Lowering Calcium Hardness and TDS In Your Pool In Phoenix

If you own a residential or commercial swimming pool and live in the Greater Phoenix area where high levels of calcium, magnesium, or other hardness minerals are in your tap water then we think this blog post is going to be extremely informative for you. In Phoenix, Arizona, we deal with high levels of Calcium Hardness coming out of our tap water. People will refer to their water as being “hard” because these minerals build up in the pool water and begin to cause problems. These levels will vary depending on where you live and depending on who you talk to but it doesn’t take long for these numbers to increase especially in the summertime. Every single day that your water evaporates and new tap water is added these numbers will increase in parts per million (ppm). This is common in our area and that is why we offer services for both residential and commercial swimming pool owners to combat it.

As water evaporates in your swimming pool (up to an inch a day during the summer) the hard minerals remain in the solution and gradually increase in concentration. As these levels increase, the calcium and other hardness minerals will scale on the water tile line, the interior finish, the water features, and the filtration equipment of the swimming pool. If you own a salt chlorinator, it will scale the electrode plates as well.  As for the pool, it is not only hard to look at but it will cause major damage to your swimming pool if you don’t take care of it and it can be very expensive to remove. Typically, at this point most pool professionals will recommend a drain and refill, and here are some of the pros and cons:

Drain and Refill Compared To Recycling Your Pool Water


  • Relatively inexpensive especially if you don’t hire a professional
  • The water will be better than what is currently in your pool but in some areas even when you drain it the levels will still be what is considered higher than are recommended levels.


  • The water is still hard coming out of the tap
  • The interior finish is exposed which can be dangerous
  • 2-3 day process

Whereas, if you consider recycling your swimming pool water with Pool Water Recycling, we guarantee a much better end product. We can take calcium levels below 200 ppm. At Pool Water Recycling, we offer a mobile filtration system that comes to your residential or commercial property and recycles the water onsite. The mobile filtration trailer is equipped with Reverse Osmosis (RO) filtration that returns exceptional quality water to the swimming pool. The process is completely self-contained which means we run on our own power and we guarantee you better water than tap. The following are some of the benefits of recycling your pool water:

  • Water conservation – we conserve up to 85% of the existing water
  • No downtime – you can swim in the pool while the process is being performed
  • Drinking quality water in your swimming pool
  • The interior finish is never exposed
  • Soft water
  • Removal of waterborne diseases
