Biomaster 350 filter for a 400L?

[boshk]

For a 400L tank, 150cm long (5ft), could I get away with a Biomaster 350 canister filter or would I need the 600?

Also for the length, would one canister be able to circulate the water or would I need 2 small canister on each end?

Stock wise...no real plans yet, no Discus, maybe Angelfish, low tech tank.

I’d go for the 600 or maybe even the 850 I have the 350 on my 100 ltr which gives me 9x turnover So think you’d need one of the bigger ones

Biomaster 350 might be enough though 600 is better unless you only have low bio load.

Bigger is always better as your filter will slow down after some time and to ensure that the filter media volume is enough to have enough beneficial bacteria to support the whole tank.

But for my personal preference(as its up to individual), I will get two Biomaster 250 for:
1)Backup purposes in case one breakdown.
2)Better filtrations as two are running at the same time. Put one on the left and one on the right side.
3)During maintenance, I can do one at a time without disturbing the beneficial bacteria too much.

I always err on the side of caution and would go for the larger filter as its always good to have this.

Mainly due to the capacity to hold more filter media and of course is more powerful which will give you more options stocking wise.

As for one or two canisters, well, its a personal choice imho, personally I've never had two large canister filters on any single tank.

The most I've had is one large external filter and one HoB mainly just for polishing the water as it just had sponge media and filter floss in it and was used to give a little extra circulation to avoid getting dead spots in the tank as I had lots of bogwood and plants in that tank at the time.

ive got a 450litre 5 ft tank and use 1 external Eheim that does 1000 LPH.

The intake is on one end of the tank and the out spray bar sits on the other. I also have 2 cheap powerheads ( one either end) to agitate the water a bit - since adding it the fish are a lot more active.

With the current livestock its ok but ill be investing in a second similar size external in a few weeks.

In the picture you can see the spray bar on the left and the powerheads prevent any dead spots.

I also agree with Charlie idea of having one canister and one HOB (Hang on filter).
One purpose of hang on filter is to remove the debris and its easier to clean and maintain HOB compare to canister filter.

Nevertheless, Oase Biomaster has a unique where its easy to clean the first compartment that filter the incoming water. Its easier to maintain Oase Biomaster compare to other brands of filters.

Using powerhead is also useful for large tank as James mentioned.
