Initial Cost

• The initial cost of a salt generator can be high--as much as $2,500.
  
  

Requirements

• Salt generators require knowledge of cleaning procedures in order to keep them in good working condition. Salt water pool owners must also know how to maintain the correct balance of chemicals in the pool.
  
  

Warning

• Salt is corrosive and those that have flagstone may want to reconsider, since damage can be caused by the salt water.
  
  

Considerations

• Salt generators may not produce enough chlorine if the pool filter does not run long enough, if there are phosphates in the water or the pool is heavily used. Chlorine is needed in order to keep the pool sanitized.
  
  

Replacement Cost

• Salt water generators last on average three to five years before they need to be replaced.
