I am new to the forum and I do not have a spa yet, but I plan to get one. I am reading a lot about the pool chemistry. Few years ago during a trip to Grand Canaria I came across a spa called Dead Sea Spa with high concentration of salt. I think that it might be a good idea to try it because I do not see the need for any additional sanitizing method. The reverse of the medal is: difficult to dispose of the saturated salt water. Is this a stupid idea? Please comment.
