I recently talked to a pool saleman about pool systems, having frequently been asked at open houses whether or not the pool is "saline" vs "chlorine, I had a few questions...
First of all, I didn't realize that a pool system could easily be converted from chlorine to saline and that the cost was fairly reasonable. The converter itself costs between $1,200 to $1,500 and another $300 to $500 for the installation. Maintaining a saline system is much easier apparently and less expensive as well with the elimination of having to add chlorine on a regular basis.
Some of the benefits are the elimination of caustic chemicals that can irritate your eyes and skin, the water has a smoother feel, there's no chemical storage to worry about, and the saline system gives the water a more clean and sparkling appearance. Living in Naples, FL where pools are the norm, I thought you might find this interesting.
