Our pool is supposed to be done and filled this weekend, but because it's a Wetedge application the SWG can't be started up for 28 days or so. The PB is supposed to start it up for us and then do the SWG start up later on. But I'd like to know as much as possible before then. Are there any special factors to consider when shifting over to a SWG? What about the chemistry after the SWG starts up?
