it is a food but ya its good to get rid of it. its not life ending if not. i didnt for years and my grows where just fine. yes it helps the pH, and i dont know of anything in the foods other than organics that it will kill off. most cities dont use it anymore anyways, they use chloramines and no sitting out gets rid of that, and R/O machines only remove a bit of it. need an upgrade filter to remove more of it.
