Maintenance Monday: Why You Need to Maintain Calcium Levels in Your Pool

Why Maintain Calcium Levels in Your Pool?

It’s Maintenance Monday again here at Poolinfloor.com and today we are going to discuss calcium hardness and why it's important to keep an optimal calcium level in your pool. Lets start off with the most important question: What is Calcium Hardness? Calcium Hardness is the measurement of how "hard" or "soft" the water is. Ideal calcium level is somewhere between 200-400 ppm. Calcium levels, although not as important as Chlorine or pH, should still be checked every 2 weeks or so depending on the calcium level of the water in your area. If the water is "too hard" it will lead to irreversible cloudy water, major buildup on the pool tile and even inside the plumbing lines. If the water is "too soft" it becomes corrosive and could possibly dissolve any concrete around the pool and severely corrode metal as well. 


What can you do to balance your Calcium Hardness level?

It is important to clean and backwash your pool as well as the main filter to make sure there are no contaminants that may cause issues in the future. Once the pool is clean, the water itself must be chemically balanced while paying extra attention to the pH level and alkalinity. Once you've achieved the proper balance it becomes fairly easy to raise or lower the calcium level in your pool. 


To raise the calcium level, we recommend using an industry-grade Calcium Hardness Increaser. Make sure you follow the instructions exactly as they are laid out by the manufacturer. 


To lower the calcium level, there are a few different routes for you to take. If possible, you can drain a large portion of your water and replace it with softer water. 

If draining isn't an option, we recommend a flocculant to attract excess calcium in the water, causing it to clump and fall to the bottom of the pool. Once the flocculant has done it's job simply vacuum out the clumps and backwash and clean the filter one more time to remove the calcium. Be sure to test the level afterwards to make sure the first treatment was a success. 


In conclusion, calcium hardness is one of the most important aspects of your pool to keep an eye on. Failure to do so will cause major damage resulting in a large repair. Please take the tips found in this guide and use them to your advantage.
