Recycling Pool Water

High Calcium Hardness and CYA In Dallas Pools

In the Dallas area, we deal with excessively high levels of Calcium Hardness in our swimming pools. This happens because our fill/tap water is hard. The water coming out of our tap is loaded with calcium, magnesium and other hardness minerals that will scale your water tile line, interior finish, filtration equipment, decorative water features, and salt systems. This happens because as your water evaporates, the hardness minerals will remain in solution and gradually build up in concentration. When this occurs the scaling will occur which leads to problems for both residential and commercial swimming pool owners. Typically, the following are some of the problems:

  • Scaling on your water tile line
  • Staining of the interior finish
  • Increased chemical usage
  • Your water will feel old
  • A decreased lifespan of all filtration equipment and interior finish

Swimming pools take a beating. Hard water will cause a lot of damage to them if you don’t monitor your Calcium Hardness, Total Dissolved Solids (TDS), and Cyanuric Acid (CYA) levels regularly. As a general rule of thumb, most pool professionals including us will recommend a water change every two years! Why? We recommend every two years to prevent a lot of the issues described above from happening and to keep your pool looking great!

At Weber Pools, we offer Reverse Osmosis (RO) mobile filtration as an alternative to pool draining. This service is mobile and comes to your home or commercial property and recycles the water onsite. Since we use RO filtration we are able to lower these major problems while conserving 85% of the existing water in the swimming pool which means no exposed interior finish and no downtime!

Just this past week we recycled a 17,000-gallon swimming pool that was struggling with high hardness and Cyanuric Acid (CYA). The following is the initial water chemistry:

Calcium Hardness – 700ppm

Total Dissolved Solids – 46t42ppm

CYA – 300+ (high levels of CYA will bind up chlorine and prevent it from working correctly)

After filtering this swimming pool for 14 hours we were able to lower the above levels to the following:

Calcium Hardness – 160ppm

Total Dissolved Solids – 632ppm

Cyanuric Acid – 40ppm

High levels of Calcium Hardness in your swimming pool can cause scaling and high levels of CYA can prevent chlorine from working efficiently. When that happens your pool can turn cloudy and algae will grow. Keeping a balanced water chemistry is extremely important and using our RO filtration to lower your hardness minerals can make it so much easier.
