I'm currently keeping my FC at 8 ppm, since my cya is 70. I understand it is higher than others because my cya is on the higher side. Is this level safe for us though? I have young kids 18 months and 4 years and I just want to be sure this isn't going to be too harsh for their skin. I'm using 6% bleach and have stopped using pucks as of about three weeks ago. Am I better off replacing water and bringing cya level down so that I can maintain a lower FC level or are things fine the way they are?
