Most often swimsuit damage (like hair and skin damage) is caused by improperly chlorinated pool water. If there is too little chlorine in the water you get chloramines (or combined- chlorines) forming - and these are the things which have a strong chlorine odor and are the casue of pretty much everything chlorine gets the blame for. If the water is shocked these combined chlorines will be removed. If the water is kept properly chlorinated and shocked as required I don't think you will see the fabric damage. A saline system in fact shocks the water constantly and you will rarely find combined-chlorine in a pool using the salt water system as the means of purification.
