I have an Oase on my 20 gallon Nano. I highly recommend one. It's at least as quiet as any Eheim I've ever owned. Personally, I'd go minimum 350 (or bigger) if your cabinet can accommodate it. Canister filter flows are rated without media, so cut the flow rate in half with whatever they advertise.

Just a head's up: any minute now the "I've never ran a canister filter, but I am an expert on canister filters" police are going to chime in despite your request to the contrary. These people can't help themselves.

Second, someone is also going to suggest filling the trays with live rock. My suggestion, don't. You want maximum surface area that tumbles in the trays. Oase already did this for you with their proprietary media that comes with every canister filter they sell.

I don't know flow rate . I use a Fluval 307 on my 45 only. I also use the same on my 100 but with a sump. I know some people use 2 of the same no sump for their 100
 
The guy I mentioned just fills one with Rock only . Interesting
I ran an Eheim 2213 on a 29 gallon reef for 5 years, tried rock rubble but it severely cuts the flow rate down. You really just need sponge/floss filter in a canister, your rocks are your biological media

I am unaware. The Fluval I mentioned has included sponge filters. As far as reduced flow I wish the aforementioned guy would chime in , In my case having adequate flow from my sump . I would not be concerned about flow if I am getting excellent contact time with the rock that converts the unwanted chemicals and nutrients. I even would consider sand . Just a thought

Sand is even worse. The point of the filter is to take out particulate, your rocks provide all the area beneficial bacteria need.

The Fluval People have Activated Charcoal Ammonia media. Water clarifying Media Phosphate pads Nitrate And Nitrate pads as well as other bagged or Bulk Media . I would consider that a refugium if you will.

The fluval people have all kinds of disposable stuff you can buy. When people have an interest in your wallet, take their advice with a grain of salt 😉
 
I have a Biomaster 850 Thermal and Fluval 307 on my 75g planted. Having the heater in the Oase is nice, though even with more coarse foam in the pre filter I have to clean it out a ton.

I also have a Fluval 307 on a tiny 5g nano. Not sure I will ever have to clean it. I check from time to time but the bioload is so light there's never any buildup.

My advice is to get one with more advertised flow than you need. Usually the published flow rates are is super ideal conditions and are hard to achieve in practice.
 
I've run canister filters in the past, on various marine tanks, and the larger Fluval filters do the job great. The FX4 was what I ran on my last 75-gallon tank.

I see they have a FX6 now and I'd probably go with that if it was my choice. May want to check footprint though and make sure it fits your space. The FX series are not small pieces of gear. They are double the size of the 307/407 filters.

Thank you for your response. Yes I am leaning towards an oase thermo. I also see people saying they toss rocks in there. I know better to do that after watching a few people on YouTube with them and their reef tanks.

I had to add that disclaimer because I had notice on social media people just want to comment and not even read what I asked lol. I remember I asked about a light and someone was like “get soft coral they are nice” it had nothing to do with my question about lighting 😂

Hi Grog ,

Are the ducal canister filters Loud ?
 
Thank you guys for the replies very informative. I have no me question are oase the only brand with heaters ? I was watching BRSTv and saw the new SICCE mega filtra canister filter I was looking into those but my main concern is being quiet.
