I'm a bit confused, is there any difference between a fresh water and saltwater pump. I was at a LFS to buy a pump and the person who helped me said that the spesific pump is saltwater ready, i asked him to explain but he couldn't tell me. Has it got something to do with the shaft or casing. I know the pumps i use has ceramic impellers but besides that is there something else i'm missing.
