Baking Soda In Pool Water Will Save You Money
The best part about all this is that baking soda is often cheaper than an alkalinity increaser. And you can buy baking soda in bulk just like the pool supply store brand.
On top of that, you can always use any extra baking soda to brush your teeth, make a cake, or clean your dishes.
S After Stabilizing Your Pools Alkalinity Levels
Lets face it high school chemistry was a difficult subject for most of us. Pool chemistry is runner up and can be overwhelming to grasp. However, it is essential when owning a pool, so perfecting the sciences is wise. The pool professionals at Shoreline Pools have the experience necessary to balance the alkalinity levels in your pool water. Dial to schedule a meeting with our pool servicing team.
One Has A Very Real Impact On Your Bottom Line
You know youre the only one who buys that, the counter person at my local distributor would say as he headed to the warehouse to pull a 50-pound bag of soda ash.
The industry standard has always been to use sodium bicarbonate to raise total alkalinity and sodium carbonate to raise pH the exception being if both total alkalinity and pH are low. Understanding that it is impossible to raise one without effecting the other chemically, there is still a right tool for the job analogy that comes into play.
Using sodium bicarbonate will have a more measurable effect on total alkalinity, while only raising the pH of water slightly. Sodium carbonate will actually have a dramatic effect on both pH and total alkalinity. Using sodium bicarbonate to raise pH is the equivalent of driving a nail into a wall using the handle of a screw driver it can be done, but a hammer would handle the job more effectively and at much less of a cost.
So, if very few service companies are purchasing soda ash, one can extrapolate that either the pH in swimming pool water is never low, or individuals are using sodium baking soda to adjust pH. In fact, it is the latter that has become common practice, often supported by the argument that sodium carbonate is more likely to cloud the water slightly upon addition. With that, one has to understand that there are both water balance and product cost repercussions involved in making this chemical decision.
Got all that?

Measure And Adjust Calcium Hardness
If you ever notice a while line or scaling around your pools water line, its probably calcium buildup. And how often you see it is directly related to your pools calcium hardness level.
Ideal Calcium Hardness level: 200 400 ppm
How to increase calcium hardness:
To increase your pool waters calcium hardness use calcium chloride. Follow the usage instructions printed on the packaging.
How to decrease calcium hardness
- Partially drain your pool and refill it with fresh water.
- Use a flocculant to collect and vacuum excess calcium.
Sanitizer is what keeps your pool free of germs and bacteria. Without it, every pool would quickly become a breeding ground for germs.
But luckily, we use sanitizers like chlorine to keep the water safe and healthy.
When it comes to measuring chlorine, there are a few numbers to keep track of:
- Free Chlorine
- Measures the amount of unused, or available chlorine in the water
To find your pools combined chlorine : subtract Total Chlorine from Free Chlorine
Ideal levels for chlorine: 3 ppm
Chlorine comes in a few forms:
- Chlorine tablets
- Salt chlorine generator
For this step, you can save time and shock your pool now. This gives you a jump start on refreshing the water and takes care of sanitizing your pool.
A few other pool sanitizers:
Healthy pool bromine levels range from 3 ppm to 5 ppm
Proper levels for biguanide: 30 to 50 ppm

Pool Ph Is Always High
The most common reason for a consistently high pH level in pools is the use of liquid chlorine or a saltwater system as the primary sanitizer. Sodium hydroxide is produced, which has a pH of around 13. New pool plaster or pebble finishes will also raise pH in pools for about a year after installation. If your pool has water features, such as a waterfall or fountain, these will also raise pH levels in your pool .
What Causes Low Ph
Because pH is such an unstable factor, many things can affect it.
But when its low, it is usually caused by things like rainwater or debris getting into your pool.
Total alkalinity is sort of the stabilizing factor for pH, so its important to test this level every time you test your pH levels.
When it is off, pH is almost always off in the same direction as well.

How Much Baking Soda Do I Add To My Pool
As a rule of thumb, use 1.5 pounds of baking soda per 10,000 gallons of pool water. This should raise the alkalinity by about 10ppm . Or you can use the chart below.
If youre not sure how much water your pool holds, check out our pool calculator.
Once you know your pools volume, and youve measured out the baking soda, dont add it all at once! If you adjust the alkalinity too much in either direction, it can affect the pH as well.
Note: It doesnt matter which type of baking soda you use. The most popular brand is Arm & Hammer, which is a good choice. Any grocery store brand will do as long as the main and only ingredient is Sodium Bicarbonate.
How To Lower The Alkalinity In Your Pool
In this guide you’re going to learn how to lower the alkalinity in your pool .
To lower the alkalinity in your pool, try using a strong acid like muriatic acid, sodium bisulfate, or sulfuric acid all of which will lower the alkalinity.
If your pool water is a little murky or your pool filters seem to be plugged with calcium deposits, then your pool may be suffering from high alkalinity levels.
In today’s post, you’re going to learn all about water alkalinity, what causes your pool alkalinity to get too high, and how to lower it.

How To Raise Ph In Pool Water
If the pH level is too low, add soda ash, also known as sodium carbonate or pH Up.
We recommend never adding more than 2 lbs or 900g of soda ash per 10,000 gallons of water per treatment.
Starting at the deep end, sprinkle the soda ash over the entire surface of the pool.
Make sure that the pump is circulating to move the water around and then wait at least an hour before testing again.
If the pH is still too low, try adding some more soda ash. Soda ash may make the pool water a little cloudy at first, but it should become clearer after a day or so.
Summary Of Key Points
- Total alkalinity should only be lowered when it causes a significant rise in pH levels, or when it causes calcium scaling through CSI.
- To lower pH and total alkalinity, use a strong acid such as muriatic acid, sulfuric acid, or sodium bisulfate, all of which lower both pH and TA, but at different rates.
- You need to use an accurate water test kit that can give you correct readings. If possible, find software that can help you get exact amounts of dry acid to add into the water.
- This process may take longer than anticipated, depending on how high pH or total alkalinity is and how low you need to bring them down before the aeration process begins. However, you can always use an air compressor or any other aerator to accelerate the process.
- If you have achieved the ideal reading for total alkalinity but the pH is scaling up because the process of aeration has not yet ceased, you can use borate to keep the pH stable. The recommended level for pH is around 7.4 or 7.6.

Calculate The Amount Of Water In Your Pool
You probably know how many gallons of water are in your pool, but if youve just bought a home with a pool or something like that, you may not. If this is the case, you might have to do a little math.
Dont panic, though. Its not too hard to calculate. Just plug your numbers into one of these formulas:
Rectangular or square pools: length x width x depth x 7.5
Round pools: diameter x diameter x depth x 5.9
How To Raise The Calcium Hardness In Your Swimming Pool
Adding calcium chloride is the most common way to increase the hardness of pool water. First, check the hardness of the lime in your pool. Determine how many ppm are in the middle of the ideal calcium hardness range. Calcium chloride is the main chemical used to make swimming pool water hard.

How Do You Lower Calcium Hardness In Pool
- Drain and replace the water. Check your water source before changing the water.
- Use a pool flocculant. If you can’t or don’t want to drain your pool water, try flakes to catch excess calcium.
- Try hydrochloric acid. If drainage and flocculation are not working, hydrochloric acid may be added as a last resort.
Set A Target Value For Total Alkalinity
In the same example above, I set my target value of TA at 100 ppm. It is important to note that both the levels of TA and pH reduce when acid is added. A target value of 80 ppm or 90 ppm should be just fine, but I anticipated that the levels of pH would drop way below 7.0 when I add a strong acid, so my experience told me that 100 ppm was ideal for raising the level of pH later on through aeration.

Summary Of Balancing Ph And Ta
– In any case, you get your TA levels lower than recommended levels that are between 80 and 120ppm but pH level is OK, use alkalinity increaser to raise TA back.
– If you have low pH but the TA level is OK, use borax to raise your pH without raising your TA levels.
– Use muriatic acid to lower both pH and TA when high. Use borax to help you raise pH when TA level is still high and you need to add muriatic acid so that you don’t get your pH lower than 7.0.
– Finally, it’s not possible to have low pH and high TA in the same water, or high pH and low TA in the same water. If you have one of the two situations, something must be wrong with your test kit and you need a better one.
Alkalinity Or Ph: Different Task Different Chemical
Lets clear yet another misconception that stems from pH and alkalinitys buddy system: baking soda is not the same as soda ash .
As we know now, baking soda is used to raise alkalinity, which also slightly raises pH. Soda ash is used to raise pH, which coincidentally also slightly raises alkalinity.
If your pH is low, use soda ash. If your alkalinity is low, use baking soda.
And let that sink in. Unfortunately, many pool owners waste a lot of chemicals and time because they use the two interchangeably.

Should I Use Soda Ash And Baking Soda To Raise Ph
Last month, a close friend of mine who has a plaster pool informed me that he had a huge drift in pH. I came to realize that he was using soda ash to increase the pH whenever it dropped below the recommended level, and baking soda to raise TA. Some parts of the internet recommend this as a quick fix, but don’t do it!
Soda ash and baking soda raises alkalinity to abnormal levels, which in turn also increases the pH to a disproportionate amount. When I checked my friend’s pool, pH was at 8.2 and was scaling up higher day by day. Total alkalinity was reading well over 280 ppm when the recommended values should be between 80 ppm and 120 ppm. Luckily, the calcium level did not scale as expected due to the calcium saturation index â it was within the expected range of 250 ppm. Calcium scaling causes cloudy pool water.
If you have a cloudy swimming pool water or a pool algae breakout, then it is likely caused by high TA and high pH levels and you need to shock the pool to balance everything out again.
How To Lower Alkalinity In Your Pool
- |January 30, 2021
Total alkalinity keeps your pool waters pH level in check by absorbing fluctuations in the water balance. In other words, its a pH buffer.
The ideal range for alkalinity in your swimming pool is between 80 and 120 parts per million, and anything above that will ultimately lead to issues with your water chemistry.
Lets talk about why this happens, why it matters, and how to lower alkalinity in your pool the correct way.

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.
Things To Know About The Average Alkalinity And Ph Of Swimming Pool Water
What determines the purity and the freshness of your pool water is its ph scale. If you dont measure the exact pH and chlorine value, youll never have the ability to estimate the water quality inside the swimming pool. The expression pH suggests that the dimension of how alkaline or acidic is the water.
As a matter of reality, the pH scale ranges from 0 to 14. Where pH 7 is thought of as neutral, water over pH 7 could be considered alkaline .
It could be taken as acidic in character if the pH value of this water is under 7. Thus, it is 7.4, which is thought of as the best pH value. This pH value is equal to that of our eyes and our membranes.

What Causes Rise In Ph And Total Alkalinity In A Swimming Pool
One of the major reasons why pH rises above the recommended level for a swimming pool is high alkalinity.
To avoid high alkalinity, add Alkalinity Increaser slowly by slowly while measuring its level and always ensure that your Total Alkalinity is within the recommended range of 80 – 120ppm because if it goes above 120ppm, your pH will definitely rise high.
The second cause of high pH in a pool is using Calcium Hypochlorite pool shock to sanitize pool water. Cal hypo comes with high pH and Calcium level and will significantly increase pH in pool if you don’t take prior measures to balance your pH.
Also, abnormal rise in TA might be caused by the water source. It could be possible that your pool fillwater is already high in alkalinity and will therefore increase your TA once it mixes with more Alkalinity Increaser you are using. Test your water source for alkalinity and use a different source if it has high TA because you’ll need to use too much dry acid more often to lower both pH and TA in your swimming pool.
Getting a perfect balance of pH and alkalinity is a little tricky since acid will lower both but not at the same rate. If you have high pH and TA in your pool, here is the easiest way to lower and balance pH and TA in your pool without using any extra equipment like aerator.
Why Is It Paramount To Raise Your Pools Alkalinity Level
Your swimming pool can come to immeasurable harm if it contains water with low alkalinity. You risk your pool walls becoming etched, delaminated, or cracked. Some metal surfaces will give way and melt under the corrosive water, which aftereffect is a stained pool wall.
Even the slightest alterations on pool water chemical composition can cause severe fluctuations in the pH levels. When the pH level becomes unbalanced, the phenomenon is called pH bounce and can cause low alkalinity in the pool, as the case may be.
With low alkalinity, the standard amount of chlorine added to your pool would be useless. It would only be useful when more than the usual amount is added for standard results. This means you buy more chlorine and waste more time trying to get to an adequate concentration level with the substance. Asides its effects on your pool, a low alkalinity swimming pool is unsafe for swimmers as the acidic water can cause nasal, eye, and skin irritations.
