How Do I Lower Calcium Hardness In My Swimming Pool?

If you live in the Southwest U.S., and own a swimming pool, it’s a guarantee that you will deal with calcium hardness in your swimming pool water. Why? It’s simple, calcium hardness is extremely high in tap water and as water evaporates in your swimming pool, the hardness minerals stay behind and gradually get higher and higher. When dealing with proper chemistry in a swimming pool, your ideal calcium hardness is between 200-400 parts per million (ppm). Depending on where you live, calcium hardness coming out of the tap can be 500ppm and higher. This is a major issue in many parts of the country especially where water is at a premium. With that said, the typical answer would be to drain a swimming pool and fill it up with 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, you can now recycle your swimming pool water using our mobile filtration system. Our “Puripool” Process is mobile and can lower calcium hardness levels as well as other nagging issues like total dissolved solids, cyanuric acid and many more. We designed this system to give those with swimming pools an alternative to draining by recycling it and conserving 85% of the water.

Last week, we scheduled a pool to be recycled because their chief complaint was high calcium hardness levels. The following chemistry was causing issues to the pool and making it more challenging to take care of. Not to mention, they couldn’t imagine wasting 20,000 gallons of water.

Initial Chemistry:

Total Dissolved Solids – 6468ppm

Calcium Hardness – 1250ppm

Cyanuric Acid – 60ppm

After recycling the swimming pool water with our mobile filtration system for 12 hours and conserving 85% of the water, we left them with…..

Ending Chemistry:

Total Dissolved Solids – 743ppm

Calcium Hardness – 170ppm

Cyanuric Acid – 0ppm

The biggest takeaways from our system are not only water conservation but giving our customers better water than they would get out of the tap, which also saves time and money. Remember, Don’t Drain Your Swimming Pool, Puripool!!
