Newbie here! Been lurking for a month or so as I am in the process of building my pool and am a new pool owner wanting to make sure I'm not being taken for a ride! After reading the thread on chemical free pools in the stickies, I'm a little nervous. My PB will be installing a Bioguard Mineral Springs automatic chlorinator with a sand filter (TR50 Pac Fab), and a 3/4 HP Pac Fab pump. Am I reading this correctly that this chlorinator will put metals in my pool? Does this equipment sound correct? Thanks in advance for any advice!!
