Making your pool safe to swim requires consistent examination of the chemical level of your pool, such as the pH level of the pool. The pH level of any pool is the measure if the pool’s acidity and alkalinity and if you try to swim in a pool with an unideal level of alkalinity, it may be harmful to your health.

High PH In Pool Safe To Swim?

What is the Ideal pH Level to Swim?

When the pH level is at the ideal number, it helps the chlorine work perfectly and protects the skin and eyes from harsh chemicals. The right pH level of your pool would help the chlorine component protect your eyes and skin from harsh chemicals. The ideal pH level for swimmers is between 7.2 and 7.8, according to the Centre for Disease Control and Prevention. This level coincides with the pH level of most swimmers body, ensuring the water doesn’t cause any problem for them.

Is High pH in Pool Safe to Swim?

When the pH level of your pool is high, it is considered alkaline and can cause a problem for the pool owner as well as the pool. A pH level of above 7.8 would increase the alkalinity level of your pool and cause the pool water to become cloudy. It would also scale along the sides of your pool. A high pH level causes chlorine and other chemicals from adequately functioning, which lets bacteria in your pool survive. 

You may not notice the difference with bacteria in the pool, but if it finds its way into your body, it could become harmful.

Is It Safe to Swim in Pool with Low Alkalinity?

When the alkalinity level of your pool is low, that means your water is lower than 7.0 and highly acidic. You might also get to feel the difference in the pool as you swim. A low pH level in your pool can cause your eyes to burn while swimming underwater or irritate your skin. Just like a high pH level, chlorine and other chemicals do not work correctly when the pH level is low, causing all the dangerous bacteria to live freely. This can cause your pool metal to corrode while wrinkling the vinyl linings of the pool.

What Should Be Done?

To adjust your pH level at this stage would require carefulness as any mistake can throw the pool water off balance. It would be best if you always started at the shallow end when pouring additives into your pool. If the pH level is high, normalize it by adding dry acid to reduce the pH level. The amount you add depends on the pH reading of the pool. If your pH level is low and needs increasing, add sodium bicarbonate which can be easily found in baking soda to raise the level. You should check to see if the pool’s level is stable after two days to know if you need to add more substance to to raise or lower the pH level.


It isn’t safe to swim in a high pH level pool as this can be dangerous to the health and even detrimental to your pool. So always perform a chemical test to know the level of the chemical in the pool before use.

Borax also known Sodium Tetraborate or Sodium Borate or Disodium Tetraborate, has many uses as it does names for a chemical compound.  It is popularly known to be a household cleaning agent used to bleach white shirts. Apart from being a household cleaning agent, it can also serve as the main ingredient in slime. This goes to show that borax is such a versatile chemical with lots of uses. Now Borax can also be used to clean a swimming pool. 

How Much Borax To Raise pH In Pool?

Keeping your swimming pool clean and sparkling is such a stressful process that involves a lot of action such as checking the water level, cleaning out your skimmer, cleaning your filter, vacuuming the bottom of the pool, and balancing the chemistry of the water. While balancing the chemistry of your pool and trying to avoid increasing one level over the other, you can use borax which acts as a useful pH leveler and helps prevent the growth of algae in your pool.  In this article we would reveal how much borax to raise pH level in pool.

Benefit of Using Borax

Adding borax to your pool is an effective way of stabilizing the alkalinity of your pool. It also works as a pH shocker for your swimming pools. Normally, pool owners make use of baking soda and soda ash whenever they want to stabilize the chemistry level. But these chemicals have disadvantages such as while it raises the pH level, they also raise the alkalinity level of the water. When the alkalinity level rises, it destabilizes the pH level which defeats the reason for putting chemicals into your pool. 

Unlike these two chemicals above, Borax stops your pH level from fluctuating while the alkalinity level remains the same. It also stops the growth of algae through proper maintenance of the pH level of the pool which allows the chlorine sanitize the water.

When the borax is dissolved in your water, it doesn’t evaporate; it remains in the water permanently. This makes your pool water sparkling, soft, and ready to swim plus you’ll be using less chlorine which ensures you save money.

How Much Borax to Raise pH Level in Pool

If you want to raise the pH level of your pool, you’ll have to conduct a pH test first to determine the pH level of your pool. If your pool’s pH level is lower than the normal range of 7.2-7.6, you’ll need to raise the pH level. 

Add 20 ounces of Borax to every 5000 gallons of water added to your pool. This calculation is estimated as different chemical factors may require a different quantity of borax for your pool.


Stabilize your pool quickly using the Borax chemical. It is also a good equipment for keeping your pool clear of algae growth and any other form of dirt.
