I soak their food in Selcon about 3-4 times a week.  Garlic, no.  I feed a mix of silversides, prawns with shell, blue crab and smelts.  Occassionally I give the triggers an algae wafer because they seem to like it so. 
 
So far I seem to have 'gotten away' with treating the tank for ick the first time, though some of the green growth on the rocks did die back a bit.  The hermit crabs and cowrie snail are still alive too, so no harm done it seems.  Though maybe no good.  Would something like Melafix do any good? 
 
I just checked the nitrite again (because you asked), and it is negative.  Which is what is almost always is. 
 
He's quite a voracious eater, I wonder if he's stressed because I'm not feeding him enough?  Although if I fee HIM more than once a day I have to feed everyone more than once.
