Saltwater pool systems are great additions to an above ground pool setup. Skin and eye irritation that can be caused by chlorine become a thing of the past with a saltwater pool filtration addition. It is important to note that saltwater systems should not be used with steel walled above ground pool because of the salt water’s tendency to corrode steel. Resin or aluminum wall above ground pools handle salt water pool systems much better than steel walled above ground pool.
