What Is Pool Alkalinity

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

Alkalinity or total alkalinity is the concentration of dissolved hydroxides, cyanurates, bicarbonates, and carbonates in your swimming pool. These are alkaline substances that measure at least seven on a pH scale.

You can measure your pools alkalinity using most of the pool testing kits on the market today in parts per million . PPM is equal to a milligram per liter of water.

Some experts talk of pool alkalinity, and that should not get you worried as it means the same as TA. Pool alkalinity relates specifically to a swimming pool water.

pH is the term used to refer to the degree of activity of an acid or base in the water. It is the most important chemical factor to be maintained in swimming pools. pH is measured on a scale from O to 14 with 7 being neutral. Pool water pH is best when kept in the range of 7.2 to 7.8.

A value of 7 to 14 is considered basic with 14 being the greatest base activity. Another word for basic is alkaline however, this is not to be confused with total alkalinity. pH and total alkalinity are not the same but can be influenced by each other.

A pH value between 0 and 7 is considered acidic with 0 being the greatest acid activity and getting weaker as it approaches a value of 7. When pH remains below 7.2, the water is considered to be corrosive. This means etching of plaster and metals in equipment such as heat exchangers will result. In addition, it is more difficult to keep chlorine in the pool because while more effective as a sanitizer at the low pH, chlorine is also much less stable resulting in the consumption of larger quantities of chlorine than would be used at normal pH levels.

How To Use Baking Soda To Spot

It is common to find some form of black or brown spots around the pool sometimes. These black and brown spots are a result of algae. However, there is no need for you to panic as I will show you how to spot-treat algae problems in a pool.

Step 1: Visit your grocery store, purchase any algae killing product, and proceed to add it into your pool by following the manufacturers instructions written on the labeling.

Step 2: Allow the algae to kill the product to circulate. Again, the time taken for this product to distribute is dependent on the size of your pool. However, it may take anywhere between 6 and 10 hours.

Step 3: After proper circulation of the algae killing product, sprinkle your baking soda, allowing it to have direct contact with the problem area.

Step 4: Now, scrub the affected area using a pool brush and watch how the algae disappear.

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.

When the pH level in a swimming pool is low, it means the water is too acidic. A pool with a pH below 7 can exhibit long-term problems relating to acidity such as etching of the plaster and grout used in the construction of the pool, corrosion of pipe fittings and other metal equipment and rapid deterioration of pump O-rings and seals, reveals PoolCalculator.com. An acidic pool also loses chlorine content faster, increasing operating costs. Because the pH of people’s eyes is around 7.2, pools with lower pH will frequently cause stinging eyes and dry, itchy skin for swimmers.

Alternatives To Baking Soda For Raising Ph Levels

Although baking soda is effective and recommended by most for adjusting both PH and alkalinity levels in a pool, there are certain cases where other substances might work best. For example, a pool with the right amount of alkalinity level may possess a slightly lower PH level, in which case using baking soda may not be the ideal option. However, a compound like soda ash, also known as sodium carbonate, will work just fine for the scenario discussed above, in which case adding it in small quantity will only affect the PH, leaving your alkalinity level untouched.

E.g.: To adjust the PH level of a 10,000-gallon pool from 7.2 to 7.6 would require about 21 pounds of baking soda. However, a closer look would indicate that the amount of baking soda mentioned would only so more damage by increasing the level of alkalinity to 150 ppm, more than is required for a healthy and comfortable pool. With the use of soda ash however, it would only take 12.2 ounces of soda ash in 10,000 gallons of the pool to move the PH level of the pool from 7.2 to 7.6. What is more, is that this soda ash process will only add 10ppm or less to the total alkalinity of the pool.

The pH level of baking soda is 8.3, so it takes a lot of it to raise a pools overall pH level. The upside is that using baking soda will never make a pools pH level higher than 8.3 . Still, its better at adjusting the overall alkalinity of the water.

How To Raise Ph And Alkalinity In Pool

When you confirm that your pools alkalinity level is low, you have to raise the standard to avoid harming the pools users or its equipment and walls. Before you begin, you have to ensure that you know the size of your pool and the target range of the alkalinity you want to increase. Most pool maintainers say your alkalinity level should rest between 80-120ppm so always listen to the advice of pool contractors in your area.

To improve your pools alkalinity, ensure you use a product made with Sodium bicarbonate as theyre the key substance to raising alkalinity. To increase the pools alkalinity, follow these steps

Test Alkalinity level: test the alkalinity level of your pool to determine the pools range. If the level is lower than 80 ppm, you need to raise the alkalinity level.

Dilute Sodium Bicarbonate with water: ensure your purchase enough sodium bicarbonate that would get your pool to its desired level. Dilute the mixture if indicate in the product instructions otherwise, you can apply it directly to the pool.

Add Sodium Bicarbonate to the pool: spread the diluted mixture or the powdered mixture in the pool directly and try not to do it in the win to avoid it getting blown away. To ensure that you didnt pour more mixture in one place above the other, pour the mixture in light arching motions.

Allow pool rest: Wait for six hours at least before retesting the pools alkalinity. In all your waiting time, try not to wait longer than 24 hours.

How Much Baking Soda To Add To Pool: And Why

by Pool and Patio Editorial | Apr 8, 2020 | Pool Cleaning Tips |

Having a pool has a way of turning you the owner into a chemist, without you knowing it. With so many tests and measurements needed to ensure the quality and safety of your pool, you will find yourself working almost like a chemist in your free time. With baking soda, however, you can maintain the quality of water in your pool, without having to go through the stress of running so many tests. Baking soda is safe and straightforward to use, while also providing your pool with a clean, clear, sparkling water that is pleasant to swim in. Baking soda does not sting the eyes neither can it cause drying of the skin.

In case you are wondering how baking soda works, and how you can use it to improve the water quality of your pool, just keep on reading as I open you up to the many benefits of this excellent substance.

Factors That Determine The Amount Of Baking Soda To Add

How To Increase Your Pools Alkalinity For Cheap – Just Use Baking Soda!

The factors determining the amount of baking soda to add to the swimming pool are the same ones that determine the pH of the pool and they include the following:

Amount of carbon dioxide in the pool

The amount of carbon dioxide in the pool contributes to acidity or alkalinity. The higher the CO² level is, the more acidic the pool will be.

Carbon dioxide mixes with water to form carbonic acid. When carbon dioxide is released from the water, for example, the acidity reduces with the pH being raised in the process.

Amount of algae in the pool

Algae will consume carbon dioxide from the water which will result in higher pH levels. The amount of algae growth is typically measured by monitoring the level of chlorine present and comparing it to a chlorine demand chart specific for pools that contains chloramines, which can be found on any pool supply stores website.

If there are high levels of both organic debris and low concentrations of free available chlorine, then add more baking soda as needed.

Alkalinity adjustment chemicals

The chemicals used to adjust the alkalinity of the swimming pool also affect the pH of the pool. Alkalinity adjustment chemicals like sodium hydroxide and potassium carbonate lower the pH of the water.

For example, AlkaShield is an alkalinity stabilizer that not only adjusts alkalinity levels, but it also helps maintain a stable pH level throughout your swimming season.

Test The Pool Water Again

Wait about an hour and then test your pH and alkalinity again. If theyre back in balance, then your job is done.

But if theyre still off, youll have to repeat the process, adding as much soda ash as you need in order to get it in normal range.

The water will be a little cloudy, but it should clear within a few hours or so.

If youre still having problems getting the pH balanced, you could have other issues that are throwing it off.

Test all the levels to see if there is another problem. Correct chlorine and calcium hardness levels if needed and test the pH again.

Also, make sure your pool is as clean as you can get it, since leaves and debris will cause it to be unbalanced.

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.

Raising Your Pool Ph With Sodium Carbonate

Raise your pool pH with soda ash, also called sodium carbonate.

  • Read the instructions on the label, as different manufacturers might contain different percentages of sodium carbonate, although a container of soda ash should simply be 100% sodium carbonate.
  • Determine how much you need to add, based on your test results. I recommend adding only 3/4 of what is recommended and retest later until you are comfortable with the effect of adding chemicals to your pool. The reason is you want to avoid adding too much and end up having to lower the pH.
  • The instructions might say to dilute the soda ash first. Follow the product instructions for dilution if this is the case.
  • Since this usually comes in a powder, try to avoid doing this in the wind. If applying in the wind is unavoidable, apply the powder downwind from yourself, as you want to avoid getting it on your clothes and skin.
  • Get down as close to the water as you can, as the wind will easily blow the powder into the air instead of your pool.
  • Try to add the powder into your pool at the water return jet sight. This is where the water comes into the pool. Avoid adding the powder where at the water inlet sights, such as the skimmer area. You want to spread the dry acid around in the pool as much as possible, but not into areas that would be pulled directly into the pool pump and filter.
  • The soda ash will dissolve quickly, so there should be little to no need to spread the powder around in the water with a pole brush.

    How to Add Alkalinity Increaser to Pool

    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

    Check Total Alkalinity And Make Appropriate Adjustments

    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.

    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 pools 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 waters alkalinity is too low, any chemicals you add will exponentially affect the pH, creating a condition known as pH bounce. Youll 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 pools 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 youll need pounds of it rather than a pinch.

    How Do You Add Alkalinity Increaser

    Always follow the manufacturer instructions when adding an alkalinity increaser to your pool. They often include:

  • Test your pools TA
  • The first thing is to test your pools TA to determine how acidic your pool is and how much alkalinity to add. If it is below 80 PPM, you will need to add the increaser.

  • Ensure you buy enough alkalinity increaser
  • Ensure that you buy a massive container of sodium bicarbonate to avoid visiting the market soon. Get advice from the retailer by informing him/her about your pools size and TA reading.

  • Read the users instructions
  • Find out how the increaser should be added to your pool. Unless you love chemical, consider adding about ½ or ¾ of the recommended amount.

    You can add more later if the TA level is still low. That removes the need for lowering the alkalinity if the reading goes above 120 PPM.

  • Dilute if necessary
  • Depending on the product you buy, the instructions might require you to dilute the alkalinity increaser before you add it.

  • Add to your pool
  • Sodium bicarbonate often comes in powder form. You can add it to your pool that way but avoid the wind as it can get blown away.

    Spread it into your swimming pool and pour it lightly to prevent excessive powder from entering your pool in one place.

  • Let your pool settle
  • Wait for 6-hour before you retest the TA level no longer than 24-hour.

  • Repeat if necessary
  • Keep on adding the powder until you get a TA level of between 80-120 PPM.

    How To Add Soda Ash Or Sodium Bicarb To A Swimming Pool

    How to use Borax to Raise the pH in your Pool – How much Borax to Add

    Do you need to raise alkalinity or pH in your swimming pool? If so, there are two dry chemicals that you can choose from. One is sodium bicarbonate , and the other is a higher pH substance called soda ash.

    This article will walk you through how to safely and properly add either of these chemicals. And yes, bicarb and soda ash are different! The procedure for adding them, however, is identical. We just dose them differently. Adding dry chemicals like soda ash and sodium bicarb is not as simple as it sounds…you don’t just throw them in the pool. Like any other dry chemical, we should pre-dissolve sodium bicarb or soda ash in a bucket prior to adding to the pool. Let’s explain.
