Normally since I have a SWCG I wouldn't be asking this, but I've noticed lately I'm having to run my SWCG at a higher setting than usual; right now it's set at 80% with the pump running 12 hours a day to maintain 5-6ppm CL (CYA is at 70-80ppm).

Since I'm entering the 7th season with the same cell, I suspect it's showing it's age and may fail sometime this summer.

I'm concerned that my cell may fail while I'm away for a week and I'll come home to a green pool. Is there something I can do before I leave to assure this won't happen? Unfortunately I don't know anyone who can check on it while I'm gone.

I'm a bit hesitant to go ahead and buy a new cell since the warranty clock will start ticking and it's possible the old cell may hang in there all season.

I thought maybe bring CL up to shock level just before I leave while leaving the SWCG running at normal level while I'm gone? If I do that do I run the risk of coming home to a bleached out liner?

Another thought was to just add a quart of 60% polyquat before I leave and leave the CL level at normal (5-6ppm).

I appreciate any suggestions.
