I'm knew here. I have tried to do a search on this forum for this, but didn't see anything that full answered my question. I was thinking about getting a Intex Krystal Clear Saltwater System for my new intex ultra 18'x4' above ground pool. My question is if I would buy this does it mean I would not need to use any other chemicals? Also is this something a beginner like me would even want? Any advise will be appreciated.
