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.

What Can You Put In A Pool To Make The Ph Level Go Up
The acidity or alkalinity of pool water and other substances is measured using the pH scale, which assigns the material a pH value ranging from zero to 14. The optimal pH range for pool water is 7.2 to 7.8, or slightly alkaline. If pool water is acidic, with a pH below 7.0, it can corrode metallic features and may damage pool wall materials, encourage odor and leads to eye irritation. Alternatively, if the pH is too high, the disinfectant in the pool can become less effective, water clarity is adversely affected and scale deposits can occur.
Balance Is Important For Ph

How To Deal With High Ph Levels In Your Pool
Generally speaking, if you find that your pools pH value is higher than 7.6, well suggest you do something about it immediately. And perhaps the best, quickest and most effective solution is to use pH minus an acid you can add to the pool to lower the pH level.
Coming in powder form, pH minus is pretty easy to use you basically have to spread it over the water surface. Its however important to note that you to dissolve the granulate in a bucket of water before using. Doing this will prevent the acid from causing unnecessary damage to your pools lining and you looking for remodeling and repair services.
Bonus: Factors That Lower Ph
For the most part, pool pH will rise over time, so there are not too many cases where a pool’s pH remains low, or continues to lower over time. That’s why we have devoted an entire article to rising pH, and a mere bonus segment within it for lower pH. In a cementitious pool , pH will almost always rise. This segment is really more for fiberglass and vinyl liner pools.
Some reasons for pool pH being reduced or staying low include using acidic chlorine like trichlor and getting a lot of rain. Rainwater tends to be acidic, and it can be even more acidic the closer you are to a major city. Another thing: rainwater contains no calcium carbonate, meaning it’s not only acidic but super aggressive on the LSI. Other things that can lower pH in a pool are leaves and pine needles. This is an underestimated factor, especially during the offseason.
Climates that get a lot of rain or snow in the winter time, combined with leaves and pine needles on a mesh cover? Yep, that pH is going down in the short term, probably making the water low on the LSI, so it has to correct itself. This leads us into entirely different conversations about types of calcium dusting in pools that occur during the winter, as well as other issues like pool crystals and calcium formations. Fortunately, we have already written about those topics.
Chemicals that lower pH
To lower pH, you must increase dissolved CO2. There are two ways to do this.

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.
Why Should I Raise My Pool Ph
Our pool chemistry has ranges, and we should do our best to maintain the chemicals within those ranges. When things are out of range, too high or low, they can cause problems.
Acidic low pH levels can lead to maintenance headaches like erosion of tile, grout, coping, and the corroding of plumbing and pool ladders. Low pH can also cause discomfort for swimmers like burning eyes and itchy skin.

What Ph Should Your Aquarium Be
The pH of your tank will depend on the species of fish that you keep. When designing their perfect aquarium, your job is to recreate their natural habitat as best as you can. This includes pH.
It is easy to find out the preferences of your fish if youre unsure. We recommend an ideal pH on our various species care guides.
It will also be mentioned in fishkeeping books, or you could ask staff in pet stores.
You might notice that each type of fish tank tends to have a different pH. Tropical tanks are usually between 6 and 7.5, while marine tanks are around 7.5 to 8.5, with reef tanks being at the higher end of this range.
There are many exceptions to this though, which is why it is always safest to check the specific needs of your fish.
For example, African Cichlids prefer more alkaline conditions than most tropical fish. Some are kept at a pH of up to 8.5.
Remember to check that your pH is suitable for any other life in your aquarium, such as plants or invertebrates.
What Does Baking Soda Do For A Pool
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient. You can maintain your pool for a fraction of the cost by going straight to the source and using pure baking soda in your pool.

It Can Make Your Water Cloudy
pH doesnt directly make your pool water cloudy. Instead, its often a side-effect of the issues weve already covered.
The scaling caused by high pH water leads to circulation issues, which leads to cloudy water. The corrosion caused by low pH water creates debris, which also leads to cloudy water.
And it doesnt stop there.
Since your pH level dictates the effectiveness of your sanitizer, improper pH can lead to poor sanitation. This turns your pool into breeding ground for various types of algae, bacteria, and viruses, and can also result in cloudy or green water.
Can I Use Baking Soda To Raise The Ph
Yes you can. But there are a couple of drawbacks.
- Baking soda is only about half as efficient at raising pH.
- Baking soda not only raises the pH, it also raises the total alkalinity. What that means in practice is that you should only use baking soda to raise pH when the total alkalinity is significantly below its desired range of 80-120 ppm. If the total alkalinity is close to or within the 80-120 ppm range, the danger is that baking soda will over-raise the total alkalinity: and then you will suddenly be two chemical levels out of whack instead of just one.

How To Lower Alkalinity In A Pool
If the alkalinity of the water is too high, i.e. more than 120 ppm, its an easy fix to lower the alkalinity of the water.
First, make sure the water pump is on and take a current pH measurement.
Add one quart of muriatic acid or 2 pounds of dry acid at a time around the perimeter of the pool.
Let the acid mix in the water for about an hour, then test the water again. Maintain a water pH of about 7 and keep adding pool acid in small increments until the correct alkalinity level is reached.
Once the alkalinity level is correct, allow the pH to climb naturally by circulating the water.
Only add soda ash to raise the pH if the pH stops climbing after 1 week.
Directing Downspouts Into The Pool
This technique is not commonly used because it is a bit difficult. But if you can do it, you definitely should.
If youve used the test strips to check the pH level of your pool and it is alkaline, you can reduce it by using rainwater. Rainwater has a pH of about 5.6. When mixed with the pool water, it will lower the pH.
The problem with using this technique is that you haveto continue checking the pH. It must be balanced and within the neutral rangeat all times. Because rainwater has low alkalinity levels, it may not be soeasy to maintain. The chlorine in the water may corrode your pool and pipes ifyou dont monitor carefully.
However, rainwater is a very good alternative if youlive in an area where water is expensive.

Stay On Top Of Maintenance
Regular testing allows you to figure out whats going on with your water and your pool ahead of time. Regular pool maintenance prevents any anomalies from turning into potential problems.
In terms of water chemistry, this applies to everything we mentioned above, adding the necessary chemicals to keep them within the stated ranges.
Heres how to adjust if needed:
- Water pH can be lowered by adding muriatic acid or sodium bisulfate to your pool. pH can also be raised by adding sodium bicarbonate or sodium carbonate .
- Total alkalinity can be lowered by lowering pH , and raised by adding sodium bicarbonate which raises alkalinity more than it does pH.
- Sanitizer level, assuming youre using chlorine, the chlorine level can be lowered numerous ways but the easiest is waiting for the sun to burn it off. It can be raised by adding more chlorine, obviously.
- Pool stabilizer can be lowered by draining or diluting your water, and raised by simply adding more cyanuric acid. Keep in mind that most slow-release chlorine, like chlorine tablets, are already stabilized.
- Calcium hardness can be lowered by draining or diluting your water or using a pool clarifier or flocculant to clump excess calcium. It can be raised by adding calcium chloride or using a calcium based chlorine, like cal hypo.
In terms of surfaces and pool equipment, regular maintenance encompasses everything from cleaning and backwashing filters, to vacuuming and scrubbing surfaces.
Phroblem How To Balance Your Pool Ph Low Or High Levels
Do you know the reason why lemon juice or certain soaps burn our eyes? Its because our eyes are sensitive to substances that are too low or too high in pH. Similar to your eyes, its critical to make sure your swimming pools pH is in the ideal range.
When maintaining your swimming pool water, pH is the most important element of balancing water chemistry. But before you learn how to regulate your swimming pool pH, it is important to know what pH is and how it can affect the comfort, equipment, surfaces and sanitation of your swimming pool.

What Are Pool Ph Levels
pH, or potential hydrogen, is how well a solution attracts hydrogen ions. It can tell us how alkaline or acidic a liquid is. You measure pH on a scale from zero to 14. Zero means the solution is acidic, while 14 indicates the solution is basic or containing more OH ions than H + ions.
A neutral solution such as pure water falls in the middle of the scale with a pH of seven. A good level for pool water is a pH of 7.5, which means its slightly basic. Low pH can be caused by:
- Debris such as leaves, bugs, and grass clippings
- Human secretions such as body oils, sweat, saliva, and urine
Why Should You Lower Your Pool’s Ph Balance
If your pool has a pH balance that constantly gets a little too high, you could start to notice some pretty significant problems.
It can even be dangerous for swimmers, killing the chlorine benefits and posing some serious health concerns.
Here are some things you might see:
- Skin and eye irritation
- High chlorine demand
- Cloudy water
Clogged filters and scaling may not sound like a big deal, but when you consider that it can affect circulation and put a strain on your pool equipment, you might start seeing dollar signs.
Imagine, for example, that you get some severe scaling in a pipe, which causes your water not to be able to move through it at the same speed.
In this case, your pump is still pushing water through your pipes just as fast as it was before, but now your system cant quite handle it.
This can cause pipes to burst or your motor to burn out, both of which can result in some pretty expensive repair bills.

Reducers To The Rescue
To bring down pH, use a made-for-pools chemical additive called pH reducer . The main active ingredients in pH reducers are either muriatic acid or sodium bisulfate . Reducers are readily available at pool supply stores, home improvement centers and online.
Muriatic acid is powerful its used to etch concrete and you need to be careful when adding the chemical to your pool. It comes in liquid form, so you need to protect yourself from accidental spills and splashes. Always read and follow the manufacturers directions for safe handling, applying and storing of muriatic acid. A 1-gallon bottle is about $45.
Sodium bisulfate comes as dry granules and is considered easier to add and safer to handle than muriatic acid. Nevertheless, it should be handled carefully. Protect eyes and skin, and wear a dust mask to avoid inhaling any dust from the granules. A 25-pound bucket costs about $50.
The correct amount of a pH reducer depends on the water volume of your pool and its current pH level. Reducers usually come with a guide that takes into account the variables and calculates the proper amounts of pH reducer to add to your pool.
Basic Sanitizers That Raise Ph
High pH can cause cloudy water and create scale, which is a crystalline buildup of inorganic materials, like calcium, that creates a white film around your pools water lines.
Higher pH can greatly diminish sanitizer and disinfectant performance in the water. It is important to understand that you get higher chlorine efficiency at a lower pH so it is advisable to operate on the low end of the range if your saturation index allows. For homeowners, the most common primary sanitizers that increase pH are:
- Sodium hypochlorite: Commonly known as liquid chlorine or bleach, sodium hypochlorite has a natural pH of around 13 and is rarely used on pools alone because its very unstable.
- Calcium hypochlorite: Calcium hypochlorite, or cal hypo, is both an oxidizer and sanitizer and is the most frequently used in the pool industry. With a pH around 11.8, depending on the concentration, cal hypo will require acid remediation to help lower the pH.

What Happens If The Ph Is Too High
When pH gets excessively high, the water becomes overly soft. The effects? Well, just think skin irritation alongside dryness and red eyes. Too high a pH level can also damage swimwear including swim caps and goggles. Thats not all water with a pH thats too high can cause scaling on pool equipment which in turn hampers the effectiveness of the pools circulation system and increases the cost of maintenance.
Its also worth noting that too high a pH level can cause you to spend more on chlorine. Why? Well, its only because soft water causes the chlorine to work less effectively. In other words, youll need to add much higher amounts for proper disinfection.
