Beerman touched on it but I think that it needs to be made clear. We dont recomend putting a salt system on an above ground pool unless it has composite walls and bottom track. A typical above ground has painted steel or aluminum walls that are held at the bottom by a U channel. water that splashes out of the pool runs down the walls fills the track and evaporates. It keeps doing this untill there is a very high and corrosive salt level in the channel and the pool corrodes.
