There are 309,000 public swimming pools in the US. These pools are frequented by various people, especially during hot seasons. Unfortunately, overcrowding causes the pools’ pH level to change, leading to swimmers’ discomfort and bacterial growth.

      This blog will explore the importance of balanced pH in public pools and how to lower pH levels for your pool.


      Understanding pH Levels in Swimming Pools

      pH, which stands for “potential of hydrogen,” is a measure of the acidity or alkalinity of a substance. The pH scale ranges from 0 to 14, with 7 being neutral. The ideal pH range for public swimming pools is between 7.4 and 7.6. Maintaining pH within this range is crucial for several reasons:


      Comfort and Safety: Swimmers are sensitive to water quality. A pH outside the recommended range can lead to skin and eye irritation, making it unpleasant for pool-goers.

      Sanitization: Proper pH levels are essential for the effectiveness of chlorine or other sanitizing agents. High pH can reduce the sanitizing power of these chemicals.

      Equipment Protection: Maintaining the proper pH helps extend the lifespan of pool equipment, including pumps, filters, and pipes. High pH can lead to scaling and corrosion.

      Balancing pH in Public Pools

      Lowering the pH in a public swimming pool can be a bit more challenging than in a residential pool due to the larger volume of water and the number of swimmers. Here’s a step-by-step guide on how to lower the pH effectively:


      Step 1: Gather Your Supplies

      Before you start adjusting the pH, gather the following supplies:

      • pH testing equipment (strips, liquid test kit, or digital meter)
      • pH decreaser (commonly chlorine or sodium bisulfate)
      • Safety equipment (gloves and eye protection)
      • Pool brush and skimmer


      Step 2: Calculate the Amount Needed

      Determine how much pH decrease you need by referring to the product’s instructions. Always follow these guidelines to prevent over-adjusting the pH. Over-adjustment can lead to a whole new set of problems.


      Step 3: Dilution Matters

      Dilute the pH decrease in a bucket of water before adding it to the pool. Pouring it directly into the pool can damage pool surfaces and equipment. Follow the manufacturer’s instructions for dilution.


      Step 4: Safety First

      Safety is paramount when working with pool chemicals. Always wear gloves and eye protection when handling pH decreasers or other pool chemicals.


      Step 5: Slow and Steady

      Slowly pour the diluted pH decreaser into the pool, distributing it evenly across the water surface. Allow the water to circulate for a few hours to ensure proper distribution.


      Step 6: Retest and Repeat If Necessary

      After a few hours, retest the pH levels. If the pH remains too high, repeat the process, waiting at least four hours before retesting after each adjustment.


      Step 7: Monitor and Maintain

      Regularly monitor the pool’s pH levels and make adjustments as needed. Public pools can experience pH fluctuations more frequently, so staying vigilant is crucial for maintaining water quality.


      Preventive Measures for Public Pools

      Maintaining the ideal pH in public swimming pools isn’t just about reacting to issues but also preventing them. Here are some preventive measures to consider:

      Shower Before Swimming: Encourage swimmers to shower before entering the pool to reduce the introduction of contaminants like sunscreen and body oils.

      Use Pool Covers: Using pool covers when the pool is not in use can help reduce the evaporation of water and the loss of chemicals, making it easier to maintain pH levels.

      Proper Filtration: Ensure that your pool’s filtration system works well. A well-maintained filter will remove impurities, reducing the load on chemicals.

      Professional Maintenance: Regularly schedule professional pool maintenance to check for any issues affecting pH levels, such as leaks or equipment malfunctions.

      Educate Staff and Swimmers: Train your staff on proper pool maintenance and educate swimmers about the importance of following pool rules and guidelines.
