So my vinyl IGP pool build is soooo behind due to weather. Has been sitting for a week with water, but no filtering. SWG will not be hooked up for a few more days and water is getting a bit nasty looking. Should it be shocked with something prior to SWG hookup? and if so, what should be used. I assume that even though city water that chlorine is gone.
(SWG is a Hayward w/ T-Cell-15)
