I'd personally be more worried that the copper in the malachite green would 
affect your plants.  I used quinine sulfate way back when I was just getting 
started, and found it to be a good cure for ich though.  I haven't used it with 
plants.  I have used "Maracide (TM)" in my big tank when I had a widespread 
outbreak of ich.  It's an aniline green mixture that didn't negatively affect 
my plants as far as I could tell.  I also raised the tank temperature to 84F 
from 82F.  The ich was gone in four days.  It didn't negatively affect my 
cardinals or my cory either, as far as I could tell.  Note:  One bottle of 
Maracide is only enough for a 35 gallon tank.

If you have a sponge in your big tank, use it for part of the bio-filter on the 
quarantine tank.  If your big tank is heavily planted, you probably don't need 
much of a bio-filter.  For peace of mind, replace the sponge from the big tank 
with another one.  If you don't have a sponge, you might be able to use a few 
handfuls of stem plants to help start the nitrogen reduction.  If you use 
plants, supplemental CO2 might help them out.

Just thoughts, really.  I wound up using the Maracide in my main tank and 
didn't have any problems.
