High Salinity Issues with Swimming Pools
If you have been following along with Pure Water Industries blog for quite a while it shouldn’t surprise you that we discuss what high levels of Calcium Hardness (CH) and Total Dissolved Solids (TDS) will do to your swimming pool. More specifically what it will do to your tile, decorative water features, and your filtration equipment. At the end of the day, your swimming pool is a large investment and in many areas of the country, the hardness in the tap water will cause problems over time if you don’t change out the water. Another issue that we have discussed from time to time is what high levels of salt will do to your swimming pool as well. Just this past week we pulled up to a 20,000-gallon swimming pool with extremely high hardness, TDS, and salinity levels. The following was the initial water chemistry:
Calcium Hardness – 2000 ppm
Total Dissolved Solids – 16,840 ppm
Salinity – 10,450 ppm
In the swimming pool industry, the recommended levels of Calcium Hardness are between 200 – 400 ppm and most pool professionals will recommend changing out the water in your swimming pool when TDS levels are higher than 3000 ppm in a non-salt pool. That’s why when we were on site of this 20,000-gallon swimming we noticed all the calcium scaling on the tile and the corrosion that the high levels of salt caused on the outside of their variable speed motor. Could you imagine what this is doing to the rest of their swimming pool?
Why Pool Water Gets Hard
As a swimming pool owner, it is extremely important to familiarize yourself with Calcium Hardness and TDS. In many areas of the country, as your pool water evaporates the hardness minerals remain in solution and gradually build up in concentration. When this happens the calcium will begin to scale your tile, interior finish, plumbing, water features, filtration equipment and so much more! When this happens, it is extremely expensive to remove and it will take life off of your pool and filtration equipment.
At Pure Water Industries, we highly recommend changing out the water in your swimming pool every two years. This will help prevent the issues we mentioned above and prolong the lifespan of your investment. It will also prevent costly repairs to your pool filtration equipment.
In summary, we recommend recycling your swimming pool water with The Puripool Process to give you the best water quality to swim in. By using Reverse Osmosis filtration you will achieve much better results than a typical drain and refill.
