I have a brand new pool I just installed and I wanted an SWG. The pool builder installed a Zodiac Nature2 Fusion Soft which has a mineral cartridge with it. My daughters are all blond and it is turning their hair green. I have read countless articles on here about this and the use of minerals. My question is I have also seen people say that they have stopped using their mineral cartridge on this system and just used the SWG portion of it. I want to do this but I don't see a way to get rid of the mineral cartridge as it makes up the center part of the cover. How do I stop using the mineral cartridge and just use the SWG portion of the chlorinator?
