UV normally only works part of the time and is a big expense that IMO, isn't worth the money.
The problem being not all of the parasitic stages of the ich go through the UV and the fish, remaining stressed, still presents visible signs of the ich.
You DO however, lower the level of inherent zooplankton that the corals feed on as some of it goes through the UV and is killed off along with the portion of parasites that are killed.
IMO the best answer is STILL to remove the source of the stress.
