Is it safe to swim in a pool with low pH?

Have you noticed that your pool’s pH has been a tad on the lower side? You may not see this as an important issue and feel that swimming in water with a low pH is safe. As a pool owner, you will have to be diligent to ensure that your pool is properly maintained. Due to all of the work and knowledge that goes into keeping a pool balanced and safe, you may require the assistance of professional pool service. This article will outline some of the potential health and safety risks of swimming in low pH pools.


When pools are too acidic, with a pH lower than 7.0, cleaning agents may be inhibited from functioning correctly. This can allow microbes to propagate rapidly, which can make swimmers ill. Over the past decade, one-third of all waterborne illnesses in America have come from unsanitary swimming pools and other forms of water-based recreation. Pools can be a breeding ground for a multitude of microorganisms, as pool-goers will often leave trace amounts of dead skin, urine, feces, mucus, and other bits of potentially diseased detritus. Other causes can be contamination from rainwater, as well as plant and animal waste.

Skin damage:

Pool water with a low pH can cause the skin to become dry and irritated. Acidic pool water strips away the oils from the body, cause rashes and itching. Dry skin is vulnerable to cracking, allowing potentially dangerous chemicals and bacteria to flow into the wound.


More acidic water can cause the hair and scalp to become damaged. This can result in hair loss and burns to the scalp. Though these injuries tend not to be serious, they can be permanent.

Mucus membranes:

Acidic water can cause the mucous membranes to become irritated. Exposure to these conditions can make the eyes more susceptible to infections, most commonly conjunctivitis. The nasal passages can also become dried out and inflamed. This can be more than just uncomfortable; it can make people sick.

Enamel erosion:

There is evidence that persistently swimming in pools with a low pH can cause dental damage. The acid can cause tooth enamel to erode, leading to the development of dental caries over time.

Cloudy water:

Low pH levels in pool water can eat away at metal and plaster. The erosion of metals and minerals caused by pool water acidity can make the pool cloudy, making it easier to lose track of swimmers. This decreased visibility can be dangerous for swimmers, as it can increase the likelihood of incurring potential injuries and drowning.

Proper pool maintenance and sanitation are necessary if you want to keep your pool water safe and healthy. This means not only regular removing debris but monitoring the chemical composition and pH balance. For all of the reasons mentioned above, it is essential to enlist the services of professional pool service.
