We've never seen any evidence that they do anything but cause trouble. Keep in mind, that's in comparison to a BBB operated pool.

With the hit-or-miss system most home owners use under instruction from pool stores, the mineral cartridge creates a sort of belt-and-suspenders approach to keeping pants up. It's just that it's a rotten leather belt, backed up by a pair of suspenders that are hanging by a thread! We think it's better to ditch the suspenders, and use a good belt, so to speak.

My illustration may not be clear, so I'll state it differently.

The pool-store chemical treatment method produces a world of problems AND frequently leads to algae. A mineral system creates a weakly algicidal residue, that can help a badly managed pool turn green fewer times. We thing the better option -- easier, cheaper, more effective -- is to use a GOOD management system that doesn't need to be backed up by a weakly algicidal mineral system that brings a new set of problems along with it.

Regarding your specific system, without model numbers I can't be completely sure, but as a rule, you can disable them, try life without it, and revert to the 'as-built' process with no problems (other than the ones inherent to the mineral process).
