TDS and Calcium Hardness Challenges With Your Swimming Pool

If you own a swimming pool in Las Vegas are you are going to need to understand the term Total Dissolved Solids (TDS). TDS is best described by, “the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm).” In the pool industry TDS is directly related to the purity of water and usually a number that is referred to when it’s time to replace the existing water in your swimming pool. Between TDS and Calcium Hardness (CH), it’s the two most common factors in the pool industry as to why a water change will be recommended.

Dissolved solids come from organic sources such as leaves and silt, it can also come from fertilizers and pesticides too. Dissolved solids also come from inorganic materials such as rocks and air that may contain calcium bicarbonate. But, the most common place that these dissolved solids come from is our water. The water picks up many of these metals because of where it is sourced (The Colorado River) which is loaded with limestone and over time causes numerous problems to the interior finish of the swimming pool, the tile, and your pool water filtration equipment.

As water evaporates, the minerals remain in solution and slowly destroys the surface of the swimming pool but can also make it harder to handle the water chemistry as well. The general rule of thumb is to change out the water every 2 years. If you take a water sample into a pool store they will usually recommend changing out your water when TDS levels climb above 3,000ppm.

Even though we prefer to change out your water when Calcium Hardness levels rise, we realize that TDS is a widely used number in the swimming pool industry. When it comes time to change out the water in your swimming pool we recommend using our Pool Water Recycling method, which is a Reverse Osmosis (RO) Mobile Filtration system that comes to your home or commercial property and recycles the existing water in the swimming pool.

Our mobile filtration trailers are equipped with high-pressure RO membranes that can lower calcium, TDS and other hardness minerals while conserving 85% of the water in the swimming pool. With drought conditions in the news and high temperatures, water conservation is in the news. Some of the benefits of our mobile filtration system are:

  • Water Conservation
  • Lowers Calcium Hardness
  • Lowers TDS
  • Lowers Cyanuric Acid (CYA)
  • Lowers Salt Levels
  • Doesn’t Expose The Surface of The Swimming Pool
  • Lowers Phosphates
  • Removes Waterborne Diseases (Crypto)
