Understanding Water Hardness
Causes of Hard Water
Hard water is characterized by high concentrations of calcium and magnesium ions. These minerals occur naturally in water sources, dissolving from rocks and soil as water flows through them. Consequently, the local geology has a significant impact on the mineral content of water. Concentrations of calcium and magnesium in hard water can lead to various issues, such as the formation of scale deposits on pool surfaces and equipment, reduced effectiveness of cleaning agents, and potential imbalances in pool chemistry.
Measuring Water Hardness
There are generally two standard units used to measure water hardness: parts per million (ppm) and grains per gallon (GPG). Both units indicate the concentration of calcium and magnesium ions in the water, with 1 GPG being equivalent to approximately 17.1 ppm. A water hardness test kit can provide a quantitative measurement of water hardness, usually in the form of calcium carbonate (mg-CaCO3/L).
The following table provides a general classification of water hardness levels:
|Hardness in mg-CaCO3/L
|Hardness in mmol/L
|0 – 70
|0 – 0.7
|71 – 140
|0.71 – 1.4
|141 – 210
|1.41 – 2.1
When managing swimming pool water, it’s crucial to maintain water hardness within recommended ranges, usually 200 to 400 ppm, to prevent problems related to hard water. Methods to address hard water in pools include adding softening chemicals, partially draining and refilling the pool with softer water, and using pool flocculants. Each of these methods can help reduce water hardness and maintain a balanced pool environment.
Effects of Hard Water on Pool and Equipment
Calcium Buildup and Scaling
Hard water in pools is mainly caused by high levels of calcium hardness. Excess calcium results in the formation of scale, a hard, crusty deposit that consists primarily of calcium carbonate. This scale can buildup on pool walls, appliances, and other equipment, leading to a range of issues, such as:
- Unsightly appearance: Scale deposits can give pool walls a rough, unsightly appearance.
- Reduced efficiency: Scale buildup on appliances and equipment can impair their performance.
- Increased maintenance: Regular cleaning and descaling is required to prevent future scaling.
Damage to Pool Walls and Equipment
High levels of calcium hardness in pool water can have damaging effects on both concrete/plaster pool walls and metal equipment. Some of the potential damages include:
Pool Walls and Plaster
- Erosion: Soft water can strip chemicals from pool walls, causing them to erode and weaken over time.
- Concrete damage: Excessively soft water can even dissolve hard surfaces like concrete and plaster, leading to structural damage.
- Corrosion: Soft water is corrosive to metal equipment, like pumps, filters, and heating systems, reducing their lifespan.
- Accumulation of Water Softener Salts: The use of water softeners can cause a buildup of salts in the pool equipment, potentially causing damage.
In order to prevent these issues, it is essential to maintain a proper balance of water hardness in your swimming pool. Proper monitoring and adjustments can help prolong the life of your pool walls and equipment while ensuring a comfortable swimming experience for users.
Pool Water Softening Solutions

Using chemical softeners is an effective method. However, it is essential to follow the dosage instructions as per your pool size. Regular maintenance checks of your pool water hardness level will help keep it soft and comfortable.
Filtration systems are another excellent solution to soften pool water. These systems work by filtering out minerals and other impurities that contribute to hard water. There are various types of filtration systems available, such as:
- Saltwater pool systems: These convert salt into chlorine, creating soft water that is gentle on the skin, the pool components, and reducing the buildup of minerals.
- Reverse osmosis (RO) systems: RO filtration removes mineral ions by forcing water through a semipermeable membrane, reducing the hardness level in the pool water.
Each filtration system has its benefits, and the choice of which to use will depend on the specific needs of your pool. In addition to softening water, filtration systems often improve the overall water quality and reduce the need for excessive chemicals.
By implementing chemical water softeners or filtration systems, you can reduce mineral content in your pool, protecting pool components, and providing a more enjoyable swimming experience. Regular pool maintenance and water testing will ensure the best results for your soft water pool.
Maintaining Pool Water Balance
Maintaining pool water balance is crucial for swimming pools and hot tubs to prevent cloudy water, odor, and stains. It involves managing various components, including pH, alkalinity, and calcium hardness. Properly balanced water also saves money on pool water treatment and plays a crucial role in extending the life of the pool equipment.
Adjusting pH and Alkalinity
The pH level measures the acidity of pool water, with the ranges from 0 (acidic) to 14 (basic). The ideal pH level for swimming pools is 7.4-7.6. Alkalinity refers to the ability of pool water to keep its pH level stable and prevent fluctuations. The recommended alkalinity level for pools is 80-120 ppm.
- Hot tubs and swimming pools: Regularly test both pH and alkalinity levels to ensure stability. Chlorine works best when the pH level is within the ideal range.
- Concrete and plaster pools: High pH can lead to scale formation and negatively affect concrete and plaster pool surfaces.
- Lowering pH: If the pH level is too high, use muriatic acid to lower it.
- Raising pH: If the pH level is too low, add a pH increaser, such as sodium carbonate, to raise it.
- Alkalinity adjustment: Use sodium bicarbonate to raise alkalinity if it’s too low. Use muriatic acid to lower alkalinity if it’s too high.
Managing Calcium Hardness
Calcium hardness is the measure of dissolved calcium in your pool water. It’s essential to maintain the proper calcium hardness level to avoid potential problems like cloudy water, scaling, or corrosion.
- Ideal levels: The recommended calcium hardness level for pools lies between 200 and 400 ppm.
