Understanding Calcium Hardness
Calcium hardness refers to the amount of dissolved calcium in your pool water. It’s a critical factor in maintaining water balance. The ideal range for calcium hardness in pools is typically between 200-400 ppm (parts per million). Levels below this threshold can lead to corrosive water, which can harm your pool’s surfaces and equipment.
Why is Calcium Hardness Important?
Preventing Corrosion
Low calcium hardness can cause your pool water to become corrosive. This means it can leach calcium from pool surfaces, leading to etching and damage over time. By maintaining proper calcium levels, you can protect your pool’s structure and extend its lifespan.
Protecting Equipment
Corrosive water can also affect pool equipment such as pumps, heaters, and filters. By ensuring your calcium hardness is within the recommended range, you can avoid costly repairs and replacements.
Enhancing Water Clarity
Proper calcium levels contribute to clearer water. When calcium hardness is balanced, it helps to stabilize pH levels, reducing cloudiness and improving overall water quality.
How to Measure Calcium Hardness
Measuring calcium hardness in your pool is a straightforward process. You can use test kits available at stores like www.homedepot.com or online at domain sites like shastapoolsupply.com. Simply follow the instructions provided with the kit, and you’ll obtain an accurate reading of your pool’s calcium levels.
How to Increase Calcium Hardness
Step-by-Step Guide
- Test Your Water: Use a reliable test kit to determine your current calcium hardness level.
- Choose the Right Product: Select a calcium hardness increaser that suits your pool size. Options include products from hthpools.com or lesliespool.com.
- Calculate the Required Amount: Refer to the product label for instructions on how much to add based on your pool’s volume.
- Dissolve the Product: For easier application, dissolve the calcium increaser in a bucket of water before adding it to the pool.
- Distribute Evenly: Pour the dissolved product around the perimeter of the pool while the pump is running to ensure even distribution.
- Retest Water: After 24 hours, retest your water to ensure calcium levels have reached the desired range.
Common Mistakes to Avoid
Overdosing
Adding too much calcium hardness increaser can lead to excessively high calcium levels, which can cause scaling and cloudy water. Always follow the manufacturer’s guidelines.
Ignoring pH Levels
When adjusting calcium hardness, it’s essential to monitor pH levels as they can be affected. Aim for a pH range of 7.2 to 7.8 for optimal water balance.

FAQ
What is calcium hardness?
Calcium hardness refers to the concentration of dissolved calcium in your pool water, which is crucial for preventing corrosion and maintaining water clarity.
Why do I need to increase calcium hardness?
Increasing calcium hardness is necessary if your pool water is below the recommended range of 200-400 ppm, which can lead to corrosive conditions.
How often should I test my pool’s calcium hardness?
It’s recommended to test your pool’s calcium hardness at least once a month, or more frequently if you notice changes in water quality.
What happens if calcium hardness is too high?
Excessively high calcium hardness can lead to scaling, cloudy water, and potential damage to your pool equipment.
How do I know which calcium hardness increaser to use?
Choose a product based on your pool size and the current calcium levels. Refer to product labels for guidance on dosage.
Can I use calcium hardness increaser in a hot tub?
Yes, calcium hardness increasers can be used in hot tubs as well, but ensure that you follow specific dosage instructions for smaller volumes of water.
How long does it take for calcium hardness increaser to work?
Typically, you should see results within 24 hours after adding the increaser and running the pool pump.
Is there a difference between calcium chloride and calcium carbonate?
Yes, calcium chloride is more soluble and acts faster, while calcium carbonate has a slower effect and can slightly raise pH levels.
What are some signs of low calcium hardness in my pool?
Signs include corrosive water, etching on surfaces, and visible damage to pool equipment.
Where can I buy calcium hardness increasers?
You can find calcium hardness increasers at home improvement stores like www.homedepot.com, pool supply websites like hthpools.com, or local pool supply shops.
