I am trying to install an in ground pool in at the new home I am building. Since the land abutts conservation land the town of Rye is only allowing chemical free pools. I do not want to build a "living pond" and would rather build a conventional pool. The town has already turned down my application for an ecosmarte pool utilizing copper to clean. They claim the copper level would be too high and affect fish in streams. I need a solution. I was thinking of a large holding tank? My grandkids are counting on me to get this pool built. Thanks so much.
