How To Increase Ph In The Pool

How to raise ph to your swimming pool

There are any number of commercial chemical products that you can use to raise the pH of your pool. Usually they have brand names that involve the word pH Increaser, Up, or Raise.

We recommend this pH increaser here.

Whatever their trade name, all these products are based on sodium carbonate otherwise known as soda ash. Be aware, though: sodium carbonate isnt the same thing as sodium bicarbonate, AKA baking soda.

Yes, you can use baking soda to raise the pH in pool, but its not ideal. See below.

  • Make sure that the pump and filter system is running.
  • Test your water in order to determine the current pH and, therefore, how much you need to raise the pH back to the desired 7.4-7.6 range.WORD of WARNING: pool test kits and testing strips typically only measure down to a pH of 6.8. So, if your pool waters pH is showing a reading 6.8, the actual reading may be even lower. What you need to do, first, is to bring the pH back up into the measurable range, and then fine tune from there. We recommend these Water Testing Strips and Liquid Testing Kit here.
  • Calculate how much sodium carbonate you need to add. As a general rule 175 grams of sodium carbonate will raise the pH of an average backyard pool of 32 m2, or approximately 42,000 litres of water, by 0.1.

Grams of Sodium Carbonate Required to Raise pH to 7.4-7.6

pH Reading
340 grams 8.0 grams
  • Retest the water for both pH and total alkalinity after 6-12 hours .

Why The Alkalinity Of Your Pool Is Low

There are different causes to the low level of alkalinity in your pool and you need to examine each to know which is the cause of your pools low level and put an end to it. The following can be the cause of your pools low alkalinity level.

You may want to reduce the alkalinity level of your pool and use too much alkalinity reducer in your pool. This can cause your pools alkalinity level to reduce beyond normal and make the pool harmful.

You may have also backwashed your pool during its usual maintenance period and drained a large part of the pools water. When you add fresh water to the pool without stabilizing the alkalinity level, this can reduce the total alkalinity level of your pool.

Another cause of this can be when your pool has mixed with a local source of water such as rain, flood, or snow that has melted into your pool. Now remember that the local source of water is already low in alkalinity and when it mixes with your pool it reduces the alkalinity level also and as a local source of water can reduce the alkalinity level of your pool, so can any water source with low alkalinity level.

How To Add Liquid Acid

Adding liquids like muriatic and sulfuric acid is a much easier and self-explanatory procedure, but they are also more dangerous. Acid is dangerous to handle, so ALWAYS use safety gear! Glasses and gloves are important, because acid can burn your skin immediately on contact. You can use the Orenda app to figure out the exact dose of muriatic acid you need, in fluid ounces . Note, the Orenda app does not offer dosage for sulfuric acid, so you will need to do that calculation on your own.

You will need:

  • Safety equipment – glasses and gloves
  • The liquid acid of choice
  • A plastic measuring cup for liquids

Step 1

Test your pool water and your fill water for pH and alkalinity. Record results, and if you want, you can put them in the left side of the Orenda app calculator. Set your desired chemistry on the right side, and tap Get Dosage. Bring the liquid acid of choice to the pool with the other items listed above.

Step 2

Dip the bucket into the pool until it is at least halfway full of water. Measure and pour the prescribed amount of acid into the bucket. The objective is to achieve at least a 10:1 dilution ratio. So for half a 5-gallon bucket , you should not exceed one quart of acid of acid. If you need more than the bucket can hold, simply repeat the process as needed, or bring an extra bucket.

How To Raise And Lower Ph In Swimming Pools

pH plays a major role in maintaining swimming pool water balance. It is a measurement of whether your pool water is acidic or alkaline. Several factors can contribute to the pH level of your swimming pool water, including the environment, swimmers, weather, chemical additions, or even water supply.

Low pH, or acidic, conditions can create a corrosive environment that may damage pool equipment and surfaces. It inhibits your sanitizers ability to effectively kill bacteria, which can be harmful to swimmers. It can also lead to skin and eye irritation.

On the other hand, high pH causes your swimming pool water to become too alkaline, which can also reduce your sanitizers effectiveness. If other parameters are improperly balanced, having a high pH can induce scale formation on your pools surfaces or equipment. High pH can also cause skin and eye irritation and may cause cloudy water.

Always maintain pH between 7.2 and 7.6. Start by testing your pool water. Use a pH increaser to raise a low pH level in your pool water. Alternatively, use a pH decreaser to lower a high pH. Split into dosages of thirds, following label directions until pH levels are within the desired range.

Retest your swimming pool water regularly to ensure the pH level remains between 7.2 and 7.6. Use your Clorox® Pool app to test your pool water 2-3 times per week. If you need additional help, Contact Us for advice on maintaining a balanced pool.

Whats The Difference Between Ph And Alkalinity

Some people might be confused between pH and alkalinity. We have shown you the overview of the pH above, and now time for the alkalinity. Alkalinity is used to measure the waters support capacity to hold the change of pH.

If we dont control the alkalinity, the pH will rise and fall abruptly. The alkalinity measurement will be in parts per million or ppm. The ideal ppm for the pool is 80 120 ppm. If we get high alkalinity, it will be hard to adjust the pH. You might need acid to make it low. Moreover, with low alkalinity, it is hard to keep the water balanced. Adding Some baking soda will help it rise.

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.

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.

How To Balance Ph Levels In A Pool

How to raise your swimming pool ph

When it comes to the actual enjoyment of our pool or hot tub/spa, one water balance element is more important than all others: pH.

A pH level that is too high or too low causes skin and eye irritation, affects equipment and pool/hot tub/spa surfaces, and has an impact on the effectiveness of sanitizers.

So what is pH?

pH measures how acidic or basic a solution is. The pH scale goes from 0 to 14 with 7.0 being neutral. Anything below 7.0 is considered acidic and everything above 7.0 is considered basic.

Here’s how that relates to pools and hot tubs/spas:

7.4 – 7.6 7.2 – 7.8

Everything has a pH. Coffee has a pH of 5.0. Most hand soaps have a pH of 9.0-10. The fluid in your eye has a pH of 7.4. Lemon juice, on the other hand, has a pH of 2.4. If you’ve ever squirted lemon juice in your eye you know it burns. It burns because the pH of lemon juice is well below 7.0, which makes it very acidic. So the reason why your eyes sometimes burn during or after you swim in your pool is because the pH level in your pool is below the acceptable range.

The lower on the scale your pool pH levels are, the more acidic and corrosive your water becomes. The higher on the scale your pool pH levels are, the more basic and alkaline your water becomes, leading to scale formation.

So the goal is to keep the pH as close to the ideal range as possible to help ensure proper water balance. The basics include:

Continue to add appropriate product until your water has a pH level of 7.2-7.8 .

Test Ph And Pool Alkalinity

After we add the product and wait about 6 hours for it to disperse and dissolve in your swimming pool, its time to start testing. We will have a testing kit for both total alkalinity and pH.

WE will begin to take readings after 6 hours, then 24 hours, then 48 hours to gauge if there are any small changes over this period and to ensure the chemicals are balanced. We will make sure that both the total alkalinity and pH values are within optimal ranges.

Can I Use Baking Soda To Raise The Ph

Yes you can. But there are a couple of drawbacks.

  • Baking soda is only about half as efficient at raising pH.
  • Baking soda not only raises the pH, it also raises the total alkalinity. What that means in practice is that you should only use baking soda to raise pH when the total alkalinity is significantly below its desired range of 80-120 ppm. If the total alkalinity is close to or within the 80-120 ppm range, the danger is that baking soda will over-raise the total alkalinity: and then you will suddenly be two chemical levels out of whack instead of just one.

Check The Total Alkalinity Then Add Some Baking Soda

Total alkalinity is used to illustrate the sum of all the waters materials.

If total alkalinity is low, this can bring about random fluctuations in your pH levels. If you find that you still get low pH readings even after youve added soda ash, low total alkalinity could be the underlying issue.

To raise total alkalinity in your pool, you can use sodium bicarbonate baking soda which is quite similar to soda ash. By adding 1.4 pounds of baking soda for every 10,000 gallons of pool water and then allowing it to recirculate, you should find this fixes the problem.

How to balance pool water? Nothing ruins the enjoyment of a swimming pool like dirty or unbalanced pool water. It can be tricky to get the water just right, so follow these tips for perfect swimming pool water.

Start with pH. Inexperienced pool owners often think that all you have to do is shock your swimming pool with chlorine, but the truth is that pH is the key. If your pH is not balanced, any other chemicals that you add will be ineffective. The ideal pH is between 7.4 and 7.6. If your pH level rises even to 8, the chlorine in your pool will only be 20% effective. The higher the pH gets, the less effective the chlorine becomes. Balancing the pH first will save you a lot of money on chlorine because you wont be dumping ineffective chemicals into your swimming pool over and over.

A pH level of 7.8 or above is considered alkali. In addition to not being able to hold chlorine in the water, the water will develop precipitation, meaning that it turns the chemicals into solids. You will see buildup on the sides of the pool, and the water will turn cloudy. The filter will accumulate buildup quickly. To adjust a high pH level, use a pH Reducer such as Muriatic Acid or pH down. Be sure to test again the day after using apH Reducer to make sure you have reached the desired level.

How To Lower Ph In Pool Water

Lowering the pools pH can be done in a number of ways using a variety of pool water products. The first one we recommend is muriatic acid, also known as hydrochloric acid, which is especially useful for larger pools.

Make sure to purchase one that is meant for swimming pools or spas to get the correct concentration level.

Read the instructions carefully, as some muriatic acids are pre-diluted and can be added to the pool directly.

Others may need mixing in a bucket of water before putting it into the pool.

Remember, always mix chemicals into the water, not the other way around, as you want to avoid the concentrated acid getting splashed up if the water is added.

How much you need to add will depend on the size of your pool, as well as its current pH level.

As with all pool chemicals, be sure to wear protective clothing in case of spills.

Another product you can use to decrease the pH of the water is sodium bisulfate, also known as dry acid. This acid has the advantage of being easier to handle than muriatic acid. Follow the instructions carefully as different manufacturers have different instructions.

With both of these products, make sure to add them in front of the return jets and wait 4 hours before anyone gets in to ensure that the acid has circulated evenly throughout the water.

Low Alkaline: What Does That Mean

Just as low pH and low calcium hardness levels can be damaging to your pool, so can having a low total alkalinity level.

While a low alkalinity level may not immediately be noticeable on pool equipment and surfaces, a low alkalinity level will often drive the pH level in the pool down.

Along with the damage to your pool surfaces, low alkalinity will also interfere with the sanitizing activity of chlorine. Without a good disinfectant, your pool will turn into a breeding ground for microorganisms in no time.

Why Raise Pool Alkalinity Levels

It can be very harmful for both your pool and those who swim in it if the water has a low alkalinity. Levels lower than 80 ppm can cause the walls of your pool to crack, delaminate, or become etched. Whereas, metal surfaces will deteriorate and melt when exposed to such corrosive water conditions. Aside from its effects on the pool itself, an acidic swimming pool is unsafe for swimmers and can cause skin, eye, and nasal irritations.

Even the smallest changes in chemical composition in your pool water can cause severe variations in the pH levels. When your pools pH level becomes unbalanced, this phenomenon is referred to as pH bounce and can also result in low alkalinity.

When you have low levels of alkalinity, the traditional amount of chlorine that is added to your pool will have no effect. In fact, youll have to buy significantly more than the usual amount of chlorine to achieve the same results.

What Causes Low Ph Levels

How To Lower pH In Pool | Use Clorox pH Down

Mostly low pH levels come from natural factors like rain. The natural pH of rainwater is about 5. So after a heavy rainstorm, its normal for your pool to have a lower pH. Its a good idea to test and rebalance after each storm.

Low pH can also happen after a large party or just having a ton of people in your pool in a short period of time. The more people in your pool, the lower the pH will go. This is caused by dissolved bodily fluids. Gross, I know.
