I disagree that it is a must. UV
's do not get everything. Ich is more either on/in the fish, or dropping off into sand/rock. UV
can't kill what does not pass through it and in the case of Ich, that is a relatively small amount.
They also need proper water flow, changing bulbs on schedule and cleaning, etc. I had one years ago and sold it. Helped with algae a little, but still got stuff like Ich (back in my non-QT days).
Proper diet and pristine water goes a long way, but it only takes adding a fish with something like MV to wipe out a tank in a matter of days. Everyone tends to focus on Ich, but there are nastier things out there.
