Good idea , alternative salts will not have any steriliseing ability so would keep temps low , reckon magnesium chloride might do the trick if chlorine availability is the issue.
Water companies no longer use elemental chlorine and now add Chloramine which benefits them in keeping pipes cleaner but is quite difficult to remove by the consumer.
