Are canister filters okay for Fowlr tanks? I’m hearing a lot about Sumps being the thing for reef tanks. Any pros or cons? I definitely want one with one of those UV lights.

Yes you can use a canister filter for fowlr tanks. You can also use them with reef tanks if you want/know what you are doing.Are canister filters okay for Fowlr tanks? I’m hearing a lot about Sumps being the thing for reef tanks. Any pros or cons? I definitely want one with one of those UV lights.
Yea I am, I’ve been doing more research about sumps but I’m seeing that they’re more so for reef tanks. My Fowlr really wouldn’t need all that extraness, BUT I was also thinking about upgrading to at least a 125g so I heard you need a sump for thatYes you can use a canister filter for fowlr tanks.

I would never use a canister filter though, but that is not to say you can't do it if you want to.
As for pros/cons? I went on a rant here if you want to see my opinions: https://www.reef2reef.com/threads/filtration.825262/post-8878748

[EDIT]
Wait, you're the same person who asked the other day, didn't you already get responses to this question there?
Regarding your AquaClear question though, even just one can work depending on how much flow there'd be in the tank, and what sort of biomedia there is.
You don't always need a sump, but they are nice to have. It allows you to get equipment, like heaters, out of the display. You can also run a good skimmer in the sump, which is what I would do for a fowlr. Your display water level will also remain constant when running a sump, since the evap shows up in the sump. Sumps also give you more water volume.Yea I am, I’ve been doing more research about sumps but I’m seeing that they’re more so for reef tanks.

What you suggest for a skimmer? I need info on skimmers because they seem to do the same as a HOB, just with bubbles and the waste is visibleYou don't always need a sump, but they are nice to have.

In general, most people don't have 'filters' at all in saltwater tanks. Rock, sand, flow are the most important. Like I said, I would run a skimmer.
You'll get lots of opinions on what skimmers are best. It's kind of like lighting. I run an ASM G2 on my 125 gallon. Another good brand that isn't outrageously expensive is Reef Octopus.What you suggest for a skimmer?

All this valuable info! Thanks! Going to check out the internal onesYou'll get lots of opinions on what skimmers are best. It's kind of like lighting. I run an ASM G2 on my 125 gallon. Another good brand that isn't outrageously expensive is Reef Octopus.
Skimmers are very different than a hang-on-back filter. Skimmers remove waste from the water column before it breaks down, instead of a filter that traps waste and is only actually removed when you clean the thing. They also remove things that mechanical filters don't. They also aerate well beyond what a HOB would.

Look for something based on reviews and tank size. And you will want an internal one, not a hang on tank one.
Yeah as per @nereefpat, theoretically, you don't need a sump for any size tank. There are ways to have all the filtration you'd need in a tank.Yea I am, I’ve been doing more research about sumps but I’m seeing that they’re more so for reef tanks.

you don't need an overflow for surface skimming. there are stand alone surface skimmersMaybe somebody already mentioned it, or maybe not ..... the biggest benefit to a sump isn't the actual sump, is the surface skimming you get from the overflow. I think people generally fail to appreciate how beneficial that is.
Canisters aren't nitrate factories... if you load em right with the right media. In addition, in sumps your doing the same thing if you dont have a strict routine with your filter socks.Skimmer over cannister anyday. The skimmer is going to pull things the cannister can't, and the cannister produces nitrates vs remove them like the skimmer.
A cannister with functional UV is an interesting concept. Even if the cannister was empty and did nothing but provide UV it might be worth it. Basically it would be acting like a closed loop sump.
People swear by the sun sun canister filters. They have UV’s in themidk if any cannisters with UV built in are any good though, anyone ever use one for its UV before?
I’ve seen people use two of those canister filters with the UV’s because they’re so cheap...I believe a sump gives you more options now and in the future for a tank as large as the one you are considering. If you consider a DIY build, I think you can get out for a very reasonable cost. Also, If you go the FOWLR route and decide you don't want a big supply of live rock, different media options are available to process ammonia in the sump. Because your water parameters will not be as demanding as for a reef tank, you may find you can get by without a skimmer by using more media in the sump. Media is a lot cheaper than a skimmer. I use a sump for a 90 gallon fresh water tank as well as for my 125 reef tank.
I recommend you do a bit of research concerning the UV sterilize built into canisters. The ones I have seen are underpowered for larger tanks. I have external UV sterlizers plumbed into my return lines for both sumps and I've been pleased with how it has improved the clarity of the water. You should be able to find some wattage guidelines for different size tanks to help your analysis.
