Many people will ask, “Is Calcium Dangerous For Your Swimming Pool?”

Calcium is great for many things. As humans having enough calcium is great for your teeth and bones but excessive calcium levels can cause issues with not only humans but with swimming pools too! In the end, calcium is dangerous for your swimming pool if you have too much! When it comes to Calcium Hardness (CH) in tap water, Las Vegas is extremely high compared to many other areas in the country. In our area, the calcium coming out of the tap water is higher than what is recommended for a swimming pool but it’s important to note that swimming pools need a certain amount of calcium to keep the interior finish intact but there are issues when it gets too high. For swimming pools, the standard and recommended amount of Calcium Hardness is between 200 – 400 parts per million (ppm) but in certain areas of the country, like Las Vegas, the Calcium Hardness coming out of the tap is 400ppm and higher! The challenges for residential swimming pool owners is when calcium levels get too high in their swimming pool. When these levels continue to climb scaling occurs on the water tile line, the interior finish, filtration equipment, decorative water features, salt chlorinators, and spillways. It can also be challenging to manage the water chemistry too!

So what happens when calcium levels get too high? The simple answer is it must be removed/lowered from the swimming pool water. At this point you can choose to drain and refill your swimming pool which takes 2-3 days, can damage your interior finish and you will be filling it back up with your cities hard water or you can recycle it using Clark County Pool & Lawn’s Reverse Osmosis (RO) mobile filtration trailer. We offer mobile filtration to lower Calcium Hardness, Total Dissolved Solids (TDS), Cyanuric Acid (CYA), phosphates, salts, and waterborne diseases without draining the swimming pool. This service puts drinking quality water back in your swimming pool and you can swim in the pool while it is being filtered. Not to mention, we conserve up to 85% of the existing water in the swimming pool which is great for water conservation/drought-stricken areas like ours.

So if you commonly take your swimming pool water into a pool store to have it tested be prepared for them to tell you to drain and refill your swimming pool if the calcium, TDS, or CYA is too high. Finally, since we have determined that high levels of calcium are dangerous for your swimming pool, we highly recommend changing out the water in your pool every two years to prevent scaling and heavy expenses to remove it.
