Salt vs. Mineral

And "poor bactericide" means that it does not kill nor even inhibit fecal bacteria at all and only kills non-fecal bacteria slowly (except for Legionella). See this post for technical details. If you absolutely have to use a metal ion system and don't care about staining or blond hair turning greenish, then at least use a copper/silver ion combination since that will at least prevent uncontrolled bacterial growth of even fecal bacteria though you still won't have any reasonable protection against viruses or protozoa.

Run, do not walk, as fast and as far away from that "pool professional" as you can! He will get you and your family sick.

Instead, it sound like your SWCG needs repair. Are you sure your salt level in your pool water is correct? If it isn't, correct it. If it is, well, certain items on SWCGs do fail over time and need repair or replacement.

Most likely your salt cell has failed and needs to be replaced. The average life of a salt cell is about 5 years. Run and do not walk away from the 'mineral' system!
