ANd after a few weeks of swiiming in the pool I asked my brother who has swam in the same pool using pool store chemicals, how his eyes were and other things he said, when he swims in the pool now it fills cleaner and his eyes dont sting as much. Now my question if I dont sound too stupid, is the cleaner term hold any weight, does the BBB method cause less irratation, and less residue??? Dont realy care cause I am BBB for life!!!
