How can you guys say certain treatments are useless on ich? Where are you getting this information from?
Garlic is not meant to be an "anti-ich" treatment. It is a method to entice fish to continue to eat, not kill the ich. Vitamin-C, IMO, can allow fish and inverts to recover from injuries, infections, parasites, etc. quicker. Fish recover from ich infections in the wild, and garlic and vitamin-C can be considered two "natural cures".
The prefix "hypo" refers to anything in a lesser concentration than normal... 1.009 is not a magic number. A range of 1.013 to 1.010 can also be effective. Also, hyposalinity is really only effective on the early stages of ich's "life cycle" and mature cysts are usually not effected. From experience I've found waterwater dips to be the most effective and quickest treatment for mature ich cysts on fish, but it is a poor treatment for anything other than mature ich.
It looks like you don't agree Freed. Why do you say freshwater dips don't do anything to kill ich?
In the end, I would treat with cupramine and skip the hyposalinity. I definitely wouldn't do both treatments at the same time. Copper is the more effective and quicker killer of ich, in all stages of its life cycle, unlike a hyposalinty treatment.
