As a resident in Las Vegas with a swimming pool, you’re going to need to familiarize yourself with how to remove calcium from your swimming pool. Even though your swimming pool needs some calcium in the water to maintain the integrity of the interior finish, our fill/tap water has too much! The ideal range for Calcium Hardness (CH) in the pool industry is between 200-400 parts per million (ppm) and you will want to make sure that it’s not too soft (below 100ppm) or too hard (over 600ppm) because this is where problems occur. When dealing with calcium levels below 100ppm the water will be too soft and it will cause long-term serious damage especially to the interior finish (plaster), vinyl liners, grout in between tiles, metal rails, and even concrete decking around the pool. This occurs because it is very aggressive and it actually seeks to dissolve and bring into solution minerals, metals, and other substances. Although homeowners love to have soft water in their house, it isn’t ideal for your swimming pool!

Whereas, when CH levels in your swimming pool rise above 600ppm which is extremely common in the Las Vegas area there is a multitude of other issues that occur! Most swimming pool owners always ask, “What is this white stuff all over my swimming pool?” It’s calcium and when levels get high in your swimming pool it will scale the water tile line, the interior finish, filtration equipment, spillways, and decorative water features. It can make handling the chemistry in your swimming pool more challenging and most importantly if you don’t lower it soon, it can be extremely costly to remove!

So, what happens when levels climb above 600ppm and how do you remove it?

When this happens, you have two choices…

  1. Drain and refill
  2. Reverse Osmosis (RO) Mobile Filtration

In Las Vegas, if you choose to drain and refill your swimming pool there’s a huge risk of damaging your interior finish, the process takes 2-3 days and you will be filling your pool back up with moderately hard water. The water coming out of the tap ranges from 300-400ppm which as you recall is on the higher end of what is recommended for your swimming pool!

On the other hand, if you choose RO filtration to remove calcium from your swimming pool we can complete most residential swimming pool jobs in less than a day, you can swim in the pool during filtration and we replace your current water with calcium levels in the area of 150ppm which is far below tap water. The water quality will be much better, you will enjoy swimming in your pool more and it will prolong the lifespan of your investment. If you’re curious to know more, please contact us today!
