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 10 parts per million . 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.
Pool Ph Will Not Increase
If it seems like you keep adding pH Increaser or Decreaser, but it only seems to last a day, or maybe seems to have no effect at all high Total Alkalinity levels over 120 ppm may be preventing you from making an effective adjustment. For pools with high alkalinity and high pH levels, add pH Decreaser or other acid, to affect both.
What About Health Risks
We mentioned getting it in your eye if you add it to your pool on a windy day. That hurts like hell. But besides that, sodium bicarbonate is relatively safe.
Sodium bicarbonate has been used for thousands of years. Most notably by Ancient Egyptians who used it to clean their teeth. Just like we do today!
And its Generally Recognized as Safe by the FDA as a direct food additive.
Think of it this way, if its safe enough to use in cakes, then your swimming pool wont be a problem.

Getting an accurate reading of your pool’s chemical composition is extremely difficult, and deciding what to do with that information is no walk in the park either.
That’s why you should rely on pHin‘s readings. The smart water monitoring device tests your water 144x a day to provide you the most accurate reading based on the results.
The benefits don’t stop there – it also goes on to tell you exactly how much of each specific chemical you need to add to your pool water to get it back into a healthy, balanced state.
What Are Ideal Levels Of Chlorine And Ph
The ideal pH of water to maximize chlorines ability to interact and form hypochlorous acid to kill off bacteria is anything less than 5. However, water with a pH of 5 would be very uncomfortable to swim in. It is also important to take into consideration of the corrosive effects water has on the pool surface.
What we really want to know is what is the ideal pH level that will maximize hypochlorous acid, but simultaneously minimize irritation to human skin and corrosion to pool surfaces. The Center for Disease Control has found the answer to be a pH of 7.45 and free chlorine of 3.0 ppm. The easiest way to check your pH and chlorine levels is with test strips. When your free chlorine levels get too low, we recommend using calcium hypochlorite to raise them back up.

If you have a swimming pool at home, youll need a pool testing kit to ensure that the water levels are all properly balanced.
If the water in your pool is too acidic, this will corrode your equipment, and its likely to bring about etching on surface materials. Beyond this, acidic water will irritate your eyes, nose, and skin.
If, on the other hand, your pool water is too alkaline, this can cause scale to develop on the surface as well as all over your pool plumbing gear.
Neither of these scenarios is ideal. Excessive acidity or alkalinity both impact the efficiency of the chlorine in your pool, and resultantly impede the process of disinfection.
When youre checking the pH level in your pool, you should aim for somewhere between 7.2 and 7.8. On the pH scale, 0 is extreme acidity, with 14 representing extreme alkalinity. 7 is neutral, so youre shooting for just the alkaline side of neutral.
Now, before we show you how to raise the pH level in your pool, a few more basics so you can proceed better informed

How To Raise And Lower Ph In Pool
If the pH is low, a pH increaser is added to raise the pH. If the pH is high, pH Down is used. pH Down comes in two forms: liquid acid or dry acid.
Changes in the pH of pool water can be caused by many factors but one of the most significant cause is the sanitizer used. Since the sanitizer is the most frequently added chemical in pools, it can have a powerful impact on pH and overall water quality.
Of the sanitizers typically used in pools, chlorine is the most common. Chlorine comes in a variety of forms and varies widely in pH. For example, most tableted forms of chlorine have a very low pH and will tend to lower pH over time, while liquid chlorine is very high in pH and will tend to raise pH values. Salt is also very alkaline and will require frequent additions of acid to maintain the proper pH and overall water balance.
Changes in pH due to sanitizers or other factors can be minimized and controlled by the proper maintenance of the next chemical factor, total alkalinity.

Manage The Chlorine And Your Ph
Chlorine kills bacteria, helps prevent algae growth and destroys other organic matter in the water, so maintaining proper chlorine levels is key to making the water safe to swim in.But before chlorine can do its job, your waters pH has to be stabilized. If the pH is too high, chlorine becomes inactive. Too low, and chlorine becomes unstable and could evaporate reducing its effectiveness.
Once your water pH and your alkalinity are balanced, its time to chlorinate.
- Chlorinate your pool in the evening to allow the maximum length of time for the disinfectant to take effect; strong sunlight can actually deactivate and destroy the chlorine in your pool!
- Shock your pool to block the accumulation of organic waste products. Swimming should be off-limits until chlorine levels return to normal.
- The ideal time to shock your pool is every other Sunday evening, since they follow heavy swim periods, which can alter levels.
Low Ph Is An Easy Fix
Raising the pH level of a swimming pool is as easy as adding more alkaline materials. Soda ash and sodium bicarbonate are two common alkaline products that can be used to raise pH levels in a pool. Remember that optimal pH levels for a swimming pool are between 7.4 7.6! If you overshoot it and need to bring your levels back down, read my guide on how to lower your pool pH level.

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 Total Alkalinity Back Down
Now that you know using something like soda ash to raise the pH can also bring up TA in a big way, you may need to lower it when retesting.
TA can be lowered using either muriatic acid, orsodium bisulfate.
Muriatic acid is more commonly used due to its lower price. However, sodium bisulfate is a dry acid that is more safe for handling, as the former can cause major burns, and its fumes can induce respiratory distress if youre not careful.
Either one will work fine, it just depends on your budget and how comfortable you are working with acid.

What Is Borax In
Borax, otherwise known as sodium borate, sodium tetraborate, or disodium tetraborate, is a white chemical like powder made from the mineral of boric and boron acids commonly seen in an area with occasional lakes. For the vast majority, borax is a household item that is most useful for making the swimming pool water look astonishingly sparkle for optimum comfort of the swimmers. The contained boron prevents the growth of algae, and its synthetic properties help to balance out pH at an attractive level while permitting you to utilize less chlorine. Not withstanding, you can likewise use it to enhance the pH in your swimming pool.

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.;
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.

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.

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

Why Ph Balance Is Important
Maintaining the correct pH balance not only keeps your swimming pool sparkling clean but also helps preserve your pool finishs aesthetic appeal by preventing it from getting stained. pH balance is also essential to ensuring the longevity of your pool and its components.
Pools need to have a pH level of between 7.2 and 7.8. Pool water with pH levels that are low is acidic. This kind of water is corrosive and can lead to pumps and other equipment breaking down. Basically, everything that acidic water touches gets worn away, including accessories, plumbing, and other parts of the pool system.
Unbalanced pH levels can also wear down pool liners and ladders, causing them to become brittle and crack. Improper pH levels can even strip the copper right out of heat exchangers.
What Causes Low Ph Levels
Before we learn how to maintain correct pH levels in pools, its right, we know first the leading cause of the problem. Low pH levels cause many problems including, premature mortar erosion as well as eroding the pool facility.
Low pH makes the pool floor brittle and cracking. It also causes discomfort to swimmers since they lead to the development of body sensations like, for instance, burning eyes and itchy skin.
In most cases, low pH levels Yare caused by natural factors, including storms, heavy rains, abuse, and chemicals improper use. Rainwater has a pH of 5 5.5; it is, therefore, acidic. Large amounts of rain can make the pool waters pH more acidic; the pH level can drop after a big party.
Solved body fluids can reduce pH levels, so if you have had many swimmers in a pool lately, the facilitys excessive use can be the cause. All market additives that try to control the pH level can cause more harm than good; its even recommended you create a water solution to treat your pools imbalance pH.

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.;
Use Aeration To Raise Pool Ph
If you have high alkalinity and low pH, and are having trouble raising your pH level, how do you lower high alkalinity without affecting pH? You cant, but you can raise pH without affecting Alkalinity. This is done by lowering the pH and Alkalinity with pH Decreaser, then raise the pH through aeration. Just add air!
Aerating pool water works like this: the carbon dioxide in the introduced air bubbles forms carbonic acid as it mingles with your pool water, which raises pH levels.
You can aerate a pool by bubbling air through the water, agitating the surface, or spraying droplets through the air with a pool fountain, which also can be used to lower pool water temperature.
Five Ways to Aerate a Pool to Raise pH
- Air compressor or Cyclone blower with long hose and weighted air diffuser.
- Waterfalls, spillways, wall return and floating Pool Fountains.
- Pointing return eyeballs up to create surface turbulence.
- Install a spa blower onto your pool return line.
- Install a venturi tee air inlet on the return pipe, or into a wall return.
