whats the largest filter in their range??



also, im after a filter with a whole heap of output power to get quite a bit of water flow in a 6x3x2 , what would you guys recommend ?

[Bowdy]

Pretty sure 2260 is the largest one they make but pro3 2080 is also a great that's rated to 1500L tank I think

Eheim Classic 2260 ( 1500XL )
•Aquarium Size: 1500 litres
•Filter Volume: 23 litres
•Pump Output: 2400 lph

Id go either 2x2260 or 2x2080

Eheim are renowned for over exaggerating their tank size suggestions Eg. Would you really use an Eheim 2213 on a 250L tank? Possibly, but it would be under-filtered that's for sure! (IMO).

On my 7x2x2.5' (~950L - which without calculating, would be of a similar volume to your 6x3x2') malawi display I use an Eheim 2080, Fluval FX5 and Otto 2000lph internal and only just see it as sufficient.

Of course this is an expensive route, perhaps a sump would be cheaper?

2x2260's bit over the top I'm all for twice what a filter rating is , that's what I aim for but thoes things are huge mate have you seem one ? What are you going to put it the tank ?

[Mr_docfish]

I have a 7'x30"x32" - 1300L with only a 2180 on it. It is only a planted tank, so it is an over kill.... if I had tank busters, I would have used a 2260 with a prefilter (easier to clean)... if ever I intended to remove the plants and go big fish, I would keep the 2180 since I already have it, and add a larger internal filter to cope with the load of waste and keep the water and dirt moving.

Flow rate and canister volume are two big issues to consider.... high flow rate and small canister volume just does not cut it in my book unless all you are doing is the same as an internal filter - move water and catch heaps of dirt... but if you wanted to convert ammonia and nitrite efficiently, then moderate flow rates and larger canister volumes are more the go. With canister volume, it is also advantageous to have media with a large surface area... but it is often a trade off with getting the pore size right and not letting it clog up quickly.... this again depends on the sorts of fish you intend to keep.

On the topic of Eheims, at Aquotix, we have a 8'x30"x30" tank with tank busters in it and a 2260 with a prefilter..... works a treat.

Seen them plenty of times, but they are well overpriced IMO (A bucket with a pump attached, and you have to buy taps additionally? Crazy Eheim!) . It all comes down to personal preference really. A good friend of mine is using 2x2260's on a 4.5x2x2' planted tank...

The Aquotix tank also has a denitrator which presumably helps with the nitrate issue in a TB tank.

Well the second 2260 was a huge waste of money really. Buy if you have bulk money why not I guess.

I'm hoping to replace my bunky back up canister with a big Eheim classic once the back up filter dies. I've seen one at a mates place just down the road from me. They're big, powerful, and easy for parts (being Eheim) and maintenance. Don't think i'd get another fx5, I'm not a fan of the hosing supplied

[Bowdy]

I have a 2080 on my display Jason and there awesome. It has a pre filter that traps the crap before it goes into the media. I highly rate them. Come over for a look and il take it apart and give you a look it's due for a clean. Cheers.

[acerimmer]

loving the 2217's.. been using 2 of them along with an fx5 on my 6x2x2.

[Westie]

3 canister filters on 1 tank? go rimmer!

it will be for the malawi display, about 20 or so really nice and getting large malawi`s



thinkin one of the 2260`s and a big internal, if thats not enough, i have an aqua one 800ltr aswell i can use on it.

[Bowdy]

Only 20 fish Boof that things going to look empty look forward to seeing it mate.

[Evil_Boof]

its everything out of the 5x1.5x1.5.. once i have more room, ill get more fish...

bowdy.. i brought 3 of those 500lt caged tubs the other day, 40 each

[lawdog]

I run a 2250 with a 5000lt /hr ish pump with it that is running my 7'tank. Speaking of which it is being replaced. I use 1"inlets and and adapter to a 1"outlet and then to my uv etc.
If you want a large capacity filter the buckets with suitable aftermarket pumps are great. I may do a very good deal on mine if you are in the market.

Thank Matt

fx5 is great, great for value, heaps of volume, heaps of turn over. 429$ you cant go wrong. mines been pumping non stop for 18 months never missed a beat. its along side a aqua one 2400 on my 6x2x2.5, 55 very large cichlids (15-25cm) and my tank has gone 5 weeks without a water change before and they were still breeding in there.

Your nitrates must have been really high after those 5 weeks - so whilst your fish were still alive, the prolonged exposure to high levels of nitrates may have caused some damage you can't easily spot.

The first and foremost function of any filtration system is go get rid of undesirable chemicals in the water (ammonia and nitrite most specifically), as higher levels of those chemicals are lethal to fish. After that it is up to the waterchanges to get rid of the other, not so lethal but still undesirable chemicals.

Breeding should also not be seen as a sign of good water quality - in fact some fish will only start breeding if you don't change the water for a longer time and they get stressed. It's easy to connect the two because it seems logical - but as I've learned it should not be seen as a blanket rule. It may apply for some species who will only start spawning if the water parameters are spot on - but I think those are in the minority.

I have witnessed the "stressed fish will start breeding" theory first hand, and it does make sense if you think about it.

Sorry I've gone a bit off topic

Eheim 2080 is an awesome filter. User friendly, reliable.

[Evil_Boof]

would 2 filters be best, or one big one and a big internal? im leaning towards one cannister each side of the tank.

[Westie]

i've gone for 2 canisters as i find it easy enough to clean, and i dont want to muck around with taking the hood off too often.
internal should be sweet too, as it will put oxygen in the tank if you have a powerhead filter
