When it comes to large capacities, usually that includes lower restriction. The 2262 cross section surface area is larger which could reduce restriction. So this would not be a reason why the 2262 has a lower flow rate. I could be that the filter is designed for the lower flow pumps and putting the 2262 pump on might just be more about marketing instead of function.
Go ahead and buy a 1200 gph pump and put it on the 2250 or 2260. I bet you won't get more than 500 gph. The filter canister will be the restriction at that point.
I don't need to do this on the Fx5. The more flow you add to a canister filter, the faster it will clog up. If you were ACTUALLY able to double the flow of the 2250/2260 you would clog up twice as fast.
Why do they need another one?
This goes true for all canister filter.
Ehiems do have all that. BTW, my Fx5 has been running for years. Usually goes about 6 months before cleaning. Reliable, low maintenance and good.
This is a good tread and i like to respond to your quote.
Firts, i had swap pumps on my eheim 2250 canister, this unit holds 12 litres of media and comes with a 1250 pump rated a 320gph, the change was a 1260 eheim pump rated over 600 gallon, twice the flow and i tell you, i did not loose as much flow as you said, instead i gain considerable amount, but i have to be honest and say that it clog more frequently; but its not a every month service, the 2250 its pack with eheim mech and bio pro.
Now if i want to go 1200gph on my 2262 i will have to repack this canister, give away one of the best biomedia eheim pro, and get 10 or 5 PPi sponges so i cut get some crazy flow, do i want to do that?.. no, of course not, why would i mess with a perfectly well done well balance canister.
I had done some experiments with ocean clear nuclear canister, you can go up to 1700 gph on them. I have to ocean clear they are connected to one pump, I try first a panworld 150px this pump its a 1200 gph at 28 ft of pressure it was so much flow that i had to take the pump down, not to mention i was hard to cultivate bacteria,I replaced it with a 100px at 800gph at 21 ft of pressure, this is a 220 gallon tank, over stock. When usign this type of filtraion i like to run two units in line, the first a 25 microm cartrige fallow by the second full of eheim biomedia. Using the firt pump (150px) did not loose any flow and i did not clog to the point of getting 500 gph, so what i want to say its not about some crazy flow, its about balance and thats what you get with eheim canisters, well balance well made and a very, very long time of service with minimum cost, eheim 2213 almost 20 years, 2260 15 years.
Now your fx5 the same one i had, to me it just a big bucket fill with sponges, the amount of media you can use its no match, my 2028 takes more media then the fx5, and i did the comparison filling the 2028 and dump it on the fx5, i had some extra media, also you said you service your fx5 every 6 months, i don't know what you have in it, but on mine i had eheim mech in one tray and the other two trays eheim bio with one layer of a pad, it will clog so quick that you have to do maintance so often that i got sick of doing that , i don't know what it is, if the surface area area its too small to use polishing pads, or it just a bad design.
If you don't believe what I'm saying take a poll how often you service the fx5, and see whats the answer, and what up with the micro bubles thing.
Finally, i have to say fluval don't have to make another big canister.. Why?they can make a good one, so thats why probably they went with the g6, instead of maybe fixing the flaws with the fx5. The g6 has way less flow, and i read problems with cloging with the init as well.
So in few words as much you want to tell me fx5 its equal or superior to the 2262, I say again no way jose, media capacity, different medias you can use, flow and mantaining the flow for a long period of time, well reserch done witth the eheims.
