Are There Any Risks With Putting Baking Soda In Your Pool

How to raise ph to your swimming 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.

Add Some Sodium Carbonate

Sodium carbonate, also known as soda ash, is highly alkaline and dissolves efficiently in water. The other benefit of soda ash is that it leaves almost no trace in the water.

If you add strongly alkaline matter to your pool water, this will raise the pH level, while at the same time reducing the acidity in your pool water.

What counts here is using a light touch. The last thing you want is to go over the top and veer from low pH water to high pH water.

  • Calculate how much soda ash you need making sure not to exceed 2 pounds for each 10,000 gallons of water
  • Check that your pool pump is working. Youll need this to circulate the water
  • Broadcast the soda ash evenly across the surface of the pool water
  • Wait for at least 1 hour. Once the water has recirculated, test the pH levels again

What Lowers Your Pools Ph

Many factors can change your pools pH levels. Some of these are naturally occurring issues, and others are caused by adding too many chemicals.;

Heavy rainfall can lower your pH if your pool is outdoors, especially if your area experiences acid rain. Normal rainwater has a pH of around five, so that can already lower your pools pH. If its acid rain, it can be as low as four.;

If you use your pool a lot, you can cause the pH to get out of whack. The more often you swim, and the more people in the water can lower the pH. If you use your pool more than usual, you may want to test the levels more often.;

Sometimes you can add too many chemicals to your pool mix. This problem happens when someone tries to fix a pool with a too high pH, but it also occurs if the alkalinity is out of balance. Alkalinity is the measure of how well a solution can neutralize an acid.;

You may never figure out what exactly caused the change, but luckily, you dont have to know to fix the problem.;

Check Total Alkalinity And Make Appropriate Adjustments

Relationship Between pH and Total Alkalinity

Total alkalinity is the sum of all basic materials in the water. Low total alkalinity can cause significant and random fluctuations in pH levels. If you are still having trouble with low pH readings after adding the appropriate amount of soda ash, check your total alkalinity.

Sodium Bicarbonate is similar to soda ash and is used in swimming pools to raise the total alkalinity . Add 1.4 pounds of sodium bicarbonate per 10,000 gallons of water and allow the pool to circulate before testing again. Use our total alkalinity calculator to figure out the exact amount.

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.

How Does Baking Soda Work In A Pool

Healthwise, baking soda is used to minimize heartburn, and it does this by neutralizing the acid content of the body. Due to its acid-neutralizing ability, baking soda can also be used in acidic pools to offset the acid content of the pool, such that they become reduced to comfortable neutrality that is not harmful to the skin. An acidic pool is both corrosive and irritating.

Baking soda can work wonders in a pool. Baking soda can:

  • Help to clear cloudy water and restore the sparkle
  • Spot-treat algae
  • Make the pool water softer on your skin.
  • Prevent corrosion and damage to pool equipment
  • Complement the effectiveness of chlorine

The PH of baking soda is 8.3, which means that it is highly alkaline. The bicarbonates contained in a baking soda are both positively and negatively charged. It can attract new ions and form a stable compound that settles outside of the water. The presence of positive and negatively charged ends allows the bicarbonates of baking soda to accept both acidic and alkaline ions, depending on what PH you are trying to achieve. In other words, baking soda can act both as an acid or a base in a solution depending on the environment you are subjecting it to.

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

The Difference Between Ph And Alkalinity

Lots of pool owners get hopelessly confused by the difference between alkalinity and pH. As I already discussed, you measure pH using a scale. On the other hand, you measure total alkalinity in parts per million. This means that total alkalinity is an absolute measure of the concentration of all alkaline substances in a solution.

The most common alkaline substances in a pool are bicarbonate, carbonate, and hydroxides. Alkaline substances are important because of how they affect pH. They act as buffers, preventing pH levels from rising or falling. They do this by neutralizing acids. So, in the end, total alkalinity is a measure of how strongly pool water resists changes in pH levels.

What Are Pool Ph Levels

pH, or potential hydrogen, is how well a solution attracts hydrogen ions. It can tell us how alkaline or acidic a liquid is. You measure pH on a scale from zero to 14. Zero means the solution is acidic, while 14 indicates the solution is basic or containing more OH ions than H + ions.

A neutral solution such as pure water falls in the middle of the scale with a pH of seven. A good level for pool water is a pH of 7.5, which means its slightly basic. Low pH can be caused by:

  • Rainwater
  • Debris such as leaves, bugs, and grass clippings
  • Human secretions such as body oils, sweat, saliva, and urine

How Long Does It Take To Raise Ph In The Pool

The goal of raising the pH in a pool is to restore it to acceptable levels for swimming, and this time will depend on how low the pH has been allowed to drop before being corrected.

To raise the pH in the average-sized pool, will take anywhere around 6 hours to 10 hours. But its important to remember, the more acidic the pool water is, the longer it will take for pH to balance.

If the pH has been allowed to drop below a level of around six, it could take up to 24 hours before reaching an acceptable level.

The time needed for pH balancing will be different depending on how low its dropped and what type of chemicals are being used.

What Happens In A High Ph Swimming Pool

How to Raise pH in Pool: 5 Steps (with Pictures)

A swimming pool with a high pH is considered alkaline, which can cause issues with the pool and swimmers. There can be several answers to what causes high pH in pool, such as a sudden rise in water temperature, but more importantly that the causes are its effects. If the pH level is above 7.8, you can expect the water to become cloudy and to see scaling along the pool sides.

Further, a pH that is above normal prevents the chlorine and other disinfecting chemicals to do their job. This means bacteria and other microorganisms may thrive in your pool. While you cannot see with your naked eye, bacteria in your pool water can be harmful when they enter your body. Read on to learn how to lower pH in pool naturally.

Make Sure Your Pump & Filter Are Running Properly

If pH is the heart of healthy pool water, then the pool pump is the brain. If you’re finding that your pool’s pH level remains consistently low despite your best efforts to raise it, you might need to check on your pool pump and filtration system.

Your pool has an upward climb towards being suitable enough to swim in without a properly functioning pump and filter. It’s definitely worth taking a look to see whether or not there are any issues with them, as they’re an integral part of making sure healthy water and chemicals are circulated throughout your pool.

Low Ph Is Bad For Your Wallet

In addition to expensive damage over time to the pools surfaces and fittings, low pH increases your day to day running costs.

Thats because the effectiveness of both chlorine and the chemicals required to control the pools total alkalinity are greatly reduced by low pH. That means you have to use more of them, thus spending more money.

Why Is The Ph Low

When the tendency of the pool runs toward a low pH, it is usually the consequence of more than one factor. First, water in the pool from municipal water supplies may be naturally acidic. This most commonly occurs in areas where the water is very soft and mineral content is low. Exposure to sunlight also makes chlorinated water more acidic, as does heavy rainfall where the pH of rain is typically low. Aggressive treatment for high alkalinity in the pool by adding excessive amounts of muriatic acid can also result in a low pH pool.

What Does Baking Soda Do For A Pool

How to Raise Your POOL’S ALKALINITY with BAKING SODA | Swim University

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.

Natural Ph Rise: Carbon Dioxide Loss

The chemistry of pH sounds a lot more complicated than it is. In short, the less CO2 in solution, the higher the pH. CO2, when dissolved in water becomes something called carbonic acid .

H2O + CO2 H2CO3

Water + Carbon Dioxide creates Carbonic Acid

See the chart below.

The more carbonic acid in your water, the lower your pH will be. Injecting;CO2 lowers your pH, but not total alkalinity. Acid, on the other hand, lowers both pH and total alkalinity. The opposite is also true about CO2. When;CO2;off-gasses , the amount of carbonic acid decreases; so the pH rises. So aeration itself raises the pH of water because;CO2 escapes.;If you want to raise the pH without adding any chemicals, just aerate the water to release CO2.

Check out this detailed diagram of all the chemistry going on, courtesy of Robert Lowry:

Henry’s Law of Solubility of Gases

Naturally,;CO2;wants to be in about the same concentration in the water as it is in the air. So;CO2 off-gasses until it is in relative equilibrium with the air above the pool. This phenomenon is known as Henry’s Law. And don’t worry, we had no idea what Henry’s Law was either…but it makes a lot of sense as to why carbon dioxide naturally leaves, and the pH rebounds some time after putting acid in. This means chasing pH is a bad habit, because it is futile.;pH is naturally going to rise. Embrace this.

Carbonate Alkalinity

Algae raises the pH of water too

The Two Ways In Which Chlorine Works

Disinfection of water by killing bacteria and algae that cause waterborne diseases. Bacteria in the pool can cause diarrhea to swimmers, ear infections, and skin infections. Chlorine is oxygenated and helps neutralize dirt and debris that enter swimmers water and the surrounding area.

Maintaining the proper pH is essential, as it can affect chlorines effectiveness and eventually lead to unhygienic swimming conditions. Besides, it is also vital for the swimmers safety; the ideal pH for a pool matches the mucous membranes and the human eye pH.

Unbalanced pH can cause itching and irritation of the eyes and skin. Therefore, a pH balance is essential for the health, safety, and comfort of a swimmer. Besides, its also necessary for the longevity of the facility.

Highly acidic water will corrode and lead to the formation of pumps, stairs, and trampolines. Lastly, an imbalance in the levels will also decrease the liner and will require frequent replacement.

Guide To Raise The Ph Level In Your Pool Safely

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
