Biggest models they make are the HW-5000 (fx5/6 style) and the HW-3000 ( electronic control...actually nice). A 404b will do your tank fine depending on what is in it. If you fill at least 2 trays with quality biomedia such as Matrix or Marine Pure it would be fine. Just don’t use cheap ceramic rings or bioballs etc...

I believe the 705B is biggest. 535 gallon per hour. Mine should be here in a few days. They make some larger pond filters that require a pump.
The US version is called Aquatop. Just make sure that you can move the largest canister when filled with media and water. The 303A model had decent weight to it (15-20lbs) when full of water and a decent amount of ceramic media in one tray.
Is the 304B that kno4te linked the same as the 404b? Now that I look on Amazon the 304B seems to have the exact same specs as the 404b I saw.
I also saw the Rena Filstar XP-Xl as an option. Are these any good? I looked them up and it seems as though there's a lot of people complaining that the tubes leak and the filter has a hard time starting properly. But I also saw some videos on the youtubez trying to debunk it?
I have heard some bad things about Rena filters but I’ve never used one myself.
Essentially the HW-3xx HW-4xx and HW-7xx ( the 02/03/04 is the size, the B means it has a built in UV) are the same in general operation. The 4 and 7 series are just later models.
Here is a good video explaining the difference between the 3 4 and 7 series...
And a video on the new 840gph HW-3000
I just ordered a 304B, I wasn't able to really find a solid seller for the 404. Are they harder to find or just less common?
4 series filters are are around but really not enough difference between 3 and 4 to matter. I’ve got 3, 4 and 7 series and they are pretty much identical in performance.
I like them because they hold a lot of media which is the important thing and the water flows with little if any bypass. Plus I don’t think they break anymore then say a Fluval does... mind you I still use Ehiem 2180’s on “important” tanks.
I suspect the new (ish) Oase canisters will claim Ehiems crown at the top end but they don’t make them big enough...yet.
