You can raise the total hardness in a pool by adding calcium chloride or calcium chloride dihydrate. Follow the manufacturer's instructions for the correct dosage based on your pool's size and current hardness levels. It's important to test the water regularly to ensure the hardness remains within the recommended range.
No, baking soda does not increase calcium hardness in a pool. It is used to raise alkalinity and help stabilize pH levels in pool water. To increase calcium hardness, you would need to use calcium chloride.
Baking soda will not soften (remove calcium hardness) from pool water. It will raise total alkalinity.

Adding calcium chloride flakes to pool water can help raise the calcium hardness level, which is important for preventing corrosion of pool equipment and reducing the risk of plaster etching. It can also help to stabilize the water chemistry and prevent scaling in the pool.
If the calcium is a result of pool chemicals, draining some or all of the pool water will lower the calcium hardness level. If the cause is the fill water, commercial hardness reducers or chelating agents will bond with the calcium to keep it trapped in solution.

Buildup of minerals like calcium.
Permanent hardness of water is caused by the presence of dissolved calcium sulfate and magnesium sulfate, which cannot be removed through boiling. These minerals form insoluble compounds that remain in the water even after treatment, leading to permanent hardness.

The hardness of bone is primarily due to its mineral content, mainly consisting of calcium and phosphate that form a hard mineral called hydroxyapatite. This mineral provides bone with strength and rigidity, making it a durable and protective structure in the body.
The recommended frequency for checking calcium hardness in swimming pools is once a month. Other water tests will depend on how often the pool is used.
