It has been my experience that 4 weeks is enough to rid a tank of ICH, if it is kept fishless throughout that entire preiod. Hyposalinity works but 1.0075 is far too low. 1.015 to 1.010, shoot for the middle of the road there (in the quarentine, not the display tank!)
Regards
PS: I've had success with cupramine, also fromalin and malachite green |
