I got a new Maytronics robot this year and I opened my pool today. they put in 9 gallons of chlorine (not sure why) and my FC is 25! anyway, I read that I can only use the robot in max 4 FC - I mean, I have to keep mine around 6 usually because I have an SWG. I assume that is ok, but is it ok to put it in at 25? I really need it, I have a lot of trees!
