Hello! I really need your help. I have a 120 gallons + a 30 gallons sump. Since 2 week my fish have developed oodinium. Since that time they are in hyposalinity at 1.009. I have already lost 5 fish including my beatiful majestic Angel. My fish breathe quickly and shake their head. Do you think a Cupramine treatment is a good idea during hyposalinity? Or do you have any other idea, Thank you!
