As title says, I'm away working so she had to open the pool. I told her to add the cya in skimmer but she said it came out of the return line. So I got her to check the valve and she had it on the wrong setting.
Now my question is what happens to the cya level? Should I get her to add more in or will it still be effective?
Thanks
