If you live in the Southwest United States dealing with extremely high calcium levels coming from your tap water is the norm. Depending on where you are at (Arizona, California, or Nevada) our water is extremely hard. The tap water is loaded with calcium, magnesium and other hardness minerals. When this water is introduced into your swimming pool it is usually harder than what is recommended for your pool (200 – 400 parts per million). In the San Diego area, calcium hardness coming out of the tap ranges from 300 – 400 ppm. This is a challenge for most swimming pool owners because as water evaporates, the hardness minerals remain in solution and gradually rise in concentration. When calcium hardness gets into the area of 600 parts per million (ppm) and higher scaling will begin to occur on the water tile line, the interior finish of the swimming pool, pool filtration equipment, spillways and decorative water features. Depending on the color of tile, the extent of your water features and how long you leave your current water in the pool is directly proportional to how much calcium scaling you will have and how challenging it will be to remove it! Please note, if you need to hire a professional to come in and remove the calcium from the tile, it’s an expensive operation.
Typically, if you wait many years with hard water in your swimming pool you will need to call a professional to come and remove it from the surface of your swimming pool. Depending on how thick it is will determine the price and the more areas affected will cause the price to rise. One way to do this would be to get in the habit of changing out the water in your swimming pool every two years and at Pure Water Industries, we recommend recycling your water instead of a typical drain and refill because we can give you better water than tap and we can also conserve up to 85% of the existing water in the swimming pool. Earlier this week we processed a 25,000-gallon swimming with extremely high hardness. The swimming pool owner decided on hiring us because of our current drought condition and they couldn’t imagine wasting that much water. Upon entry to their swimming pool, we tested their water at:
Calcium hardness – 1030 ppm (extremely high)
Total Dissolved Solids – 3170 ppm
Cyanuric acid – 200 ppm
After filtering this swimming pool for 13 hours we were able to conserve 21,000-gallons of water and we provided them with this finished product:
Calcium hardness – 180 ppm
Total Dissolved Solids – 757 ppm
Cyanuric acid – 80 ppm
This is a service we provide for residential and commercial swimming pool owners. You can swim in the pool while filtration is occurring which means no downtime. Since we put drinking quality water back in your pool it’s the best quality of water you can have. Trust us when we say you will love swimming in our pools and if you’re dealing with high hardness, contact us today to book an appointment.
