Where is my chlorine going?

[goosegunner]

So when you maintain this high chlorine level is your pool out of service for swimmers for 2 weeks then?

Again what about your liner?

I just found a small 1/4" cut in our 5 year old liner. When I went to the pool store to get patch glue the woman at the pool store told me to watch the Cl levels because too high will cause that. I have never ran with high Cl other than shock.

"too high" depends on the level of CYA in your water--stabilizer. With none, vinyl can tolerate up to 15ppm of free chlorine. But with stabilizer slowing down the chlorine, you can go higher--see the Best Guess table for the shock levels--they apply to vinyl pools.
