A Swimming pool is a beautiful place to cool off, but when its pH balance lowers, it can be a great source of sickness, irritation, and financial strain.

If you previously tested the pH levels of your pool then found out that it’s too low, then you are in the right place.

Here is a guide on how to raise the pH level in your pool to keep it in the perfect range to make your pool a safe place to be.

How to Raise pH in a Pool Using Soda Ash

This is a strongly alkaline material that can easily dissolve in water leaving behind a small amount of trace. However, using soda ash raises the pool’s pH level as well as reducing its acidity. To use it on your pool,

  • Start by calculating the level of soda ash required. Be careful not to use more than two pounds for every 10,000 gallons of water.
  • Next, ensure the water pump is in perfect condition to properly circulate water.
  • After that, spread the soda ash uniformly all over the surface area of your pool.
  • Then allow the pool to distribute water for about an hour before you retest.

 Aerate the Pool to Raise Its pH

After making several attempts to raise the pool’s pH level and failed, try aerating the water. Although this process will take longer than an hour, or even days, it will finally work. You can aerate the water through turning on the water features then point the jets on the surface. Alternatively, add more aeration pipes on top of the jets.

How to Raise pH In a Pool without Raising Alkalinity

Sometimes it’s hard to raise the water pH without raising its alkalinity because acid affects both water alkalinity and the pH. But there is a nice way you can do to make the process successful. Here’s what to do:


  • a proper pool test kit- make sure you use a digital kit as it provides the most accurate readings that you can work with.
  • Muriatic acid-this helps in lowering both the pH and the alkalinity. You can as well raise the pool’s ph. using sodium bisulfate. However, muriatic acid is most preferred.
  • Protectives-when raising your pool’s ph. level, be sure to use things like long sleeves cloth, goggles, gloves, and other protective clothing.
  • Aeration- this isn’t a tool or a chemical but a nice method to boost the pH level while stabilizing the alkalinity.

However, before you start raising your pool’s ph. level without raising its alkalinity, you must have some idea on the target alkalinity and pH levels of the pool. The ph. level of the pool should vary from 7.4 to 7.6, and its TA level should range between 80 to 120 ppm to make it balanced.

  1. Record and Set The Desired Value Of The Alkalinity Level

Begin by taking the alkalinity and the ph. level readings in your pool using a digital test kit. Perhaps you want to get an alkalinity level of 100 ppm. Remember that both alkalinity and pH levels of the pool reduce once you add the acid.

Therefore, an 80-90 ppm target is excellent, but that will drop the ph. Below 7.0, once the acid is added.

  1. Dilute the muriatic acid then add it to the pool

If you have a 20K gallons pool capacity, to get alkalinity of 100ppm, make sure you add approximately two-quart of the muriatic, be sure to spread the acid uniformly on water. And as you do this, the pump must be running.

Once you add the acid, natural aeration will start and your pool’s ph. the level will begin rising. Give this more time to happen to raise the pH level to the recommended state. But this might consume more time.

  1. Now Test The pH And TA (Alkalinity) After 5-6 Hours

If you wish, be checking on the pH and TA changes through performing some simple tests after six hours. When both TA and pH levels hit the recommended range, and then the process is over.

Within this time, you can get readings such as 205 for alkalinity and 7.6 pH once you perform the initial test.

Again do the testing after 24 hours. The TA should be reading 120 ppm, whereas the pH remains lower at 7.1.

  1. Test The Pool After 48 Hours

After 48 hours, the pool’s alkalinity level should have gone down to about 100ppm that is the recommended range. At this time, the pH must be stable at 7.4 that falls within 7.4to 7.6. The pH value of the water in your pool won’t rise past there since its alkalinity has stabilized.

The pH can’t go past that since the alkalinity level has remained stable. You can also make the pool aeration faster with an air compressor and a tube with a few holes. Position the structure inside the pool, and within a short time, the pH will rise without raising the alkalinity.

How to raise the pH In a Pool Using Baking Soda

  • Test Your Pool

Begin by testing the pool’s alkalinity. Generally, the pH of a pool ranges from74 to 7.8, and its alkalinity varies between 110 to 150 ppm (parts per million). Therefore, if your pool has a lower alkalinity level, then you must raise its alkalinity

Next, buy baking soda in large quantities. You will add up to 10 lbs. of baking soda to the pool. But this depends on how low the alkalinity level is in your pool.

  • Decide On The Amount Of Baking Soda To Add

After that, determine the quantity of baking soda to add to the pool. Many pool chemical measurements are packed based on 10,000 water gallons. Therefore, if your pool is smaller or larger, be sure to adjust your math. Usually, a 1.5 lbs. of the chemical on a 10,000 water gallons pool will boost its alkalinity by approximately ten ppm.

When your pool ph. level tests below 7.2, make sure you add up to 4 pounds of baking soda. Perhaps you are new to using pool chemicals, begin by adding either three-fourths or one-half of the required amount. Immediately after adding the retest, be sure to add more of the chemical when the pH is low

  • Now Add The Chemical To Your Pool

Baking soda is packed in powder form, and you can sprinkle it directly on the pool water. Distribute it in wide arcs all over the surface of your pool to get rid of dumping in at once in a single spot. Don’t use it during the windy season as the chemical might be carried away.

  • Wait for 6 hours

Now, wait for about six hours to allow the chemical to dissolve in water. Also, turn on the pool’s circulation system to facilitate a quick disperse. Repeat and retest if you want between 6 and 24hours from the time you added the chemical.

How to Raise pH In a Pool Using Borax

Borax is a chemical extracted from boric acid used in numerous cleaning activities. Furthermore, it’s essential in small-scale gold mine operations and now essential in cleaning and maintaining a pool’s pH balance.

As an advantage, boric acid can be used to prevent algae development making your water soft and clean. Here’s how to raise a pool’s pH using borax:

  • Perform A Ph. Test

Begin by testing your pool to check its acidity level. The recommended range is 7.4 to 7.6. When the pH is lower, then use Borax to increase it.

  • Measure Borax

For every 5,000 water gallons, use about 20 ounces of borax. This assists in raising the pH level to 0.5. But this depends mostly on your pool water chemical content.

  • Add Borax

Allow the pool’s water pump to run to facilitate an easy Borax circulation. After that, add the chemical to the deepest side of your pool then allow it to run for 72 hours.

  • Check pH Levels

After 72 hours, have a look at the ph. levels to confirm whether it’s within the recommended range. When it’s still low, top-up more borax using the same measurements you used initially (or based on the pH level)

Note that when the pH is higher than the recommended range by less than 0.2, you don’t have to worry. It will decrease after some time.
