Hello everybody, I am begining hyposalinity in my 100 gal tank because my new yellow tang has black ich (flukes) on him. My tank is a fish-only one and has been running for about two years. All of my fish are hardy species. My question is this: Does hyposalinity stress fish? I would like to add the final two fish now, during my hypo treatment, so that any parasites brought in on them will be killed without requiring another hypo treatment. Do you think that this would this be a wise move? Thanks.
