Reverse Osmosis To Lower Calcium Hardness, TDS, and CYA

When it comes to owning a residential and commercial swimming pool other than keeping it clean and monitoring water chemistry weekly, familiarizing yourself with Calcium Hardness, Total Dissolved Solids (TDS), and Cyanuric Acid (CYA) should be a priority especially if you live in Southern California. Our tap water is loaded with calcium, magnesium, and other hardness minerals and it will cause your Calcium Hardness levels to rise. As far as sanitizer goes, if you use liquid chlorine in your swimming pool that will cause TDS to rise and if you happen to use chlorine tabs (which are extremely common) that will cause your CYA levels in your swimming pool to increase. Any and all of these issues can make owning a swimming pool more challenging and that’s why at Pure Water Industries, we want to educate you on what you should do when any of them get higher than what is recommended. That is why we wrote this blog post and we want you to familiarize yourself with the following industry standards:

  • Calcium Hardness: 200 – 400 ppm (in some areas of the country it is higher)
  • Total Dissolved Solids: less than 3000 ppm
  • Cyanuric Acid: 30 – 50 ppm (if you own a salt chlorinator refer to the manual as these numbers can be higher)

So, what happens when any of the above levels get higher than what is recommended? Most pool professionals will recommend a drain and refill which will lower calcium and TDS levels but it wastes water and we have a much better option

The Puripool Process

Pure Water Industries offers The Puripool Process which is the best alternative to a drain and refill. Since this service is mobile, it comes to your residential or commercial swimming pool and recycles the water onsite. It uses Reverse Osmosis (RO) filtration to lower Calcium Hardness, TDS, CYA, phosphates, nitrates, salts, and waterborne diseases without draining the swimming pool. This means no downtime and much-needed water conservation! It also means that you, your family, and all bathers will be swimming in the best water quality.

The water will not only look better but it will feel better too! To learn more about this service, why it’s the smarter decision, and to book an appointment today, contact us!
