LFS recommends UV sterilizer over skimmer...which is it??

Hi, I've got an empty 50 gallon acrylic tank that I'm planning to put together as FOWLR. I plan to put in a clown or two, a royal gramma, a pair of blue damsels, a hawkfish, maybe a flame angel, but no tangs. I'd prefer not to go nuts right away and build a sump, but to take it slow and upgrade to that someday. I also would like to minimize the amount of equipment I buy, partly for cost and partly for noise (my wife is reluctant about this fish tank because she hates trickling noises, so I need to start small and win her over).
I've been to a few LFS's around north Phoenix and there is one that stands out as really nice--it's clean, has beautiful tanks and healthy fish...it seems the most professional. They've been in business for 10 years and they have a 2-week fish guarantee. The weird thing is, they (this being three separate associates who all seem to be fish enthusiasts and have some knowledge of the hobby) have told me that if I'm deciding between a skimmer and a UV sterilizer, that the sterilizer will give more benefit to the health of the fish than a skimmer.
This is driving me nuts because all the opinion I’ve gathered from reading several books (recent ones such as Michael Paletta's book) and from conversations here and on a couple of other forums seem to agree that the skimmer is the more necessary, or at least highly advised, piece of equipment for a beginner.
Here is the LFS' reasoning. They say I should be using a canister to mechanically filter out the solids and the only thing left to worry about is the parasites and stuff that could cause ich, etc. I asked them, “What about the chemicals and whatever other gunk a skimmer would get--don't those need to be removed, and the UV sterilizer won't do anything about them?" I can't remember the exact response but it was something like "Well yes, if you had corals and other more sensitive things then you'd need a skimmer, but fish-only tanks are ok without one".
They point out that every one of their tanks runs a UV sterilizer. They also pointed to a 20-gallon tank with seahorses and a lot of plants inside that only has a sterilizer and no skimmer (they admitted when pressed that the rest of their tanks are on common systems that are skimmed).
So please respond with your sound knowledge and experience—please set me straight on which piece of equipment will give me a higher chance of success, if I am to purchase only one at this time. Extra points to you if you are speaking from years of personal experience, and not just “what you’ve heard” or “what you understand”. Because I’m already there—and my “understanding” is being challenged by this shop!

Here is a recent thread explaining exactly what you are needing to know.
https://forums.saltwaterfish.com/t/305160/protein-skimmer-vs-uv

IMO skimming in a new tank is much more important than UV. Although you are running a canister (another issue with canisters is it will be a PAIN in the you know what to change out the media on a canister, i would suggest a refuge) from my understanding skimmers are much more effective. Unless you are running an overflow which will be taking the gunk off the top of the tank, things like oils (insert a million other things) tend to reside at the top of the tank. This is why you get the "oily" look on the surface of some tanks, b/c the crud resides at the top most of the time. So a skimmer is most effective is removing this stuff.

There isn't much you can do about the accumulation of the stuff that a skimmer will take out of the water, but you can almost completely prevent the arrival of the infectious organisms that a UV unit will kill. So get a 10 gallon tank and make yourself a quarantine tank, and religiously quarantine everything that goes into your display and you probably won't ever need the UV protection.

Wecome to the boards. I agree the UV is NOT the way to go.If your LFS is saying that is better maybe look for another shop.

What exactly is the uv doing for the tanks? It's not going to filter out parasites unless run extremely slowly and still would miss most of the free floating and all of parasites in other stages. A skimmer is going to remove organics and help keep nitrates down, a huge issue in a folwr tank. I would go for a skimmer anyday.

K guys, thank you. I did read that other thread that you linked, Lex. I posted my own question because that discussion addresses the difference between the two but didn't give me an answer as to why someone is telling me the UV sterilizer will have a more significant benefit than a skimmer.
I have to say that based on everything I'm reading, I'm skeptical of this shop's advice, but they seem genuine in their opinion. However, it's one opinion versus a consensus of many. so I will probably go with the skimmer.
Additional opinions welcome, I will keep checking back...especially if there is anyone out there who agrees with this shop, I would especially like to hear from you!!

My thought would be if someone agrees with this shop. They too should be suspect as to having any true expertise in this field.
Again Welcome and read all you can on the forum, there are some truly talented folks here ( not I) I just need the typing therapy. Good Luck........

skimmer pulls organics out of the water
UV kills everything in the water that passes through it.
I would only use a UV in a tank that is FO and not a reef because alot of what it will kill of is used by the corals and microfauna of the tank.

Exactly true. UV's are highly over rated. They do serve a purpose, but the same purpose can be achieved with quarantining new purchases. Get the skimmer.

Nice...thanks. I'm pretty much decided to get the skimmer and just smile and nod if they say I made the wrong decision.

And I might keep looking around for other LFSs, just to do price checks n stuff.

Get a skimmer but make sure you get a good name brand(euroreef,ASM,Octopus)or you will be buying a new one in short order

Bought the AquaC remora...seems great so far. Making foam, not too loud...but no gunk yet, just water. I'm just starting to cycle with live rock that was in an established tank previously but that I think I injured by keeping it in water that was too warm for about 24 hrs. I measured ammonia at 1.5 the other night, with no nitrites and only a little nitrates (possibly zero?). Can't wait to start seeing that gunk! (Gee am I some kinda wierdo?
)

Hey I am glad you are liking the skimmer so far. That is the same model (AquaC Remora w/1200 MJ PH) i am planning to get as i plan for my 20g.
BTW, I am in N. Phoenix and I think I know of the LFS you've been talking about...did you end up getting your skimmer from them or some diff LFS around town? I am curious since I am still shopping for mine and looking for a decent deal.

You can look at your water, with the fish happily (hopefull!) swimming around in a clean and balanced tank and then you look in the collection cup and see all the gunk the skimmer is pulling out and is't whoa, where did that dark and nasty stuff come from? My tank looks real clean. Once your skimmer starts working, you will be very glad you got it! It can tak awhile for it to start working.

AtrialFib22:
I found the lowest priced "buy it now" deal on a certain website and I only saved about $15 from the store's price...if I recall they are asking $179.
They're not a bad place at all, I haven't found any places with better fish, corals, a cleaner shop or more knowledgeable employees yet.
They just kinda threw me with this one piece of advice. Ehh, whatever.

2 pieces of advice.........
First buy the skimmer before the UV, and 2. Find a new fish store with info like that.
