Baking Soda Vs Soda Ash
Baking Soda isused to raise alkalinity and also slightly raises pH. And Soda Ash is used to raise pH and slightly raises alkalinity.
For example, getting a pH reading around 7.2 to 7.6 in 10,000 gallons of pool water would take roughly 21 pounds of baking soda. This would also increase the Total Alkalinity by roughly 150 ppm . And thats way too much!
But if we wanted to increase the pH of the pool by 0.5, we could use roughly 12 ounces of soda ash. That would only increase the total alkalinity by roughly 8 ppm.
In other words, use baking soda to increase alkalinity and soda ash to increase pH.
How To Add Baking Soda To Your Pool
Add Baking Soda To The Pool
Add baking soda to the swimming pool by sprinkling it evenly from the edges. Do so on a day without strong winds which may instead disperse the baking soda in the air instead of into the pool.
How long to wait after adding baking sodato pool?
After adding the appropriate of baking soda, you need to wait 6 hours so the baking soda can dissolve into the pool water. Add enough baking soda until you reach your desired pH level, and then add salt.
If your swimming pool has a chlorine generator or salt system in place, its best not to add too much sodium bicarbonate as this will affect the chemical balance of both systems over time by generating excessive amounts of either light or heavy chlorines which may result in eye irritation for swimmers and an unpleasant odor.
Once the pooled is balanced with your new pH levels, youll need to shock it again after 20-30 days because pools lose their acidity quicker than they acquire alkalinity due to evaporation through air exposure .
The pools pH should be tested once a week. Add more baking soda and/or salt as needed until you reach your desired level of acidity or alkalinity.
However, pools with chlorine generators should have their pH levels checked every other day so they can regulate the amount of sodium bicarbonate in order to keep it at an optimal range for both safety and maintenance purposes.

Ph And Effective Free Chlorine Table For Salt Water Pools
How important is pH to the effectiveness of chlorine? Heres a table that shows chlorines effectiveness at various pH levels.
So while chlorine would be 97% effective if your pool pH was 6.0, this level is too low because youd experience the negative aspects of low pH as listed above.
Instead, a good pH level of 7.5 means your chlorine is about 49% effective which is the ideal pH range of where youd like to be.
Are There Any Risks With Putting Baking Soda In Your Pool
While theres no risk using baking soda in your pool, there are risks to having high and low alkalinity.
You might notice corrosion in and around your ladders, liner, tiles, or other parts of your pool. This is likely due to low pH and alkalinity for long periods of time.
And if you see scaling or a build-up around your pool equipment, this could be caused by high pH and alkalinity. And it means your water is hard.
All you have to do is keep the alkalinity between 100 and 150 ppm and the pH between 7.4 and 7.6 as often as possible. Test your pool water daily and adjust your chemical levels when needed.

Will Baking Soda Clear Up A Cloudy Pool
Not directly, but it can help. If your water is under-sanitized and causing cloudiness, then you want to make sure your pH and alkalinity are balanced before adding sanitizer.
That said, adding too much baking soda at once can cause your pool water to be cloudy. Usually, you just have to wait for it to fully dissolve, so dont panic. High alkalinity can also cause cloudy water. Check out our guide to fixing cloudy pool water.
Is Baking Soda Really A Good Option For Cleaning Your Pool
While baking soda can clean counters, drains, and even teeth, it will not do much to clean your pool water. A baking soda scrub can brighten furniture, tiles, steps, and grout around your pool, but it cannot replace chlorine or other chemicals that make the water clean.
However, baking soda can stabilize the pH levels in your 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.
can you use baking soda in swimming pools? Baking SodaYou can even use it on your concrete or stone pool deck. This is probably the easiest and least expensive way to clean your pool naturally. Bonus Tip: Baking soda will also increase your pool’s alkalinity, and is far less expensive than most alkalinity increasers. To do this, add 1.5 pounds of baking soda.
Also question is, how do I add baking soda to my pool?
Start by adding 1.25 pounds . Sprinkle the baking soda over the surface, or pour it into a skimmer, using a circular motion that helps it dissolve more quickly. Keep the pool water in motion to avoid cloudiness. Step 5: Allow the baking soda to circulate.
Does baking soda kill algae in pools?
You often find this menacing algae setting down roots in your pool walls, leaving unseemly black dots that can ruin anyone’s pool day. Bicarbonate, the active ingredient in the baking soda, is an effective spot treatment to help to kill the algae and loosen it from the wall. Then, it’s time to start scrubbing!

Effects Of Too Much Baking Soda In Pool
When you add too much baking soda to the swimming pool, the effects include the following:
The pH will be too high
Baking soda is a base and will thus raise pH levels. Baking soda has a pH of 8.3 which is above the recommended level of 7.8 at the maximum pH. pH levels greater than pH of seven can damage the pool paint, tile and equipment.
Parts of the pool will be damaged
If you have a pH that is too high, it will damage the surface of plaster or vinyl pools and make them slippery for swimmers to stand on. The pH will also damage the metal in stainless steel pool components, which can lead to rust and corrosion. Besides that, it will corrode the pools tile and liner.
Reduces the effectiveness of chlorine
A pH of 13 or 14 can also significantly reduce the efficiency of chlorine to disinfect water, which will cause a higher risk for bacteria growth in pools.
Reducing the pH to a safe level will help chlorine become more effective.
Reduces effectiveness of algae control chemicals
Algae are an important part of any swift water ecosystem, but they can also be harmful for humans and animals especially in pools with high levels of cyanobacteria .
The problem is that these microorganisms produce toxins which may cause skin irritation or even lung damage if inhaled. Reducing pool pH will work as a natural algaecide by disrupting their ability to make energy from sunlight.
Alkalinity Increasing Product Vs Baking Soda
Expect to pay $20 for a 16 lbs bucket of commercial alkalinity increaser whereas you can find a 15 lbs bag of Arm & Hammer baking soda for $8. So the package sizes are slightly different but youre paying $1.25 per pound of commercial alkalinity increaser and $0.53 per pound for the baking soda.
Whats the difference between the two?
A commercial bucket of alkalinity increasers ingredient list typically states sodium hydrogen bicarcarbonate as its main ingredient which is the International Union of Pure and Applied Chemistry name for sodium bicarbonate which is also known asbaking soda.
So for the most part an alkalinity increaser is just sodium bicarbonate possibly with an extra ingredient or two either for marketing purposes or for an actual benefit. I checked the safety PDF safety data sheet for one particular alkalinity increaser and it referred to a Trade Secret in the section that specified product composition and ingredients. But the main ingredient is still baking soda.
Having said that, heres a comparison as to how much alkalinity increaser you will typically need to use compared to baking soda to increase alkalinity by 10 ppm for every 10,000 gallons of water.

How To Raise Ph By Using Baking Soda In Water
- Baking soda
- pH strips
The pH scale runs from 0 to 14, with 0 representing acidic solutions like battery acid and 14 representing alkaline solutions like liquid drain cleaner. Baking soda rests around 8.4 on the pH scale, slightly above the neutral mark of 7. The effect of baking soda will be influenced by the current pH of your water–you will not be able to raise the pH above 8.4, but you can raise the pH to a more neutral level if it is below 8.4.
Measure the pH of your existing water. Insert the strip into the water and let it rest for 10 to 30 seconds. The amount of time you need to hold the strip in the water will depend on the brand of the strip; follow the manufacturers instructions if in doubt. Use the chart that came with your pH strips to compare color and determine the pH.
Add baking soda to your pool. If the pH is under 7.2, you will need to add 3 lbs. of baking soda per 10,000 gallons in the pool. If the pH is between 7.5 and 7.2, add 2 lbs. per 10,000 gallons. If the pH is above 7.5 then dont add any.
Raise the pH of your hot tub if the pH falls below 7.2. Add 1/3 cup per 500 gallons per decimal point you need to raise the pH. For example, if you have a hot tub that holds 1,000 gallons of water and has a pH of 7.0, you would need 1-1/3 c. baking soda.
Make your drinking water slightly alkaline. Add 1/4 tsp. of baking soda to 1 gallon of water. Drinking slightly alkaline water is purported to help dieters lose weight.
How To Clear A Cloudy Pool With Baking Soda
Just how does baking soda clear pool water? This is how its added to raise swimming pool water pH and Alkalinity.
Before you add any baking soda to your swimming pool, you also make sure you properly clean your swimming pools filtration system. That will definitely give you a boost as far as eliminating your pools cloudy water problem.
Example: If your pool water alkalinity is 30 parts per million low and you have a 20,000 gallon swimming pool, you will add 8.4 pounds of baking soda to your pool .
You can dilute the baking soda in a bucket of water or just broadcast it over the entire surface of your swimming pool.

What Does Baking Soda Do To A Pool To Help Make Its Water Better
Have you ever jumped into a swimming pool and your eyes immediately started to burn? Most people would then tell their friends that there is too much chlorine in the pool.
Although heavy chlorine does impact how your eyes feel, chances are the pH level is off in the pool and thats whats causing your eyes to sting.
Adding some baking soda to your pool will most likely eliminate that type of eye irritation. This is just one of the many things that baking soda can do to help improve the quality of your swimming pool water.
How Much Baking Soda Should I Use
One of the potential drawbacks of using baking soda instead of a specially-packaged alkalinity increaser is that baking soda doesn’t come with pool use instructions. But don’t let that stop you from using it.
To calculate how much baking soda you should add, first determine the amount of gallons of water in your pool. Then add 1.5 pounds of baking soda for every 10,000 gallons of water to increase the pool’s total alkalinity by 10 ppm.
For example: If your pool holds 20,000 gallons of water and your test kit is showing you a total alkalinity of 50 ppm, you will want to raise your alkalinity a minimum of 30 ppm . Since the pool in this example is 20,000 gallons, every three pounds of baking soda should raise alkalinity roughly 10 ppm, which is only a third of the level you need. This means you will need to add roughly nine pounds of baking soda to a 20,000 gallon pool to raise the alkalinity by 30 ppm and achieve the minimum alkalinity goal of 80 ppm.
Add the baking soda directly to the pool, let it dissolve and give it time to distribute through your pool’s water , test, and add more baking soda if needed.

Baking Soda And Ph Levels
Adding baking soda will also raise your pool’s pH level some, but if your main goal is to raise the pH versus simply raising alkalinity, we recommend using soda ash in lieu of baking soda. Adding six ounces of soda ash to 10,000 gallons of water will raise the pH roughly 0.2, while adding the same amount of baking soda will have a negligible effect on your pH.
Note that soda ash does also raise alkalinity along with pH. That six ounces of soda ash will raise your alkalinity by about 5 ppm, so only use soda ash if you want to raise alkalinity and pH.;
The Relation Of Ph Levels To Chlorine
Everyone knows that chlorine is vital in keeping pool water healthy and safe for swimmers. However, elevated pH levels can decrease chlorines effectiveness, leading to unsanitary swimming conditions.
On the other hand, adding too much chlorine can lower your pools pH balance. This can cause health problems for swimmers, including irritated skin, eyes, and the nasal cavitys mucous membranes. This is because acidic water strips away the bodys natural oils.
When your pool waters alkalinity is too low, any chemicals you add can create a condition known as pH bounce. pH bounce is when the water rapidly cycles between acidic or basic pH levels, making the water unsafe for swimmers. pH bounce means youll have to keep adding more chlorine to achieve the same sanitizing effect.
