How To Raise And Lower Ph In Pool

How to Balance Your Pool’s pH – HTH Pool Care

If the pH is low, a pH increaser is added to raise the pH. If the pH is high, pH Down is used. pH Down comes in two forms: liquid acid or dry acid.

Changes in the pH of pool water can be caused by many factors but one of the most significant cause is the sanitizer used. Since the sanitizer is the most frequently added chemical in pools, it can have a powerful impact on pH and overall water quality.

Of the sanitizers typically used in pools, chlorine is the most common. Chlorine comes in a variety of forms and varies widely in pH. For example, most tableted forms of chlorine have a very low pH and will tend to lower pH over time, while liquid chlorine is very high in pH and will tend to raise pH values. Salt is also very alkaline and will require frequent additions of acid to maintain the proper pH and overall water balance.

Changes in pH due to sanitizers or other factors can be minimized and controlled by the proper maintenance of the next chemical factor, total alkalinity.

Why Your Pool Ph Balance Is Important

Swimming pool water is treated with chemicals to disinfect and oxidize. An optimal pH balance is essential to maintain sanitary swimming conditions and the longevity of pool equipment. Although some other chemicals have been introduced into the market, the most common chemical used to treat swimming pools is chlorine.

Chlorine works in two ways:

  • It disinfects the water by killing bacteria and algae that cause waterborne illnesses. Bacteria in pool water can cause swimmers to suffer from diarrhea, swimmers, ear infections, and skin infections.
  • Chlorine also oxidizes dirt and debris particles that come into the water from swimmers and the environment.

Maintaining an optimal pH is important because it can impact the effectiveness of the chlorine and ultimately lead to unsanitary swimming conditions. In addition to health, it is also essential for the comfort of swimmers the optimal pH for swimming pools is the same pH as the human eye and mucous membranes. Unbalanced pH can lead to itchy and irritated skin and eyes for swimmers.

And if the health, safety, and comfort of swimmers are not enough, pH balance is essential for the longevity of the pool facilities and equipment. Overly acidic pool water is corrosive and will lead to the breakdown of equipment like pumps, ladders, and diving board structures. Unbalanced pH levels also wear down the pool liner and will create the need for more frequent replacements.

Measure And Add The Chemicals To Raise Ph In Pool

There is a certain amount of chemicals to use in a pool. Sodium carbonate is a common chemical that people use. Generally, sodium carbonate use is about 6 ounces per 0.2 pH in 10.000 gallons of water. You can measure by yourself how many chemicals are needed for the pool.

So, what are the steps? First, you must dissolve the amount of sodium carbonate powder into a bucket of pool water. It is done to make a slurry consistency.

Second, checking the pool circulation pump is important. The pool operators will walk around the pool. They will gradually pour the solution evenly into the pool.

It would be best if you waited 24 hours after that to recheck the pH level. Further, you can also determine whether to add or not to the treatment. This step needs more time because chemicals are usually slow in response to the treatment.

The range of 24 hours is the ideal time to take action of retreatment. Furthermore, the act also avoids the overcorrecting that can cause the pool back into excessive alkaline.

Why Is Cya Bad For My Pool Water

When using tablets that contain CYA you are building up the amount of CYA in your swimming pool. If your CYA level is higher than 50 ppm, the buildup of CYA in the pool water will significantly reduce the effectiveness of chlorine in killing germs, bacteria, and algae. Champion Liquid Chlorinator/Pool Shock does not add CYA to the swimming pool water.

Maybe yes, maybe no. Your pool water pH and Total Alkalinity can affect disinfection by chlorine. Chlorine is very slow to react at high pH levels, and can dissipate quickly at low pH levels. However, a pool could still be sanitary with good levels of Free Available Chlorine and effective filtration. However, the water may be uncomfortable for the skin and eyes, and will damage your pool over time. Its important to address chemical imbalances as quickly as possible to keep your pool experience a pleasant one.

How To Raise Pool Ph Level

Sometimes the pH level goes lower than needed. If you were learning how to lower the pH level of your pool and it accidentally went too low, its time to bring it back into balance.

As for what causes low pH in a pool, that varies:

  • Leaves and pine needles may give you a lower pH reading. This includes the leaves on the pool cover.
  • A heavy rainfall, especially in a city, can lower the pH. Rain is slightly acidic and will lower the alkalinity.
  • Many people lounged in the water. Body oils and sweat may mean a low pH for your pool.
  • You used dry or muriatic acid to lower pH. It may have been too much or there couldve been other factors at play. Sometimes its a challenge to get the pH just right.

Although a low pool pH is uncommon, you can still balance it out. The pool water is too acidic now. That means you balance it with alkaline substances. Raise pool pH with borax, soda ash or aerate the water. Washing soda and sodium carbonate are other names for soda ash.

To use soda ash to raise pool pH, follow these steps:

  • Follow the directions on the package to learn how much washing soda to use.
  • Run the pool pump and filter.
  • Sprinkle the washing soda evenly across the whole pool.
  • Wait an hour for the soda ash to distribute throughout the water.
  • Test the water and proceed accordingly.

Follow these steps to raise pool pH with boric acid:

Swimming Pool Care: A Guide To Perfect Ph Balance

Balance and harmony is the key to living. The same goes for your pool water. If everything is balanced, you will avoid a lot of potential issues such as cloudiness and algae.

Florence Kalitera from Zodiac Pool Care says water balance is important for a number of reasons.

She says not only does it help sanitise chemicals to work effectively but it also decreases the chance for water problems like cloudiness and algae growth.

She says it also prolongs the life of your pool equipment.

Florence shares tips on how to properly balance pool water

Keep your pool chemicals working

Maintaining the pH balance in your pool water will ensure you get the most out of your sanitising chemicals.

For instance, in pools with a low pH, your water is more acidic and will eat up the sanitiser faster. This doesnt give your sanitiser enough time to do its job properly.

Fight against cloudy water and algae growth

If the pool water is acidic, and your sanitising chemical isnt working as well as it should, then you are opening yourself up to water issues.

Your sanitisers job is to keep these issues at bay by constantly killing off the bacteria and debris that cause them.

Protect your equipment

Low pH causes acidic pool water. If this is the case, the swimming pool water will do whatever it takes to increase its pH level.

In fact, most manufacturers equipment warranties do not cover damage due to low pH.

Check Total Alkalinity And Make Appropriate Adjustments

Total alkalinity is the sum of all basic materials in the water. Low total alkalinity can cause significant and random fluctuations in pH levels. If you are still having trouble with low pH readings after adding the appropriate amount of soda ash, check your total alkalinity.

Sodium Bicarbonate is similar to soda ash and is used in swimming pools to raise the total alkalinity . Add 1.4 pounds of sodium bicarbonate per 10,000 gallons of water and allow the pool to circulate before testing again. Use our total alkalinity calculator to figure out the exact amount.

H2Oh! – Understanding the chemical composition of a healthy pool

A “balanced” swimming pool means keeping the five basic pool water components within their proper levels. These components work together to help the sanitizer work more effectively. For a visual representation, see the Pool House.

That’s why sanitizing and balancing are equally important in having a healthy pool. This is especially important when you are opening your pool for the season after winter, when refilling or with a new pool. Remember, water balance is constantly changing – test your water weekly!

Even with normal use, many unwanted items can be introduced to your pool. These items can prevent chemical treatments from doing their job, make the water unhealthy or unappealing, or all of the above. The two most important things to remember about healthy pools are that they must be sanitized and they must be balanced. Balancing your pool water and keeping pool chemicals in their ideal ranges will help ensure that your water will not harm your swimming pool or swimmers.

Water Balance Components

Total Alkalinity

Total alkalinity refers to how much alkaline is in the water, but you can’t fully know the importance of total alkalinity without referring to pH because the two influence one another. Low alkaline water leads to low pH and high alkaline water leads to high pH. A pool should have a total alkalinity level of 100 ppm.

It Can Damage Your Pool

If your pH level gets too high , youre looking at potential calcium scaling issues, which is a buildup of white scale or stains on your pool surfaces and even in your pipes.

Not only is scaling on your pool plaster a serious eye sore, but a buildup of scale in your pools plumbing will put strain on your filter system and other equipment, leading to circulation issues and even potential equipment failure.

On the flip side, if your pH level gets too low , the water can become corrosive, eating away at the plaster, metals, grout, and even pool tiles. This can also lead to some stubborn pool stains.

Not even pool vinyl liners are safe, as they begin to lose color, become weakened and prone to tearing, and ultimately cause your pool liner to fall apart if left unchecked.

Pool Ph Too High Or Too Low No Phroblem

Its important to know that anything that is added or that comes in contact with your pool water will have an influence on the pH, the greatest influencer being your sanitizer. While Clear Comforts AOP pool sanitation is pH neutral, chlorine can easily tamper pH levels. Understanding the chemical characteristics of your primary sanitizer is the first step in choosing the best pH chemical for your needs.

Whether you are building a new pool, renovating equipment, or just looking to optimize your current pool system, there are a number of options available for you to regulate your pools pH.

Wait And Retest The Pool’s Ph Level

Pool chemicals take some time to balance the pH. Let the pool water circulate for at least two hours.

  • After the chemicals have cycled through for a couple of hours, test the pH again.
  • Add more product if needed. If your pH is still high, follow the same steps as before.
  • If your pool pH is now too low, read on to learn how to raise the pH of your pool.

Wait until your pool water has a pH between 7.2 and 7.6. Once the water is properly balanced, youre cleared to go back in the pool. Ideal pool pH helps the chlorine work as it should. That way, you can stay safe and healthy as you swim.

Importance Of Balanced Pool Water

How to Balance the pH Level in Your Pool

Like I said earlier, keeping your water chemistry balanced is how you keep it safe for swimmers and bacteria and algae-free. But lets look at it a little closer.

You will use some type of sanitizer in your pool water. Thats what keeps it…well…sanitized.

And usually that sanitizer is chlorine. But its not enough to just throw some chlorine tabs in the dispenser or pour some solution in the pool.

You have to know how much chlorine is already there, how much to add, and when to leave it alone.

You can actually get too much chlorine in your pool. When chlorine levels are too high, it can cause skin and eye irritation and in extreme cases, even chlorine poisoning.

Chlorine poisoning can cause symptoms such as nausea, burning throat, itchy eyes, difficulty breathing and chest pain.

But aside from keeping the proper levels of chlorine in the pool, all the other levels have to stay balanced in order to help it do its job.

The pH level might be the second most important chemical to balance because it also directly affects how well the chlorine works.

If its too low, the chlorine will work well, but the water becomes corrosive, damaging equipment. It can also cause skin and eye irritation because the water is acidic.

And each level affects the other, either hindering it or boosting it too high.

So, keeping them all in the proper ranges is the only way you can keep your pool safe, clean and damage-free.

What Causes Low Ph Levels

Low pH levels lead to a number of issues from maintenance headaches like premature erosion of grout and corroded fixtures like ladders and diving boards. Low pH causes pool liners to become brittle and crack. It also causes discomfort for swimmers like burning eyes and itchy skins.

In most cases, low pH levels are caused by natural factors like a heavy rainstorm, overuse, and improper use of chemicals. Natural rainwater has a pH of 5 5.5, so it is naturally acidic. A substantial amount of rainfall can alter the pH of pool water to become more acidic. pH levels might also be low after a large party.

Dissolved bodily fluids can lower pH levels, so if you have had a lot of swimmers in your pool recently, overuse could be the culprit. And, sometimes, despite our best intentions, all of the concoctions on the market to try and manage pH levels can do more harm than good. It is easy to get pH levels out of balance when you are trying to DIY a solution to a pool water problem.

Why Shock Your Pool Water With Champion Liquid Chlorinator/ Pool Shock Rather Than Dry Shock

Champion Liquid Chlorinator/Pool Shock is safe and easy to use, as well as more economical and available. One gallon of Champion Liquid Chlorinator/Pool Shock is equal to 2 pounds of Calcium Hypochlorite. With Champion Liquid Chlorinator/Pool Shock simply pour around the perimeter of your pool water with the filter running, and you are finish. Champion Liquid Chlorinator/Pool Shock does not change the pH and leaves no residue. Shocking with Calcium Hypochlorite or Cal Hypo requires mixing of product with water before adding to the pool water. Also, Cal Hypo is not recommended in Salt, Vinyl Liner or Fiberglass pools because of the rick of fading the surfaces. Shocking with Cal Hypo will also raise the calcium hardness level in your pool water which can cause cloudy water and scaling of surfaces. High Calcium harness levels can cause poor circulation in your filtration system. Calcium Hypochlorite is a Class 3 oxidizer is very flammable.

How To Test Your Pools Ph Level

You can test your pool water with strips, a liquid test kit, or an electronic meter. No matter how you plan to test your pool water, make sure to take a sample using a clean bottle. Avoid pulling a sample near skimmers and return jets. Ideally, you want to grab a sample from the middle of your pool.

What Causes High Ph In A Pool

Balance Pool Water by Lowering pH Levels: Pool Time®

When your pools pH is too high, you might wonder what caused it. High pool pH is caused by a wide variety of issues. Here are common causes of an alkaline pool:

  • Algae can raise the pH.
  • Adding strong liquid chlorine, calcium or lithium hypochlorite chlorine may raise it.
  • Suddenly heating the water, whether from a pool heater or a string of sunny days, could up the pH.
  • Saltwater pools tend to be alkaline.
  • Adding water from the hose may raise it, depending on the content of your tap water.
  • For a new pool, pebble or plaster finishes raise the pH. Fiberglass and vinyl wont see this initial pH spike.
  • Time raises the pH in chlorinated pools. This happens naturally.

Reasons Why The Right Pool’s Ph Is Important

Here are some reasons why balancing your pools pH is important.

1. Cloudy water due to high pH Most minerals emerge from the solution as pH goes up. This will result in mineral deposits and murky pool water.

2. Damage to the vinyl liners due to unbalanced pH With high or low pH, vinyl will grow, which creates unappealing creases by absorbing water. If the water has too much pH, a vinyl can also age faster and need you to replace it sooner.

3. High pH levels renders chlorine inactive The further the level of pH in your pool water goes into the range of alkaline or basic, the less impact the chlorine will have. As a result, youll end up spending lots of money on chlorine and still have murky water.

4. Corrosion due to low pH Acidic water will start corroding everything from pool pumps and other pool systems to diving board bases, slides, and ladders. Low pools pH will even etch or corrode the plaster in gunite swimming pools.

5. Skin and eye irritation due to low pH acidic pool water will not only irritate the nasal passages and eyes but will also strip your body of its natural oil. This will leave you with hair brittle and itchy, and dry skin. Additionally, similar physical problems will occur if the pools pH becomes very high.
