I am a new pool owner and have a question about our SWG. We setup the pool yesterday and hooked up the filter and SWG. We put salt in the pool and have been running the filter and I no longer see any sand at the bottom of the pool. The SWG directions say run filter for 24 hours for the salt to dissolve before turning on the SWG. Since I no longer see any salt when I brush the pool, is it okay to turn on the SWG? Thanks for any answers.
