PLEASE HELP - Can I close my pool with free chlorine at 13 ppm?

[lcd98]

I am having my pool company close my pool tomorrow. I originally planned to have them do the chemicals because it is only my second closing and I am still learning. Then I looked at JasonLion's closing post and decided it would be better for me to do my own chemicals so that I could put some space between shocking and adding algaecide (which the pool company does at the same time). So I shocked it to 14 ppm FC yesterday (CYA was 35). This morning it was about 12.5 FC and this evening it went back up to 13 FC (probably because I still had the SWG running). I called the pool company to let them know I was doing my own chemicals and they said they usually don't close pools over 5 ppm FC. They also said to keep my pool filter on to see if the chlorine would go down. Since it went up by this evening, I shut off the SWG and left the filter running on low. Is it okay for me to close tomorrow with such high FC levels? Will the chlorine dissipate after closing? I have a fiberglass pool and I am concerned that it will damage the surface. Thanks so much for your time.

It'll dissipate--just take longer do it. Go ahead and close. Filtering your water more has nothing to do with lowering your FC.

Do you think the closer is going to test your water? Probably not. Choose TFP.

I presume the tech will test the water.

Agreed, which is why I thought it would be better to do it myself. Thank you.

I close with my pool at SLAM level which for me is 16. They do pull a sample but I never hear back from my pool company after they pull out of the driveway.

Do you have a contract with them that guarantees against damage? Mine fully guarantees my pipes and equipment against freeze damage. They let me do all the chemicals.

Sorry. Wrong thread.

Thanks to all for your input. They wound up running late and coming the next day. By then, my FC was down to 7. I don't have a contract with an explicit guarantee. I will look into that for next year. Also, FWIW, they did test the water even though I did my own chemicals. Thanks again and have a nice weekend.

They always pull a sample at opening and closing. I do all my own chemicals as well.
