Well probably because hyposalinity only work for ich, nothing else. It does nothing for velvet. Also I have read of resistant strain of ich and for those only copper will work.
Sometime copper is the only way to save fish but I would use it as a last resort and if in case of velvet. Velvet kill so fast that even copper need to be started early in the disease.

Good call. I try to get all new comers with Prazi...makes a big difference for some of them. |
