I totally agree with the use of hyposalinity
if you can wait the 6 weeks, that is by far the best and safest treatment of ich.
what I do, empty out just over half the tank and fill it back up with fresh water...this should put you at about 1.010 which is where you want to be.
I have done this numerous times and there is no reason to bring the fish down slowly..just back up slowly over a 2 or 3 day period.

I will respectfully have to disagree.
I plunk fish into copper systems every time I bring fish in with little effect on 200 fish in them..with very little deaths.
it is the bringing the copper level up to the therapeutic level that is the dangerous part which is why I think seachem says do it over 48 hours..that is so you don't poison the fish with too much copper.
I totally agree that copper will kill fish..but as long as you keep it within the guidelines of seachem you should have little problems.
and adding cupramine will not effect the bacteria to where it will affect their ability to do their job..it is any live critters dying off within the live rock that may cause a small ammonia spike.
