If it’s time to change out the water in your swimming pool you will have a couple of different options. First many residential and commercial swimming pool owners will probably ask why would I have to change out the water in my swimming pool? Typically, most swimming pool owners will need to change out the water in their swimming pool for the following reasons:

  • High Calcium Hardness (CH)
  • High Total Dissolved Solids (TDS)
  • High Cyanuric Acid (CYA)
  • High Phosphates
  • High Salts
  • Presence of waterborne diseases like Cryptosporidium (Crypto)

Now that it is fall in the Las Vegas area, it is much safer to drain a swimming pool so this topic comes up a lot now especially if any of the above issues are high. Even though you have a choice, at Clark County Pool & Lawn we believe there is only one decision you can make.

Typically, most pool professionals will recommend a water change when the above occurs because it will cause calcium scaling on the water tile line, the interior finish, filtration equipment, spillways, and decorative water features. When scaling occurs it can make your backyard paradise tough to look at and it can be extremely costly to have it removed. Calcium in the Las Vegas area is present in the tap/fill water. When pool water evaporates, calcium will remain in solution and gradually build up in concentration. This will cause your TDS to rise too. Over time, as calcium scales on the interior finish and filtration equipment, it will take life off of your swimming pool and equipment.

To combat this problem and to alleviate some of the other issues that are listed above, you can either drain your swimming pool or recycle the water using our Reverse Osmosis (RO) mobile filtration equipment. We call this pool water recycling. If you choose to drain your swimming pool it can take up to 2-3 days to perform this process, there’s a chance you could damage the interior finish and you will be filling it up with our extremely hard water again. Whereas, if you choose to recycle your swimming pool water it will leave you with drinking quality water conditions, it can be performed in less than a day and you can swim in the pool during filtration. This past week we were called out to a 30,000-gallon residential swimming pool with the following chemistry:

Initial Chemistry

Calcium Hardness – 1110ppm (high)

Total Dissolved Solids – 5650ppm (high)

CYA – 50ppm (within range)

After filtering this swimming pool for 22 hours we were able to leave them with the following ending chemistry and conserve 85% of the existing water in the swimming pool.

Ending Chemistry

Calcium Hardness – 110ppm (better than tap water)

Total Dissolved Solids – 760ppm

CYA – 0ppm

When comparing RO to a typical drain and refill it is much better because we give you water that is better than tap, you will notice that the water is softer and there’s no risk of cracking the foundation of the pool because the water level never changes. If you have the option to perform RO on your pool water it is the smartest decision. If you should have any questions about how this service is performed, please contact us today!
