They opened my brand new pool a week ago. Water is crystal clear. SWG has just started getting warm enough to run. Test strip says high alkalinity and 0 free chlorine. Should I wait longer to let pool settle? Or should I do the backwash, add DE and then add stabilizer? Can I pour the DE in and then the stabilizer or should I give time in between? Thank you! I have never owned a pool, this is new to me.
