3500g 40' tank

[BushFishRox]

a few of these should do the trick.

ha ha ha forget that BS make you own custom canisters out of some 55gal drums, I might take a look for you but I am lazy, but I have seen it done on some huge in-ground aquariums...

it was done with 3 drums filled with 3 different types of filter media then pumped back into he tank...

good idea on the drums...

well couldnt they just use one of the 400g tanks as a wet/dry?
and a butt-load of lava rock.

I think that would be the best bet

 

[BushFishRox]

that would be interesting to see an out door 400gal wet/dry ha ha

I saved that, but this is too funny to lock right now

iv never made a wet dry filter how whould i do that in the 400 gallon container. and would 1 of those be big enough?

should be, you will just need a few heavy duty overflows... and a big ass return pump

Is it a container or an aquarium?

I'm pretty sure you'd be okay with that.

5g bucket of bioballs is recommended for up to 300g.

that thing is 3500g.

So you'd need about 50 buckets of bioballs... i'm sure you could fit that in a 400g tank. 50x $30= 1500 for bioballs.

all you need is to make different compartments for your different filtration.

You need mechanical (filter floss) and biological (bio balls/ lava rock)

there are some great threads on DIY wet/drys.

its a container.

scrubies are cheaper than bio balls and a 24" in diamiter bio-tower, say... 10' tall...filled with them is all the bio filtration you'd ever need and at a fraction the cost of a 400 gallon sump.

 

[mcox3]

yeah but Bio Balls are soooo cool!
