I have had my salt pool for over nine years. I have no unusual corrosion over that time. However I do have brick coping, tile water line and concrete pavers. In the nine years I have replaced the salt cell once, and the pump motor (just the motor not the entire pump) twice. I also have a solar heater which has not given me any problems. Once set up correctly, a salt pool CAN be left unattended for two weeks at a time (vacation anyone?).
