Does hyposalinity really work for ich?

[marie]

I have treated my achilles and my 2 potters with cupramine and all 3 are still alive to tell the tale.....
I tried using freshwater treatments to treat MV on my achilles but after less then 90sec in the fresh water I thought I killed him and just couldn't go through it again

I only use hyposalinity on new fish if they have no signs of parasites, if I see anything suspicious I go straight to cupramine treatments


*Edit*But then I've become rather anal about keeping ich out of my display, my achilles has never had any ich since quarantine and I plan to keep him that way
