even up to a week or more to clear your pool completely.
  • You need to ensure that your cartridge filter is working well and you need to clean it every day until your pool water turns clear from cloudy condition. You can only do that much of maintenance with cartridge filters.
  • If you are making use of a good DE filter, your pool water will generally not turn cloudy if the pump runs on a long enough cycle. If your pool uses DE filter but your pool water is still cloudy, then one of the following reasons could be the reasons for foggy water and you need to repair the filter accordingly.
  1. The filter is not backwashed
  2. DE is not fresh
  3. The filter is defective
  4. The filter is not functioning properly
  5. You might have torn filter grids
  6. There might be a broken manifold
  7. DE powder might not be shooting back into the pool when you add it

How To Clear Up Cloudy Pool Water Quick & Fast

If you want to clear up you cloudy pool water to quickly appear clean, you can follow one or more of the methods mentioned below:

  • Check if the filtration process is happening correctly. Check each and every type of filter you have used in your pool maintenance system.
  1. Check if DE filter is fresh or not
  2. Check if your filter grids are torn
  3. Install a new DE filter if you encounter a defective one
  4. Backwash your DE filter
  5. Clean your cartridge filter
  • Check and find a solution if you encounter with improper pH balance in your pool.
  1. If the pH balance is above the recommended level, mostly above 7.6 ppm, reduce it by making use of ‘pH Plus’ or ‘pH Increaser’
  2. If the pH balance is below the recommended level, mostly below 7.4 ppm, increase it by making use of ‘pH Minus’ or ‘pH Reducer’
  • Make use of pool floc. This chemical clears your cloudy pool very fast by transforming it to crystal clear overnight. It is different from clarifier in a way that instead of collecting the tiny particles together and assisting the filter, the pool flocculants collect the tiny dirt particles at the bottom of the pool. Then you need to vacuum the dirty water from your pool instead of running them through the filter system. Hence, it is quite labor intensive and requires good skilled personnel or else, the dirt might blow up again in the pool, turning it cloudy again.

Why Is My Pool Light Green And Cloudy/Murky

  • Generally, a pool turns out to be cloudy or murkier due to following reasons:
  1. Over treat your pool with clarifier chemicals or other chemical sanitizers
  2. Treat your pool multiple times with clarifier
  3. Maintain improper chemical balance
  4. Maintain improper pH levels
  5. Make use of bad filters
  6. Improper dosage of chlorines while shocking the pool
  • Generally, a pool turns out to be light green when bad bacteria like algae grow in the pool. This happens when you maintain improper pH levels in your pool or improper chemical balance.
  1. If the pH level is below the recommended level, i.e. below 7.4 ppm, then the pool water offers a friendly climate for algae to grow in them. This makes the pool waters to appear green.
  2. If you maintain bad chemical balance, something other than just low chlorine, your pool turns out to appear green.
  3. If your pool filters are not working properly, this might result in debris to settle and clog the filters. You need to ensure that your filters run constantly throughout the day for 24 hours whenever the water start to turn cloudy or green.
  4. If the bottom and sides of your pool are not scrubbed regularly, you might be giving a chance for algae to grow.
  5. Sometimes, if there are any metals in your pool water and if you shock your pool, you might result in oxidizing the metals along with other dirt and this result in green waters.

Does Cloudy, Foggy, Milky, Murky Swimming Pool Mean The Same?

If there is an algae growing all around your swimming pool then, the pool waters start turning green. On the other hand, your pool can also turn you off if it looks cloudy. The water might not be green, but if it appears cloudy and not crystal clear, you might again not desire to enter the pool waters.

The water appears cloudy because of tiny particles that could not get filtered efficiently at the filtering system. The other reasons could be debris or chemical imbalance or over treating your pool with clarifiers.

Whatever the reason is, you pool will not look crystal clear if the above discussed reasons are not cleared for your pool. Depending on the type of tiny particles in the pool, or the type of debris, your pool might turn cloudy from light to heavy, also heating your pool with heater will help immensely.

In general, all of the terms like cloudy, foggy, milky or murky are used interchangeably. If the pool contains less tiny particles of dirt, it might look cloudy, which is a bit next to not being crystal clear.

  • If the concentration of dirt is much more, then the water might appear even more unclear, generally termed as foggy.
  • If the dirt levels are too high, then your pool might appear even higher than foggy appearance, giving a milky look.
  • You might term to muddy look as murky waters.

On the whole, finally, all the terms are used interchangeably depending on how you personally feel about the pool waters appearance. There is nothing much difference between these terms.

How To Get Rid Of Algae In Pool


Algae is a common word known to almost every pool owner. Algae, an aquatic organism contain chlorophyll and catalyses, when comes in contact with sunlight, photosynthesis the growth of this algae in water.

There are different factors that lead to growth of algae in your pool. It might be in-appropriate use of chemicals, carbon dioxide present in water, excessive exposure to sunlight or poor filtration of pool.

There are 4 major types of algae present in swimming pools irrespective of the fact whether they are in ground or over ground pools

  • Green Algae
  • Yellow Algae
  • Pink Algae
  • Black Algae

Out of these four algae, the most common is the green algae which affect your swimming pool the most. So, if you want to know different ways to get rid of green algae, read along. 

Steps to get rid of algae

Brushing the pool

This is the simplest of all the methods to get rid of algae from in-ground pools and above-ground pools.

Special attention should be paid to nooks and corners or behind the pool stairs, where the algae growth is maximum.

Be enthusiastic and brush wholeheartedly to eliminate the algae as much as possible by this easy method.

You can make this a family activity involving your kids to participate. I am sure they will amaze you with their energetic contribution. 

“Always use a brush that is compatible to the pool-type. Nylon brush for vinyl-coated pools and steel brushes for concrete tools are recommended”

Chlorine shock

Green water pools may look good and fascinating, but only the natural-pools not the in ground pools or the above ground pools.

Green water is a clear indication of algae in pool. As soon as you see such a condition, treat the pool with high quantity of chlorine.

This is also called shocking because of sudden treatment of the pool with high amounts of chlorine.

This is an effective measure but may take a few days (up to 5 days), depending upon the extent of deterioration of pool due to algae.

Optimize the PH level

Growth of Algae directly depends upon the pH level of water. Algae will start growing if the pH level of water is not in the desired range of 7.4 to 7.6. Algae will breed if pH level is between 6.5 and 12.5.

 Optimum pH level of water lets the chlorine present in water to work effectively thus maintaining the overall fitness of pool.

Sanitization of pool

Regular Sanitation of pool keeps the algae away from pool.  The pools must be treated with trichlor, which is considered an effective sanitizer but beware of using it in vinyl-pools since this chemical can bleach the walls and floor.

You can also use liquid chlorine. Another point to take care is that you should always sanitize the pool in evenings since UV rays from sun diminish the effect of sanitizer.

Once the pool is shocked with sanitizer, it is essential to circulate the water for at least 3 days.

Vacuum the residual algae.

Once the live algae are destroyed, it is time to rub off the dead algae, which can be done by manual vacuum machine.

 The other way to get rid of residual algae is by using the installed filter system, which may take few days to achieve 100% algae-free pool.  

Adding a flocculent will ease the work of vacuum since flocculent will clot all the algae together and will be easy to filter out.


“Flocculent treatment should be followed by chlorine shock treatment before using the pool, to achieve the desired pH levels."

Some Preventive steps

Regular checking

Certain parameters have to be checked in routine to maintain the freshness of pool water. These parameters are:

  • pH level
  • Chlorine level
  • Alkalinity
  • Cyanuric acid levels[/su_list]


Algaecide is one such chemical that will prevent the initial growth of algae in your pool. It can be added to the pool weekly, as a preventive measure for pool hygiene.

Removal of phosphates

Phosphate is one of the nutrients on which algae feed. To stop the breeding of algae in pool, phosphate should be removed and to do so, phosphate removal kits are available from swimming-pool chemical store.

Final Words

You will never appreciate  the complete draining of the pool to get rid of algae. So if you want to keep the pool clean and avoid trouble of treating the pool, it is better to stop the algae growth by taking the action now, than to repent later.
