We are in the process of building a pool. Right now our pool builder will be providing the Nature 2 System along with a DEL Ozone generator. I know the Nature 2 system will still require the chlorine but I want to try to be as chlorine free as possible. I have a family member with the HealthCare system and they love it. They have had it for many years without any problems. I know you can't be 100% chlorine free but I want the best for my family. Any advice??? Any other options available? I am so torn...they start digging next week.
