The effects of calcium on your swimming pool if you live in the Phoenix area are pretty substantial. When you own a swimming pool with a dark interior finish, tile or spillway those effects increase a lot more. Our tap water is extremely hard in the Greater Phoenix area. Typically, it is coming out of the tap at 400 parts per million (ppm) and higher. If you’re familiar with normal levels for a pool this is on the higher end because the recommended amounts of calcium are between 200-400 ppm. With that said, as your pool water evaporates, the hardness minerals remain in solution and gradually build up in concentration. As these levels rise to 600ppm and higher, scaling on your tile, interior finish, filtration equipment, spillways and decorative water features will occur. That’s why you will need to educate yourself on calcium and why it’s vital in keeping the levels low.

At Monarch Pool Sevice it is not uncommon for us to walk into a backyard and see the above. As you can tell they have a darker interior finish and raised spa. With higher levels of calcium hardness, it won’t take long for scaling to occur and to frankly make it look like an eyesore. Unfortunately, when residential swimming pool owners design a swimming pool this isn’t something they think about. They have a vision in their head and when it is designed it looks incredible but as time goes on, more and more scaling will occur and it can become quite expensive if you hire a tile cleaner to come out. That’s why our mobile filtration system is your answer to help prevent this in the future.

We use Reverse Osmosis (RO) filtration to lower calcium hardness, total dissolved solids (TDS), cyanuric acid (CYA), phosphates, salts, and waterborne diseases without draining the swimming pool. With this type of filtration, we can lower your calcium levels far below tap water. The above pool was just recently filtered and we want to share how things went!

Initial Chemistry

Calcium Hardness – 750ppm

Total Dissolved Solids – 3720ppm

CYA – 200

As you now should understand with calcium hardness levels as high as 750ppm scaling will definitely occur but after filtering this pool for 7 hours we were able to lower everything to the following:

Ending Chemistry

Calcium Hardness – 180ppm

Total Dissolved Solids – 469ppm

CYA – 0

Again, by using RO filtration we are able to take calcium to levels approximately¬†220ppm lower than tap water. That’s why with swimming pool like this it is vital to use our service every 1-2 years to prevent major calcium build up again. It will be like swimming in drinking water which is better for you and your family. If you’re interested in learning more, contact us today!
