Yes, it is one of the most important pieces of equipment in my system for keeping difficult corals. I believe it was useful for destroying bacteria and neutralizing toxins that prevented me from keeping Acroporas and Bird's Nest corals in the past. For fish, it was not important. I didn't notice any difference in ick before and after the UV. I had long bouts of ick even after running UV 24/7. In both cases, the ick eventually goes away on its own and fish are fine.
