I just added a large sailfin tang to my tank last night, by the time I got him home and in the tank, he was covered in ich. My tank is very clean, high oxygen, and lots to eat. Already the ich is all but vanished, and I don't suspect I'll see it again unless I mess something up in the tank.
I don't use QT, I don't treat (we won't get into the garlic thing here ), I just give the fish a healthy, happy home. This approach has worked wonderfully for 10 yrs + now.
If your thought is to use UV to fight ich, IMO, save your money for something else.

I agree completely and use the same approach. However in my experience younger tanks or one with lower water quality can benefit from a UV. It can be a useful tool in controlling disease when introducing many fish in a short time. They can also reduce algae growth and increase water clarity. They do however require more maintenance than most people care to give them.

I thought i'd try one to help with that algae film that required daily glass cleaning.I know about the killing good things,so it's on a timer,running 10 hrs in the daytime.After using for less than a week i see....my glass is clean maybe cleaning it every 2nd day now.

Just thought I would mention that my ich covered Tang from Thursday now has absolutely no ich at all, with no intervention from me.
