Where is my chlorine going?

Voldaddy - How did your liner survive the barage of chlorine?

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.

Well my chlorine has been dropping but not to 0 it goes down to 1 & 2 and holds there that's a big improvement. Maybe what ever is causing the problem is just about gone.

I did a full test of the chemicals and found my ph dropped to 7.2 and my th went to 200 but is holding chlorine between 1 & 2.

With a cya level of 45, letting your chlorine level drop to 1-2 is not adequate to keep algae away. You have to maintain the cl between 3-6 all the time. If you let it drop below that, it is an open invitation to algae. I would shock it back up just to make sure that something isn't starting as a result of the low cl you have had.

Your right my chlorine is too low but after shocking it the chlorine was dropping to 0 and now it drops to 1 & 2 so for me that's a big improvement. This morning it any dropped to 3 so it's getting better. I still don't what is causing the large chlorine consumption but it does seem to be getting better. at this rate it should be holding a good number by the end of the season. So far I have used three times the chlorine I used all last year.

My pool is finally holding the chlorine level at 6. Since I opened my pool I have been dumping tons of chlorine in my pool and it would disappear then it started to rise a little every few days and now it's finally holding where it should. Thanks for all the help.
