i didn't think anyone was going to reply.
so basically just close as i was instructed by the pool person and not worry about blowing out the lines?

Carl D. had told me in an earlier post to shock to 15 and add poly quat and wait 24 hours, then shock again and close. does that mean close right after it reaches 15 the second time? my pool person never put a gizmo in the skimmer, only thing ever put there was one of the empty plastic bottles of shock. should i do that?

thanks for your reply and help.
