uv sterilzer

I haven’t had one in my 28 years.
 
Simply put... no. There are lots of opinions on the value of a UV, but I don't think you'll find many who think it is required. My personal opinion is that they can help with water clarity, keep down algae blooms, and eliminate viral pathogens. That's about all though.
 
I wouldn't say its a must to run on a reef tank, or any tank for that matter. But, and a big BUT... it's nice to have in case you need it.

I purchased one 7-8 months back to deal with a dino's, and left it running for 5 months after. Although it took care of my dinos in about 7-10 days I left it online. But took it offline at the end of the 2019 as I didn't feel I needed to run it any more.
 
Nowadays most people use UV light to sterilize bad/little good bacteria in their DT just in case they don't have quarantine system for coral and fish or to overcome unknown mistakes. You can lose all fish just because you received gift coral from friend or you bought infected fish from lfs.

However, UV is a must in quarantine system for sure.

UV will help to boost/reinforce the protection of fish and coral. why not having it?
 
I don't think it's a must have, but there are some issues (like certain strains of dinos) that it will help you with. I currently have one, but plan on taking it offline in another month.

Some people would not start a tank without one, others wait until an issue comes up and then get one, some never have an issue they think requires one, the rest think there is absolutely no proof they even work. That's kinda the beauty of reefing, many ways to do it...
 
i have a 57 watt so i connected it and still got cyano like crazy had to use chemiclean to get rid of it so i took it offline just trying to weigh the pros and cons
 
i do not have a qt tank as i have no space for it when my lfs store got his shipments i just took them straight from the shipping boxes i would acclimate them as soon as i got home
