Hyposalinity. When I've used QT tanks for treating various things, I've always slowly dropped salinity over a period of time. However, I've only QT'd fish that have needed treatment. I use temporary QT. It's great to have if you have the room and suggested,but, I don't use one. I do think that slamming a touchier fish into hypo would be sketchy. Some fish are able to handle higher levels of stress than others. |
