My perma salt system is 1yr old. Last year I ran into the problem of having too much copper. (After 4 days of running it on level 4.) I drained down, refilled, drained down, refilled, etc, with no difference. So I turned the system off. This year I decided to check my tap water. It already has the copper in it that the perma-salt system needs. If I turn the chamber off, will the copper in my tap water kill the bacteria? Is the chamber useless to me? Help, please.
