Lowering Calcium Hardness Levels in Swimming Pools

If you live in the Dallas Ft. Worth area and own a residential or commercial swimming pool, it’s a guarantee that you will have issues with high Calcium Hardness and Total Dissolved Solids (TDS) levels in your swimming pool water. Many people ask us, why does this happen? Honestly, It’s quite simple….. Calcium Hardness is extremely high in our tap/fill water and as water evaporates in your swimming pool, the hardness minerals stay behind and gradually increase in concentration. When dealing with proper water chemistry in a swimming pool, your optimal calcium hardness is between 200 – 400 parts per million (ppm). In the Dallas Ft. Worth area, Calcium Hardness levels coming out of the tap can be 300 – 500 ppm and higher!  With that said, the typical answer on how to deal with high hardness levels in a pool in Dallas would be to drain a swimming pool and fill it up with our moderately hard water again, which not only wastes precious water but it doesn’t always solve the problem. Water quality is huge when dealing with larger bodies of water, especially in warm climates where it is easier for algae to grow in warm water. Instead of draining, Weber Pools gives you the ability to recycle your swimming pool water using our mobile Reverse Osmosis (RO) filtration system. Our “Puripool” Process is mobile and can lower Calcium Hardness, TDS, Cyanuric Acid (CYA), salts, phosphates, nitrates, and waterborne diseases. We designed this system to give those with swimming pools a much better alternative to draining a pool by recycling the water and conserving 85% of it!

Just this past week, we scheduled a pool to be recycled because their chief complaint was high levels of Calcium Hardness and TDS. The following chemistry was causing issues to the pool and making it more challenging to take care of. Not to mention, their goal was to have better quality water in their swimming pool.

Initial Chemistry

Calcium Hardness – 1480 ppm

Total Dissolved Solids – 7669 ppm

CYA – 40 ppm

When dealing with calcium levels as high as they were in this swimming pool scaling would be a major concern. This is a common issue with swimming pools in Texas. After filtering this swimming pool with RO filtration, we were able to leave our customer with the following chemistry.

Calcium Hardness – 150 ppm

Total Dissolved Solids – 818 ppm

CYA – 0 ppm

The ending chemistry that was achieved with RO filtration is much better than our tap water. If you’re interested in learning more about how our mobile filtration can help you achieve a high quality of water for your swimming pool, give us a call at 817-481-7665.
