What do the tested levels mean for your pool?

What is Electrical Conductivity (EC) for swimming Pools

Electrical Conductivity (EC) is a crucial parameter for swimming pools as it measures the water's ability to conduct electrical current, directly linked to the pool's total dissolved solids (TDS) and salinity levels. Maintaining the right EC levels is vital for swimmer comfort and equipment longevity. Proper EC ensures water balance and prevents corrosion, scale buildup, or skin and eye irritation. It's an essential component of water quality management, helping pool owners maintain a safe and enjoyable swimming environment.  

  • Freshwater Pools: For conventional freshwater pools, a target EC level is typically in the range of 1,500 to 2,500 microsiemens per centimeter (µS/cm). This range helps maintain water balance and prevent issues such as corrosion and scaling. It's essential to check your pool's specific requirements and adjust as needed based on your pool's characteristics and local water conditions.

  • Saltwater Pools: In saltwater pools, the EC level is typically higher due to the added salt. Generally, the recommended EC range for saltwater pools falls between 3,000 and 5,000 µS/cm. This higher EC level is necessary for the proper operation of salt chlorine generators.

What is Total Dissolved Solids (TDS) for swimming pools?

 Total Dissolved Solids (TDS) are an important parameter to monitor in swimming pools because they represent the cumulative concentration of all dissolved materials in the pool water. TDS includes minerals, salts, organic matter, and other impurities that can accumulate over time due to various factors like evaporation, chemical treatments, and contamination from swimmers and the environment. Here's the importance of TDS in swimming pools: 

  • Water Quality: High TDS levels can affect the clarity and overall quality of pool water. Excess TDS may lead to cloudy or dull water, reducing the aesthetic appeal of the pool and potentially causing discomfort for swimmers.

  • Equipment Efficiency: Elevated TDS levels can put added strain on pool equipment, such as filters and pumps. It can lead to reduced equipment efficiency and lifespan, potentially resulting in higher maintenance and replacement costs.

  • Scaling and Corrosion: Extremely high TDS can contribute to scaling on pool surfaces and equipment, as well as corrosion of metal components. This can lead to costly repairs and maintenance.

  • Chemical Imbalance: High TDS can make it more challenging to maintain proper water balance, which is essential for swimmers' comfort and the effectiveness of pool chemicals.

 The recommended TDS levels for swimming pools can vary based on factors like pool type, local water conditions, and specific equipment. Generally, the following TDS guidelines can be considered:

Freshwater Pools: TDS levels in freshwater pools should typically be maintained below 1,500 to 2,000 parts per million (ppm). Regular water testing and partial water replacement (draining and refilling) may be necessary to manage TDS levels in freshwater pools.

Saltwater Pools: Saltwater pools naturally have higher TDS levels due to the salt used in the system. The acceptable range for TDS in saltwater pools is typically around 3,000 to 5,000 ppm.

How to Reduce TDS in your pool

There are multiple ways to reduce TDS in your pool, but for the home pool owner, the easiest and most cost effective way to do this is to partially drain your pool and refill with fresh water. If you do this, be sure to check all of the levels after refilling and adjust your chemical levels as appropriate.

What is Oxidation-Reduction Potential (ORP) for swimming pools?

 Oxidation-Reduction Potential (ORP) is a crucial parameter in swimming pools and water treatment systems because it measures the water's disinfection capability and the overall effectiveness of the sanitizing agents, such as chlorine. Here's the importance of ORP in swimming pools: 

  • Water Disinfection: ORP is a direct indicator of a pool's ability to effectively disinfect and sanitize the water. It measures the pool's oxidative strength, primarily provided by chlorine or other disinfection agents. Maintaining an appropriate ORP level ensures that the water is free from harmful microorganisms like bacteria and algae, providing a safe and healthy swimming environment.

  • Water Clarity: Proper ORP levels help in preventing the growth of algae and the formation of cloudy or green water. This results in crystal-clear pool water, enhancing the pool's aesthetics and swimmer comfort.

  • Chemical Efficiency: Maintaining the right ORP levels ensures that the pool chemicals, especially chlorine, are operating at their optimal disinfection capacity. This helps in reducing the overall chemical consumption and the associated costs while ensuring that swimmers are not exposed to under-chlorinated or over-chlorinated water. 

The recommended ORP levels for swimming pools can vary depending on factors like pool type, water temperature, bather load, and the specific chlorine system used. However, in a general sense:

Freshwater Pools: The recommended ORP range for freshwater pools is typically between 650 mV (millivolts) and 750 mV. Keep in mind that specific pool management systems and chemical controllers may have slightly different target ranges.

Saltwater Pools: ORP levels in saltwater pools are often maintained in a similar range, typically between 650 mV and 750 mV, though some variations may apply depending on the equipment and control systems in use.

What is Specific Gravity (S.G.) for swimming pools?

 Specific Gravity (S.G.) is a measurement that indicates the density or salinity of the pool water, especially in saltwater pools. Here's the importance of S.G. in swimming pools: 

  • Salinity Control: S.G. is a crucial parameter in saltwater pools, as it directly correlates with the concentration of salt in the water. Maintaining the appropriate S.G. level is essential for the effective operation of salt chlorine generators or saltwater chlorination systems. Incorrect salinity levels can result in inefficient chlorination, which may lead to water quality issues.

  • Swimmer Comfort: The right S.G. level ensures that the pool water feels comfortable to swimmers. Water that is too salty can be unpleasant and may cause skin and eye irritation. On the other hand, water that is too dilute (low S.G.) may not provide the buoyancy that swimmers expect in saltwater pools.

  • Equipment Protection: Proper S.G. levels are necessary to protect the equipment in saltwater pools. High or low salinity levels can cause premature wear and tear on pool equipment and may lead to corrosion or scaling issues. 

The recommended S.G. level for swimming pools, particularly saltwater pools, typically falls within the range of 1.025 to 1.035. However, the specific target S.G. may vary depending on the type of pool equipment, the manufacturer's recommendations, and local water conditions. It's important to follow the guidelines provided by the manufacturer of your salt chlorine generator or saltwater chlorination system.
