Thanks to Beth, I have been using hyposalinity in a QT tank with success, but have also been curious abouut the freshwater dip method. What is considered "fresh water" I assume r/O water with balanced ph, but what salinity? no salinity or low salinity? Also how long do you dip them safely? I also use a 36 watt uv 24 hours in my tank. I have 4 shrimp, 3 starfish, some snails and hermits and a small lobster, besides the fish, but no corals or anenomes, just live rock. I beleive the uv does help control the spread of ick and certainly other bacterrial diseases. If nothing else, it controls unwanted algae, at least in my tank. I feed the fish food which has been soaked in both garlic and vitamin c, and throw in some vitamin c in the tank as well periodically. What about vitamin c. Some people endorse this very strongly in order to help the fish establish a good immune system? So all in all, my ich battlers are, uv, vitamine c, garlic, cleaner shrimp, cleaner wrasses, temp of 76, and initially qt in hypo....but most times I can not do this for an entire month. Usually at best a couple of weeks.
