Ok then maybe I'll run half salinity 1.020, for treating any flukes that survived prazipro and I'll add copper for anything that may be on them like velvet or ich that I can't see just to be sure. And hopefully at half salinity I won't have much of a pH problem but I'll get some buffer just to be safe.Just to clarify - that is the hyposalinity regimen for ich, that is lower than what is needed for Neobenedenia, and is more stressful. If you are battling both issues, then of course do that, but for Neo only, it is gentler on the fish to go with half salinity.
