Did my first SLAM, heater running so I could get in and brush, etc. FC at slam level was 13. I just read where it’s bad for heaters? I have a Coates electric heater. I’m at the end of SLAM but hesitant to turn off heater now, wouldn’t that just leave the high chlorine water sitting in it? Should I just let it keep running as the FC comes down? This pool was spendy and it’s only a year old, can’t afford to screw it up already.
