Newbie here and I plan to install a GAC backwashing system and a water softening system. I was wondering what the experts think about about TAC water softeners which I understand do no require salt. Do they perform as well as the salt-based water softeners? I did a board search and didn't find much discussion about this. Also, our local water district uses chloramines to treat the water. I was researching online, I read somewhere that a Centaur filter is the only one that removes chloramines - is this accurate? If so, is this the only one I should consider?
