Knowing how to reduce calcium hardness in pools is important to keeping pool water clear and balanced. When the calcium level is too high, excess minerals in the water make it challenging to maintain proper pH and alkalinity levels. Achieving the optimal levels for a clean and clear swimming pool requires adding pool chemicals more frequently, and adding more of them.
To achieve the ideal water hardness, you may need to lower the calcium level. There are several ways you can do this.
The Ideal Swimming Pool Water Hardness
If the water in your pool appears cloudy and you notice sediment buildup on the bottom, and adding clarifiers and shock doesn’t solve the issue, you likely have hard water. Test the water to determine the calcium level. It should read between 155 and 400 parts per million (ppm); aim for about 275 ppm for the most balanced water.
To achieve the ideal calcium level, pool professionals first balance the water’s pH, then the alkalinity, and finally the calcium.
The Best Ways to Reduce Your Swimming Pool Water Hardness Level
If testing reveals the pool water’s hardness is over 400 ppm, you need to know how to reduce calcium hardness in a pool before adding more pool chemicals. You have three options.
Add Fresh Water
The easiest way to reduce the calcium level in the pool is to drain about a quarter of the water and add fresh water. If you aren’t sure how much water to remove, check with a pool professional. They can estimate how much water to drain to restore calcium balance without wasting water.
Once you drain water from the pool, using either a siphon or the filter’s backwash setting, replace it with fresh water. Wait at least six hours for fresh water to mix with the existing water, then test the calcium again.
Add a Flocculant
Using a flocculant before draining and replacing the water can help reduce calcium hardness in a swimming pool with a water hardness significantly higher than 400 ppm.
Flocculant is an additive that removes free-floating calcium (undissolved calcium) from the pool water. After adding the flocculant to the water and vacuuming the sides and bottom of the pool to remove the remaining calcium carbonate particles, backwash the filter. Drain and replace the water as described above.
Adding muriatic acid or dry acid to the pool water does not reduce the calcium hardness. However, it can help balance the water and control the hardness to make pool chemicals more effective. Because improper use can cause corrosion, talk to a pool professional about how to balance the water first
