Treat water or drain?

Hi All,
I have the same exact problem...
Can I ask though if it is ok to drain 1/2 the pool with a vinyl liner?
I thought I read somewhere that was bad for the liner.

Also...if you do drain 1/2 of pool is it best to shock remaining water before adding new water (to kill algae)?

Thanks.

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.

Joe,

AS long as you only drain about half your pool, the liner will be fine. As you drain, observe for any wrinkling or movement of the liner that might not come out when the water refills. If you observe something you don't like, stop at that point just to be safe.

I would suggest you refill completely and then shock. Your pump probably won't circulate once you drain below the skimmers. Additionally, you'll only have to shock once instead of twice

Thanks Dave. Good point. I'll try that.
Thanks again.
