If you have a swimming pool and live in the South and Southwest United States you’re going to deal with high calcium levels in your swimming pool. Over the years we’ve learned that high calcium levels are also extremely common in many other places in the United States and world. As water evaporates in a swimming pool, calcium and other hardness minerals stay behind in solution and start to stain the tile, liner of the swimming pool and equipment. If you have decorative tile, fountains or other water features this can make looking at them extremely frustrating because the staining gets worse and worse and it can make your backyard paradise look like an eyesore. In the swimming pool industry, it’s recommended to have your calcium levels between 200-400 parts per million (ppm). In some parts of the United States, the water coming out of the tap is 400ppm and above. When calcium levels get high, we recommend recycling your swimming pool using the “Puripool Process” in our mobile filtration system. It conserves 85% of the water in the swimming pool, gives you much better water than a drain and refill and prevents damage to your swimming pool when you drain it.

Recently, we were called out to a residential 18,000 gallon swimming pool because they complained of high calcium levels. When we arrived at the house the initial chemistry was as follows….

Total Dissolved Solids – 4850ppm

Calcium Hardness – 820ppm

Cyanuric Acid – 180ppm

After filtering the swimming pool for 11 hours and conserving roughly 14,500 gallons we left our customer with the following chemistry….

Total Dissolved Solids – 820ppm

Calcium Hardness – 150ppm

Cyanuric Acid – 60ppm

The ending chemistry is perfect when dealing with a swimming pool. The residents lost no time with their swimming pool, we also lowered total dissolved solids and cyanuric acid and conserved water at the same time which is key during our current drought conditions. If you should have any questions in regards to our Puripool Process please give us a call 1-800-535-0778!
