Hi, I remember a thread before the crash that dealt with a guy that had a weekend home with a pool. Since he was only there on the weekend he was running a high cya pool and basically shocking before he went home on Sunday. The chlorine lasted all week and he was good to go when he got there on friday. I also remember there was some thought that this maybe an ok way to run pools. Add chlorine once a week and keep it high enough so it doesn't go below the minimum on the best guess chart. Just a thought.
