The value of quarantining new fish gets displayed only when hobbyists encounter Marine Velvet in their reef tank. It is really unfortunate that many do not use their QTs.  
 
I have seen it too many times, and it is really hard to understand why a simple process is not practised. A 20 gallon tank, with a trickle filter, airstone/powerhead, ammonia detector (SeaChem made), some PVC (2" or 4" cut pieces, or Ts and elbows), heater, and a light (CFL). That is it. All for under 100$.
