is salt water pump the best for above ground pool


I assume you are talking about a salt chlorine generator that converts the salt in your pool to available chlorine and then back to salt. This can be a very effective system and can be low maintenance. However, you have to consider the long term cost as well. Buying the generator can be expensive and replacing the cell is also expensive. If you take great care of the cell, it is generally expected to last 3 to 5 years. Therefore, consider the full cost compared to regular chlorine maintenance.
