How Do You Lower pH in Swimming Pool?

The swimming pool is a blue oasis of relaxation and comfort on your property. People dive in to enjoy tranquillity and blissful swims. To keep a swimming pool clean and hygienic and maintain the overall health aspect, you have to keep the pH levels balanced. The alkalinity of the pool is essential and should be handled by professionals so it doesn’t become imbalanced and lead to health problems.

Imbalanced pH levels can affect health and pool infrastructure

The pH levels in a swimming pool are affected most commonly by rainfall, added chemicals, water temperature, municipal/well water quality, weather conditions, hardness of water, filtration system, and number of people using it. People with respiratory issues and sensitive skin have to be very careful if the pH level in the swimming pool is imbalanced as untreated waters can seriously affect their health.

A gentle adjustment of the pH value through a pool phosphate treatment, is imperative to maintain the water’s quality. After all, it would be best to delve deep into the refreshing waters with no fear of the painful swimmer’s eyes or any nasty skin rashes.

High and low pH effect on the pool

High pH

• Water becomes cloudy, affecting the swimmer’s visibility underwater
• Infrastructure can be damaged and filtration systems get ruined
• Growth of microbes because chlorine becomes ineffective
• The vinyl liner of the pool gets damaged
• Rashes on the skin
• Brittle hair
• Dry and itchy skin
• Strain on the pump because of poor circulation caused by mineral scaling

Low pH

• Dimpling and damage to the plaster finishes in the pool
• Irritated mucous membranes for swimmers
• Red and irritable eyes
• Damaged mechanical systems
• Corroded pumps
• Rusted/corroded diving board and ladders
• Chlorine instability
• Overuse of chlorine for cleaning purposes

Process of balancing pH levels

The water chemistry has to be tested thoroughly for imbalanced pH levels with the help of liquids, pool test strips and digital test kits. The instructions on the kits need to be followed and the reagent is added to the collected water to analyze its reaction. Get the pH levels checked on a daily basis by a reliable pool service in Palm Beach Gardens, and make the necessary chemical additions to make sure pH stays within the recommended range and the pool is declared safe.

The color of the water changes and it can be examined using the color chart to check the presence of the chemical. It’s important to test and treat the swimming pool water for imbalances before you end up paying large amounts for repairs. We have expert pool leak detection services to check the pool for leaks.


1. Pool harmony can be attained to a great extent with the help of naturally existing calcium carbonate. This element, when added to the water, acts as a buffer with magnesium and helps balance pH levels to protect the swimmers from pool dangers.
2. To lower the alkalinity in the pool water, our professional pool services use sodium bisulphate or muriatic acid to balance the pool waters. The process involves introducing the acid in small quantities very slowly and constantly checking the pH value so that the changes can be monitored closely.
3. Sulphuric acid magically transforms the water and balances the pH levels. However, the acid has to be added slowly and precisely so that its properties can balance the erratic pH value and make the water safe for use. The pH levels also affect the health of the tiles and the flooring. To remove the watermark stains on the flooring and tiles, Finn’s Pool Services offers excellent pool stain removal services for its clients.


Sodium carbonate and sodium bicarbonate:

If the pH level is more than 7.8, add sodium bisulphate or muriatic acid. If it’s less than 7.2, add soda ash or baking soda. Soda ash or sodium carbonate raises the pH levels very fast and has to be administered with caution. On the other hand, baking soda or sodium bicarbonate has a subtle but effective influence.

Sodium carbonate and sodium bicarbonate can be added slowly and dissolved in the pool water to adjust its pH value. Try to maintain the water pH in the range of 7.3 to 7.6. The amount of chemicals added depends on the levels and size of the pool.

Budget-friendly alternatives are a preference for many and we offer the best pool acid wash service at Finn’s Pool services. We believe in harmonizing the imbalance in the water in a cost-effective manner. Shimmering clean and safe waters is our focus, and we believe in offering this comfort to our clients.
