I sure this have been brought up before - I was reading on line that you cannot have concrete deck and a Saltwater Pool.. the pool water will destroy the concrete in time...But if that was the case wouldn't the sidewalks and roads be just dust and rubble... Is there an issue with pool ladders and pumps and stuff... We used to have an Intex pool with a SWG and it was great.. We moved and we have an old 1960's concrete pool with vinyl liner....I don't want to make a costly mistake switching to saltwater...
