Thanks Folks.
As a point of reference, the Oklahoma Aquarium quarantines all new fish at 1.008 & 11ppt for 30-45 days. They claim they have seen greater results with Ick at this salinity.

"At the Oklahoma Aquarium, the use of hyposalinity has been modified from what is commonly used to a longer treatment. This treatment lasts throughout the time the fish are in quarantine, typically 30 to 45 days pending any disease occurrence. Salinity in the systems are also maintained at 11ppt. At this salinity, the Oklahoma Aquarium staff has seen a more rapid resolution of disease such as cryptocarion. The lowered salinity has also proven to be more consistent in preventing reoccurrence of a disease as well as new outbreaks.
When new acquisitions arrive at the quarantine facility, the main acclimation concerns are pH, temperature, and detoxifying the free ammonia. The acclimation process brings the salinity of the newly arrived fish down gradually although this is not the determining factor in introduction of the new acusitions. On several occasions we have received large numbers of fish at the same time all being introduced into an empty system. In these cases, the tank in which the new fish are being introduced to is acclimated to the newly arrived animals. The pH and temperature are adjusted down according to the arriving transport boxes. Salinity in the new tank is at 11ppt (1.008 SG) and the new arrivals are typically between 30 and 33ppt (1.023-1.027 SG). After adjusting pH, temperature, and detoxification of the ammonia, the animals are introduced into the tank. This is an immediate drop of 19 to 22ppt. These animals have shown no signs of shock or stress outside of what would be considered normal through shipping and handling. Quite often, species generally considered delicate and touchy to acclimate have done well in 11ppt and feed normally the next day. In the two years the quarantine facility has been in operation, only one case of cryptocarian has been seen. In this case, the salinity of the system was at 16ppt through an improper water change. Not only has cryptocarian been eliminated as a quarantine concern, the external trematode and protazoal infections have been reduced as well. The significance of holding all of the quarantine tanks at 11ppt has been the inability of these parasites to gain a foothold and reproduce. This has been valuable in preventing the recontamination of systems that might have occured if salinity was raised at some point through quarantine. No noticeable difference has been seen in internal parasitic infestations or bacterial disease. This was the expected result as the internal tissues would maintain a static osmolar concentration. More research is ongoing in these areas, although it is too soon to tell if any significant changes are occurring."
