Looking for a little info... My pool is in direct sunlight all day and I can not keep chlorine levels up. I bumped my CYA up to what I Expect to be 50ish after it totally dissolves. Pool looks good no problems but with my cya at that level, when I add chlorine I bring it up to about 8 ppm in order to keep it above the minimum level. If I leave my solar cover on most of the day or it is cloudy, I have no trouble keeping the chlorine level up. I know I saw a thread about this at one point but I can not seem to find it. But is it safe to swim at that level? How high a level can you safely swim without negative effects?
