350 Gallon tank filtration

Can you drill tank? It looks to be acrylic so its easier to drill then glass.
In tank overflow is much better. I would definitely go with sump since its so much easier to clean. Hide all your equipment, etc.

Google beananimal overflow. That's what I have on my 220g.
As far as return pump, I use a Laguna Waterworks 2000 GPH Max-Flo. Although larger, it is very energy efficient, only use 80w.

On something that big you might want to go with 2 FX6s or 5s.

What are you going to put in the tank.

If I knew anything about sumps im sure I would recommend that route but have never tried them.

You can change the output tube to a clear tube and use a reducer for the inline hydor that's what I did.

Drilling the tank is out of question.
Did reducing the tube on Fx6 reduce flow a lot ? Can you actually use clear tubes on both intake and outflow ?

The tank will have Arowanas in it i believe, sandy bottom and driftwood.

In my opinion avoid the fx series filters, they are significantly reduced in biological filtration when compared to an E series eheim. I used both fx and standard fluval canisters initially on several large setups (108 - 265 gallon). To out in flatly the eheim 2080 does more work biologically than an fx5 or two 405s.

You must use the two intakes on the 2080 though. It results in some unsettling in some disturbing noises if you don't .

Hi Eviltwist,

It did reduce the flow a bit although can't really say how much, I also started to use a in line reactor at the same time, probably isn't that substantial.

Yes you can use clear tubing on both, the problem would be finding a new intake grid for the tubing.

There is an arcticle out there that compares fx5 to eheim 2080 and the biological is better on the Eheim, I believe the mechanical is better on the Fluval. I am a big time Eheim fan but my fx5 works great on my 75, it is a nightmare to clean the sponges though. I clean them every 2 1/2 months, it takes me about 30 or more minutes just to get the gunk out of them with a garden hose. I have been thinking about getting extra sponges so I could just replace them each time and soak the dirty ones for as long as I wanted.

You might want to consider a FX6 and a 2262 that might be a winning combo.

A sump would be pretty much the only way to go here.

You might consider more flow in addition to the return pump, eg, a Vortech or similar.

The fish will do better with the sump.

That was the initial idea to do the sump tho neither me or him ever built a sump.
I don't know which overflow to use and if only one would work or we have to do two.
We will need some driftwood too so we will visit you in the coming days to pick something up :red_mouth Will let you know in advance.

Why can't it be drilled? That is definitely the best way to go. I have planted tanks and reef tanks. Drilled. Not drilled. I've used CPR overflows. Diy overflows. Hob filters. Canister filters.

For that size tank, drilled with a sump is the only way to go. IMHO

All the equipment can be hidden. The water level is always the same in the display tank and the water stays cleaner.

And a bean overflow setup is super quiet!
Siphon overflows are not.
They are very noisy.

Def! Go for sump, that big you'll end up needing 2 filters or more to keep up. Use a sump and keep good,flow in the tank. Use good powerheads. Sump will hide everything,and allow a fully custom filter system capable of filtration thst size.

Stop by and you can see both.
I think the largest CPR will do fine.
Add a Vortech or similar and that should pretty much take care of you.

I have a client's 350, 96x28x28 with a large sump similar.

So I have a pretty good idea of how things go.

None of my tanks at home are drilled.

You can convert CPR to bean animal style.
They can be very quiet.
