read about salt treatment from ich, anyone tried before?
As a treatment for ich and some other protozoa, the infested fish should be dipped in salt water at 30 ppt (or 3.0 ppm, which is the salinity of seawater), for 30 seconds up to several minutes, or until the fish rolls on its side. At that time, the fish should be placed back in its normal salinity water. To mix this solution, use tank water and dissolve in 30 teaspoons of salt per gallon, then place the fish into this water, monitoring it the entire time. This is then repeated once daily for three treatments, with a 30-70 % tank water change between treatments. This treatment is different from most of the others, in that it is used to treat the organisms in the skin of the fish, and not the free-living stages found in the fish tank. Lower doses may be used as a continuous bath in the fish tank. At 5-10 ppt (0.5-1.0 ppm), fish can survive for several hours to several days, and this will effectively kill the ich organisms. At 4-5 ppt (0.4-0.5 ppm), freshwater fish can live for up to four weeks, and this will also break the ich life cycle. A bath of 4-5 ppt will effectively kill anchorworms and lice. It must be noted that a salinity of 5 ppt or greater will usually kill live plants. One ppt= 1 tsp/gallon, three ppt=1 tbsp/gallon. One pound/100 gallon pond water.

sounds interesting but scary.
