What Is Ph Anyway
pH stands for power of hydrogen. The pH scale measures the logarithmic concentration of hydrogen and hydroxide ions. This is water, = H20. When both types are equal in concentration, the pH is 7.0, which is considered neutral.
When the concentrations arent equal, thats where the problems start. PH is ranked on a scale from 1.0 to 14.0. The lower the pH of water, the more acid is in it, or the more acidic the water is. The higher the pH, the more base, or alkaline, it is. Our friends at UMassAmherst tell us, pH affects many chemical and biological processes in the water and different organisms have different ranges of pH within which they flourish.
How To Lower Ph In A Swimming Pool
Balance is essential in all things in life as well as for your swimming pool. The pH of the pool is a perfect chemical factor. Proper pool chemistry levels are those pools that have balanced levels of total alkalinity, pH, and Calcium Hardness.
If your swimming pool chemistry levels do not function, it is hard to get the balance again. So, keep your swimming pool balanced to protect your pool equipment and have comfortable swimming.
How Does Aeration Increase Ph Levels
When you aerate, you are exposing the water to more oxygen in order to do away with some of the carbon dioxide. When carbon dioxide mixes with water, it forms an acid we call carbonic acid, which lowers the pH levels. On the other hand, when acid is removed from the water, the pH level rises. Aeration literally removes carbonic acid from the water, which then raises the pH levels.
I always recommend natural aeration because with this method, you cannot over-aerate your pool, which is a very common issue when aeration equipment is used.
As a matter of fact, over-aeration is dangerous since you need some carbonate to act as a pH buffer. Carbonate is useful in plaster pools because it prevents the plaster from dissolving. In the case of over-aeration, pH will rise above the recommended levels while calcium carbonate will reduce below the required level. To fix this, you’ll need to adjust the pH and calcium carbonate levels to avoid any further damage.

How To Lower The Ph Level In Your Swimming Pool
First and foremost you should get a test kit with fresh reagents from a verified seller. This will help you determine the pH level and ensure that you use the right chemicals for fixing it in the right quantities. Test the pH level before you use any of these chemicals. That way, after proper application, you can retest and see the difference of the results. You can use Blue Connect for testing the pH level, temperature & salinity all at once. It also recommends the required amount of chemicals.
Use dry acid or liquid acid to control the pH level in the pool:
Can You Swim In A Pool With Low Ph
Yes, to an extent.
Unless youre extremely sensitive to pH, youre unlikely to feel the effects of acidic pool water until it becomes very acidic.
Were talking about a pH level of well below 5, and a level that low is almost unheard of in the pool industry.
Instead, its the inefficiency of your sanitizer that poses more of a risk at lower pH levels, potentially leaving you exposed to all kinds of contaminants in the water.
Important: Many pH testing kits have a lower limit on their measurements, meaning anything lower will always come back as the minimum possible reading. If you get the minimum pH, use another test kit to find the true pH.

What Is Ph In The Pool And Why Is It Important
pH is used to describe a scale of acidity or basicity of a solution. Ranging from 0-14, a pH of 7 is neutral, anything less than 7 represents an acidic or low pH solution, and anything more than 7 represents a basic or high pH .
The pH, as well as alkalinity, is probably the most important value to stay on top of in your pool. Its best to maintain a slightly neutral pH between 7.4-7.6 with an alkalinity level between 80-120 ppm.
Factors that cause pH to change in your pool:
- airborne debris
- swimmer wastes
When the pH shifts out of balance, it can wreak havoc on your pools chemistry and balance as it directly affects some of the chemical reactions that take place.
Ending Thoughts On How To Lower Ph In A Swimming Pool

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:

pH is the term used to refer to the degree of activity of an acid or base in the water. It is the most important chemical factor to be maintained in swimming pools. pH is measured on a scale from O to 14 with 7 being neutral. Pool water pH is best when kept in the range of 7.2 to 7.8.
A value of 7 to 14 is considered basic with 14 being the greatest base activity. Another word for basic is alkaline however, this is not to be confused with total alkalinity. pH and total alkalinity are not the same but can be influenced by each other.
A pH value between 0 and 7 is considered acidic with 0 being the greatest acid activity and getting weaker as it approaches a value of 7. When pH remains below 7.2, the water is considered to be corrosive. This means etching of plaster and metals in equipment such as heat exchangers will result. In addition, it is more difficult to keep chlorine in the pool because while more effective as a sanitizer at the low pH, chlorine is also much less stable resulting in the consumption of larger quantities of chlorine than would be used at normal pH levels.

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.
How Much Muriatic Acid To Lower Pool Ph
The amount of muriatic acid needed to decrease pool pH will depend on your pools water volume, pH level and alkalinity level. Remember that when you lower alkalinity, the pH will follow.
Youll need approximately 35-60 fl oz of muriatic acid per 10,000 gal of water to reduce alkalinity by 10 ppm. Use the appropriate chart below to help calculate the approximate amount of muriatic acid needed to reduce pH and alkalinity.
Pro Tip: Its best to add acid in smaller batches, then retest and add more if needed. Otherwise you risk seesawing the pH levels.

What Ph Is Considered Too High
pH is measured on a scale of 1 to 14.
The lower the reading, the more acidic the water. Specifically, a pH level of 1 is very acidic, a pH of 7 is neutral, and a pH of 14 is very basic.
An optimal pH level for a saltwater pool sits between 7.2 and 7.8, so anything above 7.8 is considered too high.
The side effects of high pH become more severe the more basic the water becomes, so a small and temporary rise above 7.8 isnt something to cancel your vacation over.
Effects Of High Ph Levels In Swimming Pool
Once you start to notice the cloudy water of your pool, it’s time to second guess whether you should take a dip or not.
It’s one way to tell that your pool’s pH base is high, and you probably shouldn’t take a dip just yet.
High levels of pH in your pool water have some severe risks for yourself and pool surfaces.
You’ll notice that your skin starts to get irritated. Your eyes might even start to have that burning sensation because of the water.
High pool pH also affects your pool equipment. It can create clogged pipes and filters, vital for cleaning your waters.
You might also notice that your pool water requires chlorine more than usual. No matter how much chlorine you use, it won’t be effective if the pool pH is too high.

What Is Ph And What Should It Be
pH simply means the waters total acid-alkalinity balance.
If the balance is off, problems can and probably will occur in your pool or spa.
Any element added to the water, be it sweat, sunscreen or leaves or bugs will cause the pH to change.
If the water becomes too alkaline , the water can become cloudy or it can cause scaling on the plumbing equipment and on the pool lining something that can be costly to fix.
If the water is too acidic , it can cause etching or corrode the metallic equipment. In the worst-case scenario, highly-acidic water can give you and your guests skin rashes or irritations.
For these reasons, its important to monitor pH levels closely.
Its also important to note that the water will need to be tested more frequently during periods of high usage due to an increase in by-products from swimmers or simply from dirt that gets tracked into the pool.
What Happens In A Low Ph Swimming Pool
On the other hand, swimming pool water with low pH levels is acidic this you can actually feel the difference as you take a dip and swim. If you swim in an acidic pool, expect skin irritation and burning eyes the moment you open them underwater.
Just like in an alkaline pool, chlorine and other chemicals may not be effective in pool water with low pH. Metal parts of your pool can also corrode, and vinyl linings may wrinkle if the water is too acidic.
