Does Low Ph Affect Chlorine
Low pH has a huge impact on chlorine. Chlorine needs a pH of at least 7 to work properly, so if the pH in a pool is below this level, it will have severely reduced effectiveness.
This means that even though you may be adding enough chlorine for effective cleaning and disinfection purposes, low pH levels can increase bacteria counts dramatically which could lead to skin irritation or eye damage.
To avoid these drawbacks, keep your water at an acceptable pH range by monitoring regularly with a test kit and adjusting accordingly when necessary.
How To Raise The Ph Level In Your Pool: The Easy Way
Pool water is a delicate balance of chemicals. If the pH in your pool drops below 7, it can cause serious damage to your pools surface as well as chlorine loss.
This article will give you a step-by-step guide on how to raise ph in your pool with three inexpensive solutions: Soda ash, baking soda, or pH increaser.
How To Raise Ph In Pool By Using Sodium Carbonate
- It is imperative that the instructions on the label of the packet must be carefully read. The manufacturers may have important notes that will affect the method of application.
- Based on the results of the pool test kit, ration out the amount needed and add three-quarters of the recommended dosage for the pool. Re-test to see if more sodium carbonate is needed to reach the proper pH level.
- Since sodium carbonate comes in powder form, double check if manufacturer suggests diluting the chemical first before administering to pool water. If dilution is necessary, follow the instructions carefully.
- If no dilution is necessary, take caution in adding the sodium carbonate during windy days. If unavoidable, apply downwind to avoid powder getting on skin or clothes.
- Add the sodium carbonate where the water return jet sights are. This will allow for the powder to spread fully onto all parts of the pool. Never add the sodium carbonate where the water inlet sights are or where it can be easily pulled into the pump or pool filter.
- There is no need to use the pole brush to spread the powder around as sodium carbonate is easily dissolved.

How To Raise Ph Level In Pool Water
As a responsible pool owner, its your duty to know how to raise pH level in pool water? You should also know the desired pH range of pool water. pH is the most important parameter that needs to be maintained to balance your pool water chemistry.
If your pool water pH is low then it can cause many serious issues like irritation, sickness, burning of eyes, etc.
In this in-depth guide, I will cover all the pH-related concepts in detail in a super simple way so that you can understand and implement them without any doubt.

Factors That Raise Ph In A Swimming Pool
So why does the pH tend to climb in swimming pools? You may notice pH almost never naturally drops over time…so there must be something going on. It turns out, while pH is controlled by the concentration of Hydrogen ions, practically speaking, pH is also determined by the amount of carbon dioxide in the water. And there are several factors that affect CO2 levels in pools, and cause a pool’s pH to lower or rise. So let’s talk about some of them.

What Is Ph In Pool Water
The chemical formula of water is H2O.
H2O is made up of two ions H+ and OH-
H+ is the acidic ion that represents acidity and OH- is the basic ion that represents the basicity of water. As per the scientific definition, pH means the concentration of H+ ions present in water. The more the H+ ions present the more acidic water will be.
The formula of pH is
pH = -log
The pH scale ranges between 0 to 14.
< 7 is the acidic pH
> 7 is the basic pH
7 is the neutral pH
7.4 pH is the perfect number for pool water. Normally, 7.4 -7.6 considered the ideal pH range for pool water.
What Is Pool Ph Level
pH levels refer to the hydrogen ion present in the water. On average, the normal scale for swimming pools is 7.2 and 7.8.
Achieving this number isn’t always easy, considering several external influences which affect the rating of your pool.
Such include the addition of chlorine, chemical, humans, bacteria, just to name a few.
Importance of Maintaining Good pH Level
Maintaining the ideal rating for your pool keeps the water sanitary and increases the longevity of your equipment. Plus, it also affects the pH and total alkalinity of your pool water.
Unknown to many, reaching the perfect pH balance affects how it interacts with other chemicals and anything else you put. One great example is chlorine.
Chlorine does wonders at cleaning a pool and keeping it sanitary.
But, with the wrong rating and total alkalinity levels, using chlorine won’t do much of its job. It’ll be a waste of time and can cause some serious physical manifestations.
You’ll start feeling itchy, your skin feels irritated, and your eyes have that burning sensation. And don’t let us even get started with muriatic acid or cyanuric acid.
It can also cause some serious damage to your pool equipment. A swimming pool water is too acidic once the rating goes down, and it corrodes your equipment.

How To Raise Your Pools Ph Level With The Right Chemicals
For balanced pool water, keep the pH between pH of 7.4-7.6. And there are two different chemicals you can use to raise the pH in your pool:
- Baking Soda aka sodium bicarbonate .
- Soda Ash aka sodium carbonate .
Note: Before you add any chemicals to your pool, make sure you know exactly how much water your pool holds so you add the correct amount of chemicals to raise your pH and other levels.
If you decide to use baking soda, just note that this chemical will also increase your alkalinity level. So if both your pH and alkalinity are low, this is the right chemical to use to raise each one.
What Is The Difference Between Baking Soda And Soda Ash
There is a big difference between the two. Baking soda is sodium bicarbonate and this has a pH of 8.4. Soda ash is sodium carbonate and this has a pH of 11.6, so it is far more alkaline than sodium bicarbonate.
It takes more baking soda to increase the pH levels by the same amount as it does soda ash which is more alkaline. Because of this it is easy to add too much soda ash and increase the pH levels more than is desirable. If you do this you will have to add something such as muriatic acid to bring the levels back down again. In other words, it is easy to end up chasing your tail, turning your pool into a chemical bath.
Baking soda is likely to increase the total alkalinity in addition to raising the pH whereas soda ash will have less of an effect on total alkalinity. So if your total alkalinity is close to being correct but your pH is low then use soda ash.

Measure The Water Volume In The Pool
Knowing exactly the amount of water in the pool is essential before you come to the main part of raising the pH level. When adding the chemical, the amount will depend on the pool amount of water.
For long pool owners, you can know exactly how many gallons are in the pool. But, if you just bought a new house with a pool, you might call the pool operator asking for help.
Pool Ph Is High Total Alkalinity Is Low
Low Total Alkalinity under 80 ppm can cause pH to be unstable and erratic. To raise it, add Alkalinity Increaser . Keep in mind that this will also slightly raise your pools pH level, but not as much as the Total Alkalinity level. Once TA is back in balance, you can adjust pH. Just like in the scenario above, you may need to make repeated alternating adjustments to get the levels just right.

Raising Ph Level By Aerating The Pool
This simple and straightforward method takes several days to accomplish but is a perfect solution for pools that stubbornly maintain a low pH level. This method is simply done by turning the pools water features on and make sure that the water jets point towards the surface. The purpose of this is to ensure water surface is active to remove carbon dioxide that is present in the water. By using this method, it raises the pH level without interfering with the pools total alkalinity.
Getting An Accurate Water Test
One more tip! For correct pH and Total Alkalinity testing, a titration test is generally much more accurate than test strips. We like to recommend the Taylor K-2005, but if the price tag is too much, take a look at the less expensive Swimline 4-in-1 for a reliable pool pH and Alkalinity test kit.

How High Should The Pool Orp Level Be
Pool water with an ORP level above +750 mV is considered sufficient, but the measured level of the redox voltage varies depending on the type of pool.
As mentioned above, the redox voltage is always measured considering the pH level and the free chlorine in your pool a generalized statement is difficult.
The following table shows how high the pool ORP level should be in your pool water.
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.

How To Add Acid
When you add acid, pour it into the deepest part of the pool, while the pump is running and circulating the water. Wait at least an hour before using the pool if you added a lot of acid, wait 24 hours and test the pH before using the pool.

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.

Keep Your Water Well Circulated
You could have Dexters laboratory in your pool, but if the water isnt being circulated, you wont see much benefit from all those chemicals.
Its important to check that your water is moving through your pool filter system without restriction, and that the circulation cycle is optimized, helping to keep your chemistry in check.
Much of this ties back to proper maintenance, particularly when it comes to your pool pump and filter, as well keeping things like calcium scale from clogging up your pipes.
But there are a few other things you can do, including:
- Installing a flow meter to check the flow of water
- Installing some water features to keep water moving
- Directing your pool jets to improve the overall flow
- Checking your pump sizing is correct to move enough water
- Making sure youre running your pump long enough
- Checking your water level is at the right level for the skimmers
- Using a pool cover to limit contamination

Use Aeration To Raise Pool Ph
Looking to raise pH without affecting Total Alkalinity? You can sometimes raise the pH through aerating the pool water. Yep, just add air! Its the same reason hot tubs and spas often suffer from high pH issues. Although this will raise your pH, its important to note that this isnt an exact science, and results will vary by pool.
You can aerate a pool by bubbling air through the water, agitating the surface, spraying droplets through the air with a pool fountain, or even just playing and splashing around in the pool. During the hot summer months, this method also can be used to lower pool water temperature.

Maintaining a balanced swimming pool pH is a vital part of swimming pool maintenance. Not only does the proper pH protect your metal fittings and the walls of your pool, but the right pH range is also what makes swimming in the water pleasant instead of an itchy, burning trial. The correct range for a swimming pool is a pH of 7.4 to 7.8. If you are testing your pool and the pH registers as too low, try the techniques below to raise your pH.
1. Check Your Reagents
The first thing to check when your test indicates a low pH is whether your test reagents are still good. Reagents should be replaced every year and should never be mixed between test kits. If your kit is old, try getting a new one and testing again.
2. Add Soda Ash
If your pH is still low, try adding sodium carbonate, commonly called soda ash. Never add more than two lbs of soda ash per 10,000 gallons of water in your pool in any single treatment. Distribute the soda ash over the whole of the pool surface, starting in the deep end. Make sure that the pump is circulating to distribute the water and then wait an hour or so before testing again. If the pH is still too low after an hour, you can add more soda ash.
3. Check Your Total Alkalinity and Add Baking Soda

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.
