I've used a chlorine generator now for two summers and am into my second winter. The water feels softer and silkier and I have saved time dealing with chlorine during the warm season. However, things that I did not know up front are that there would be a large acid demand. The chlorine generation process raises the pH of the water and you need to periodically add acid to keep the pH in the desirable range. Also, when the water temperature gets down in the 50's the chlorine generator does not work. You will need to add chlorine in the winter, although way less than needed in the summer.

I am also worried about corrosion. Within two months of installing the system, a screw on a faucet became corroded. I wonder if there are other parts of my system that may not be corrosion resistant. In particular, I worry about rebar in the pool shell.
