How To Lower pH Level Of Swimming Pools

The rise in the pH of the swimming pool is the most crucial problem as it can affect the skin’s pH and may damage it. Ideally, the pH range between 7.4 to 7.8 is considered safe for the swimming pool as it doesn’t harm the skin. 

When the pH of the swimming pool gets high, it creates an alkaline condition which may cause several problems to the skin. Hence, it is essential to lower the pH of the swimming pool water.

Thus, to help you maintain the optimum pH of the pool, I’ve listed some of the best ways to lower the pool’s pH level. So, let’s dive in straight. 

What Are the Causes of the High pH in the Swimming Pool?

Lower Pool pH Level

Different ways can cause a sudden spike in the pH level of the swimming pool. The foremost reason for pH increase is the chemicals used to disinfect the swimming pools. The chlorine stabilizer HTH granular can raise the pH level. 

Besides that, sudden rises in the pH level can also be triggered due to the increase in temperature. For example, if the pool is continually exposed to the sunlight and constant heatwave, it may result in a high pH level. 

What are the Effects of Raised pH level in the Pool?

A rise in the pH level can create a lot of effects and problems, which are as follows:

  • High pH level can make chlorine in-effective which in turn promotes the growth of algae and bacteria.
  • Alkaline pH can make water hard, which further results in the formation of scales of calcium deposits. The scale build-up can result in the clogging of the pipes and filters. The clogged pipes can create the problem of motor failure and leakage.
  • It can irritate the eyes and make skin dry.
  • The rise in pH can also result in the cloudy and hazy pool, making it unfit for swimming.

How To Lower Pool pH Level?

Use a pool test kit to measure the pH level of the pool. Once you know that the pH level is high, you can go with this solution to store the pH balance and make it fit for swimming.

1. Sodium Bi-sulfate

By using the Sodium Bi-sulfate, you can achieve the pH balance in the swimming pool. However, before using this chemical, read the instructions and apply the accurate quantity to lower the pH level.

Some manufacturers suggest using 3/4th of the sodium Bi-sulfate in the pool. It comes in the form of powder. So, try to avoid using the chemical during windy conditions as it may blow back your skin.

  • The individual can add powdered chemicals directly into the swimming pool by sitting close to avoid blowback. Make sure to apply the chemical near the water jet return side as it helps to facilitate the powder to spread into the pool equally. 
  • Once you dissolve the Sodium Bi-sulfate powder into the water, it takes around 10-15 minutes to dissolve the powder completely. 
  • You can wait for six to eight hours to check the pH of the swimming pool. 

2. Muriatic Acid

Muriatic acid is another powerful chemical that helps to restore the pH level in the pool. But keep in mind that Muriatic acid is extremely corrosive, so use protective gear such as goggles and gloves while mixing the chemical into the pool. 

In addition to this, make sure to read the entire instruction carefully and measure the quantity of the chemical properly to avoid any hazardous conditions. 

  • Muriatic acid can be mixed into the swimming pool in two ways. First, make sure to turn off the water pump and pour the chemical slowly into the steady stream.
  • Second, give some time to settle the acid at the bottom of the swimming pool. Once it is done, turn on the water pump to mix properly in the pool.
  • The second way is to pour the acid near the return jets and let the water pump do the rest of the work.
  • Once you mix the chemical, give it at least six hours to mix properly into the pool. Then, check the pH level of the pool.

Bottom Line

These are a few tricks that help you to restore the pH level of the pool. Balancing the pool’s pH can help prevent skin damage, eye irritation, and many more. Moreover, pH balance can further help prevent the pipelines’ blockage, which is difficult to clean.
