Baking Soda to Raise pH and Alkalinity in Pools
Most people know that chlorine is an important chemical in keeping pool water safe for swimming. But adding too much chlorine can lower your pool’s pH as well as its total alkalinity. When alkalinity falls, it is more difficult to maintain a stable pH. Plus, a lower pH and alkalinity of your pool water creates several negative effects, from itchy skin and stinging eyes for swimmers to corrosion of your pool ladders, liner, or other components.
When your water’s alkalinity is too low, any chemicals you add will exponentially affect the pH, creating a condition known as pH bounce. You’ll also need to add more chlorine to get the same sanitizing effect, and your swimmers will complain. Overall, pool water with inadequate alkalinity levels can be frustrating and costly.
Fortunately, there is a simple and cost-effective way to maintain your pool’s alkalinity and pH. You might use it in your cookie recipes or to freshen your fridge. This handy tool for pools is none other than Arm & Hammer baking soda, although you’ll need pounds of it rather than a pinch.
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.
Using Baking Soda to Increase Alkalinity
Follow these steps to test and raise your pool’s alkalinity and pH with baking soda.
- Test your pool’s alkalinity daily. Ideally, your pH is between 7.2 and 7.8 and the alkalinity is between 110 and 150 ppm (parts per million).
If your alkalinity level is lower, and especially if less than 80 ppm, then you need to raise the pool water alkalinity. - Purchase baking soda in bulk (available in pouches up to 15 lbs.). You will be adding anywhere from 1.5 lbs. to as much as 8-10 lbs. of baking soda to your pool, depending on how low your alkalinity is.
- Determine amount to add. You’ll need to figure out how much baking soda to add to your pool. Pool chemical measurements are based on 10,000 gallons of water. If your pool is larger or smaller, you’ll need to adjust your math. A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool’s pH tested below 7.2, add 3-4 pounds of baking soda. If you’re new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount. After retesting, you can always add more if the level is still low. Otherwise, you could swing too far in the delicate pH balance and need to add an acid.
- Add baking soda to the pool. Sodium bicarbonate is packaged in powder form and can be sprinkled directly into your pool water. Spread in wide arcs across the pool’s surface to avoid dumping it all in one spot. Beware of adding baking soda on a windy day, as the powder can go airborne.
- Wait at least six hours. Let the baking soda dissolve into the water. Turn on your pool’s circulation system to help it disperse.
- Retest and repeat if needed. Between 6 and 24 hours after you added the baking soda, retest your pool’s pH and total alkalinity. If the pH is below 7.2 and the alkalinity below 110 ppm, then repeat these steps.
Correcting Common Pool Problems with Baking Soda
Baking Soda and Green, Blue, or Yellow Algae
If you have algae in your pool, you’ll notice dull green water, slimy walls and pool bottom, and a slippery pool surface. You’ll need to use an algaecide to kill the algae and superchlorinate your pool to clear the water.
After this treatment, test your pH and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and pH to between 7.2 and 7.8.
Baking Soda and Pool Corrosion
If you’re noticing corrosion on your pipes or ladders, or pits on your pool liner or tiles, you have very low water alkalinity. Test and add Arm & Hammer baking soda according to the instructions. You will typically need at least 8 lbs. if your levels are low enough to cause corrosion.
Scaling Buildup on Pool Surfaces
Too much calcium and pH as well as high alkalinity levels are culprits for pool scaling. So, too, is hard water. Stop using calcium-based disinfectants and keep your pool’s alkalinity between 80 and 110 ppm. Test your levels and carefully add a pool acid, such as muriatic acid to lower pH to below 7.8. If you go too far, add baking soda sparingly to reach the appropriate levels.
Cloudy Pool Water
If your pool water is cloudy or murky, there could be a number of causes.
Check your pool’s filtration system; often the problem lies there. Also test your water’s hardness. If your water is naturally hard, or contains a lot of minerals, you will want to stop using any products containing additional calcium and keep your alkalinity levels lower than 110 ppm (but higher than 80 ppm). To cure cloudy pool water, superchlorination is usually the easiest fix. Be sure to test your pH levels after the hyper-chlorination treatment, and slowly add baking soda to your pool water, if needed, to get to between 7.2 and 7.8. Higher pH levels can lead to cloudiness.

What Does Baking Soda Do for a Pool?
istockphoto.com
Q: I just moved into a new home with a pool in the backyard. I have never had my own pool and am new to all the necessary maintenance tasks. I’ve heard that you can use baking soda for your pool, but I don’t know exactly how it helps. What does baking soda do for a pool? Does baking soda raise pH?A: Buying a home with a pool can be exciting, but it’s also a big undertaking—one of the things some people fail to consider before putting in a pool. You are right in thinking that baking soda (sodium bicarbonate) can be helpful with pool maintenance; it is a versatile product that can help with many home-care related tasks.
So, what does baking soda do for a pool? Baking soda can actually come in handy for a number of pool maintenance tasks.
Read on to learn more about what baking soda can do for pool water, how to add baking soda to a pool, and whether it is the product you’ll need to help maintain your backyard pool.

What Does Baking Soda Do for a Pool?If you’re at all familiar with basic swimming pool chemistry, then you may already know that the water’s pH level should be between 7.4 and 7.6, and definitely not outside of the 7.2 to 7.8 range. If the pH drops too low, it can irritate the eyes of swimmers or cause their skin to itch.
Sodium bicarbonate for pools can help to raise the pH when it drops too low. If you’re wondering how much baking soda it takes to raise pH in a pool, the amount you’ll need can vary based on the size of your pool and the exact pH reading.

In addition to helping to raise the pH of a pool, baking soda can be the answer to the question of how to raise alkalinity in pool water.
It is naturally alkaline, so when you pour baking soda in the pool, it will raise the alkalinity, along with the pH.

1. Baking soda improves clarity and softness of pool water.There are a number of potential causes of cloudy pool water, including problems with the pump or filter, chemical imbalances, hard water or outside environmental factors. To determine whether baking soda may be able to help you address cloudy water issues, test the pH and alkalinity levels.
The pH should fall between 7.2 and 7.8, and the alkalinity level should be between 80 and 120 ppm (parts per million). If the readings for both pH and alkalinity are low, then add baking soda to your pool. Rebalancing the pH and alkalinity can help to clear up the cloudy water.
2. It reduces corrosion on pool parts and equipment.When either pH or alkalinity are too low, the water can be corrosive to ladders, pipes, and other metallic components of the pool.
Lower pH and alkalinity levels can also cause the pool tiles or liner to pit. If you are noticing corrosion or pitting—or want to prevent it from happening in the first place—test the pH and alkalinity levels in your inground or above-ground pool.
If the pH is below 7.2 and the alkalinity is below 110 ppm, add baking soda to the water. It will work as a pH and alkalinity increaser to bring the levels closer to where they need to be to avoid corrosion.

3. Baking soda minimizes scale and algae buildup in a swimming pool.Algae and scale buildup can cause the pool walls to feel slimy and the floor to feel slippery. They also can give the water an unattractive green tint. Begin by killing the algae with an algicide. Then, superchlorinate—or shock—the water and allow it to circulate for up to 10 hours to clear the pool.

Once the water has cleared, test the pH and alkalinity levels of the water.
Add enough sodium bicarbonate pH adjuster to raise these levels to the ideal range (between 7.2 and 7.8 for pH and at least 100 ppm for alkalinity). If needed, you can also sprinkle a little baking soda on slimy tiles and use a scrub brush to remove any stubborn algae.

How to Use Baking Soda in a PoolUsing baking soda in a pool can be an important part of your pool maintenance routine. The step-by-step directions below can help you learn how to use this important pool maintenance product.
- Test to determine the pH and alkalinity levels of the water. Baking soda can be used if the pH is lower than 7.2 and the alkalinity if below 100 ppm (or especially if it is below 80 ppm).
- Determine the appropriate amount of baking soda to add to the water. How much baking soda to add to a pool can vary. A total of 1½ pounds of baking soda typically increases the alkalinity of a pool holding 10,000 gallons of water by 10 ppm.
You’ll need to take into account the size of your pool and the current alkalinity reading to determine how much to add. Start with less than you think you need, since adding more will be easier than raising the pH too much and needing to add an acid to lower it again. - Sprinkle the appropriate amount of baking soda over a large area. Do not simply dump it all in one section, since it may clump. You should also avoid sprinkling the baking soda on a day with a lot of wind; the wind could blow it away before it makes it into the water.
- Allow the baking soda to circulate in the pool for at least 6 hours. Be sure to turn on the pool’s pump to help it circulate more thoroughly.
- Test the pH and alkalinity levels again. Repeat the steps above if levels are still too low.

Alternatives to Baking Soda for Pool MaintenanceBaking soda can be very handy for pool maintenance, but it is not the only option for how to increase alkalinity in a pool or raise the pH level.
Soda ash, or sodium carbonate, also works to increase alkalinity and raise pH in a pool. However, soda ash doesn’t impact the alkalinity as much as baking soda does. It can be a better alternative if your alkalinity parts per million is already at the right level, and you just need to raise the pH.
Having both soda ash and baking soda on hand is a good idea. If just the pH needs to be raised, add the soda ash. If the pH and alkalinity are too low, opt for the baking soda.

- What problems can low PH cause?
- How to increase the rate? 0.5 kg0006
- HTH pH-Plus 1.2 kg
- Equi-Plus powder
When should I increase the level?
According to GOST R 53491.
1-2009, normal pH value for a pool is 7.2-7.6. If the indicator falls below 7, then it must be urgently raised. The same document advises the use of caustic soda (caustic soda), sodium carbonate and preparations based on them for this. nine0003
What problems can low PH cause?
If the pH is low, the pool will be acidic. Hydrogen cations appear, which oxidize the surrounding substances.
This causes a number of problems:
- metal parts in the pool begin to rust;
- equipment deteriorates;
- grout breaks between tiles;
- the skin of people who have taken a dip in the pool turns red and itches.
In addition, some disinfectants work best at a neutral or slightly alkaline pH. Therefore, before making them, always check the level of acidity. nine0003
How to increase the rate?
Before using any product, it is necessary to determine the acidity of in the pool. Testing is carried out at least once a week.
Calculate the required dose and apply according to the instructions for the drug.
In large pools, dosing systems (automatic devices) are used that regularly monitor the pH and add the drug in the right amount. In small reservoirs, the procedure is carried out manually.
Liquid preparations
Preparations in liquid form are usually solutions of alkali of a certain concentration . They are packed in canisters and plastic bottles. Apply at automatic dosing stations, or manually, after diluting.
Markopul Equi-plus
The drug is a 25% solution of inorganic alkali, it is produced in Russia, 30 liters costs at least 1900 rubles.
For manual application:
- Wear gloves for safety. nine0006
- Dilute the product with water in a separate container, reducing the concentration by 3-5 times (per 100 ml of the product 200-400 ml of water, and the drug is poured into water, and not vice versa).
- Pour the solution near the water supply. To increase the pH by 0.1 position, add 125 ml per 10 m3.
The drug should be applied gradually, controlling the level of acidity. The solution should not come into contact with skin and metal surfaces.
Neochimax Neo-Plus Zh
Means of the “pH plus liquid” category, Russian production. A 20 liter can costs about 900 rub.
If you need to add Neo-Plus manually, then do the following:
- dilute with water in a plastic bucket, reducing the concentration by 3-5 times;
- add the resulting solution to the place where the water is pumped at the rate of 100 g of the substance per 1 m3 of water to raise the pH by 0.1;
- take a technical break of at least 3 hours.
You can pour the solution evenly around the perimeter, stirring the water. Work with the drug in goggles and gloves. nine0003
Aqualeon pH-plus
Another product made in Russia.
A 30 l canister is sold at a price of approximately 1800 rubles. It is an aqueous solution of alkali with active additives.
In manual mode Aqualeon acidity regulator is used as follows:
- Diluted in a separate bucket, lowering the concentration by 5-10 times (400-900 ml of water + 100 ml of the drug).
- The resulting solution is added to the pool in small portions. Dosage: 125 mg per 1 m3 to increase the pH by 0.1. nine0006
For example, for a pool of 10 m3 and raising the pH from 6.7 to 7, it will be necessary to pour 3 liters of 750 ml of the prepared solution. Read more about Aqualeon chemistry here.
Powder products
Products are small granules similar to powder. There are quite a few manufacturers, both Russian and foreign. The packaging is also different. You can purchase a small package or a whole bucket of several kilograms.
Bayrol pH-Plus, 0.5 kg
This is a German trade mark.
Packing 0.5 kg costs about 230 rubles. It is a concentrated powder consisting of bicarbonate and sodium carbonate.
Directions for use: 100 g of granules are added per 10 m3 to increase the value by 0.1. Pour into the place of water supply or at several points along the perimeter. Do not add product before the filter. Read more about Bayrol chemistry here.
HTH pH-Plus 1.2 kg
Packing powder weighing 1.2 kg costs about 1000 rubles. nine0051 Instructions for use:
- determine the required amount of the substance, at the rate of 150 g per 10 m3 to increase the pH by 0.2;
- dilute the powder in a separate container with a small amount of water;
- is poured in at the points of water outlet into the pool.
Granules dissolve quickly, do not form sediment and foam. They can be placed in the distribution tank of the dosing pump (1 kg per 10 l). Read more about the chemistry of HTH here.
Equi-Plus powder
A package of 0.5 kg will cost 130 rubles. The powder consists of 95% sodium carbonate. Code of Use:
- Take granules at the rate of 100 g per 10 m3 to raise the pH by 0.1.
- Diluted in a separate bowl and added in small portions to the pool.
Do not mix with other chemicals. Handle with care, avoid contact with skin, mucous membranes. The packaging shows a table that shows the approximate dosage for different volumes of pools. nine0003
Soda
Many pH booster powders contain sodium carbonate. It's soda ash. Therefore, sometimes it is used directly.
Step-by-step instructions:
- for 6 m3 you will need about 90 g of soda ash, for 12 m3 - 180 g - this is the amount to increase the indicator by 0.1;
- the substance is added to the skimmer or poured from the deeper side;
- is applied in small portions.
Baking soda (sodium bicarbonate) is sometimes used instead of soda ash.
It must be added more, since when dissolved in water, it gives a slightly alkaline reaction.
Why can PH drop and how can it be prevented?
There are several reasons why the pH level drops:
- The pool is washed with acid products.
- Add water that does not meet the standards.
- The reading level of a pH meter is affected by temperature. The higher it is, the lower the pH value. nine0006
- The pH at the surface of the water can remove carbon dioxide from the atmosphere.
To keep the indicator always at an acceptable level, it is necessary to periodically measure it and add PH-boosting agents.

Conclusion
Liquid and powder products, which include alkalis, are used to increase the pH level.
Drugs are applied manually or with a dosing pump. You can use soda ash, following the dosage rules. nine0003
Permissible index value in the range 7-7.6 . High acidity of the water (low pH level) leads to deterioration of the pool material and negatively affects the skin.

12 AMAZING PROPERTIES OF BADDING SODA
Everyone remembers it from childhood. Our grandmothers and mothers also used it to clean sinks and bake pies. But today there is a huge variety of all highly effective means. So why go back to banal soda? Because it is very cheap, efficient and environmentally friendly. It can be used for more than just cleaning. Baking soda will help you do things you didn't know about before. nine0003
1. Baking soda will easily eliminate any odors. For example, in the freezer and refrigerator, trash can, shoe cabinet, car and cat litter box.
To prevent the appearance of an unpleasant odor, you just need to spray a solution of soda in these places.
2. Baking soda is used as an antacid, that is, it effectively reduces the acidity of the stomach. If heartburn occurs, stir a teaspoon of baking soda in a glass of water. Only here it is often not recommended to use soda for this purpose. nine0003
3. Baking soda is a great substitute for expensive bath salts. Such a bath will have a strong anti-inflammatory effect. If you are tired and the state of your nervous system leaves much to be desired, then just pour a few tablespoons of soda into water and add a little of your favorite essential oil. The beneficial effect will not keep you waiting. After taking such a bath, you will feel the softness and smoothness of your skin and pleasant relaxation.
4. Soda can be used to clean almost all surfaces: stainless steel, sinks, bathtubs, tiles and chrome. It is very efficient and completely environmentally friendly. It can even whiten your teeth, that is, remove deeply ingrained plaque from them from tea, coffee and cigarettes.
nine0003
5. Baking soda is excellent for cleaning drains. To do this, pour a glass of soda into the drain, then add a glass of alcohol vinegar, leave for 5 minutes and rinse with water.
6. You can also use baking soda to care for your pet. If there is simply no time to bathe the animal, then spray a solution of soda on the coat, and then comb it. Wool after such a procedure will cease to stink like a dog, become smooth, and will look clean.
7. You can add a glass of soda when washing. It enhances the action of washing powder, softens water and helps to preserve the color of things or the whiteness of linen. It works just as well as well-known brands. So why spend extra money? nine0003
