I had done Hypo Salinity earlier this year to rid of ICH and it helped getting rid of ICH with no dead fish as a result of ICH. The fish seemed to be healthy and ate/moved properly for a month and half while in Hpyo Salinity Environment (Right around 1.009). My Question is why has any one not tried keeping fish in Hypo all the time if it eliminates ICH with no room for return and also fish seem to be completely fine in it? Has anyone tried this for longer time or does anyone know of any long term side effects?
