chlorine level keeps rising

Great!

So after returning from our camping trip, the FC was 18.0 ppm, pH was 7.0, and CYA was less than 40. I added 1 cup of dichlor Thursday afternoon,just prior to leaving.
Our solar cover has been on continuously. I just took it off,in hopes that the sun will help to lower the FC.
I read about sodium thiosulfate, my children and I want to be able to swim today. What can I do so we can swim safely?

I did add 1 cup of borax last night to raise the pH level.

I'd swim in a shock level pool - with an old bathing suit. Shower (or hose) the pool water off as soon as you get out.

I'm with Big Dave. I would definately be swimming tonight. Chlorine level of 11.5 is swimmable. Especially when it is nice and hot out

Well we went for it and swam in the pool. Actually, I mainly cleaned the pool while my children swam and played. It felt great to finally be able to enjoy our pool.

Great! That is the whole reason for having a pool! :)
