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 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?

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.

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

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.

internal should be sweet too, as it will put oxygen in the tank if you have a powerhead filter
