Be carefull never to put copper in your display tank, and carbon will NOT remove copper! There is a product I think by Seachem that is supposed to remove copper but it is very hard to remove so never put that in your display or you will not be able to put any invertebrates, probably for a very very long time.

The danger with hyposalinity is this...if you put your fish right away in hyposalinity and it turns out to be marine velvet, then you must raise the salinity to treat with copper (it is not good to treat copper with hypo) and raising the salinity must be very very slow so marine velvet would wipe out your fish before you get the chance to have the right salinity to treat.

This is why a positive ID is important. If it is ick, then treat with hypo, if it is marine velvet treat with copper or preferably chloroquinine right away. Hyposalinity don't do a think for velvet.

For broklynella then it's Seachem Paraguard. In fact I would start my quarantine with full salinity and Paraguard, and only do hyposalinity when absolutely certain it's ick.
