Howdy,
Sorry for the delay in response ... been busy. Here we go:

Hey HarleyK, a quick question for you. You state that you want your bio to do a bit of mech filtration. This might be ok (or not?) when using substrat pro, but would the **** not get stuck in the micro pores of the substrat pro; reducing its effectiveness/BB capacity? The substrat pro might have been designed so this would not happen though...?
I have both substrat pro and sechem matrix in my 2217 and place one white pad on the very bottom to prevent just that from occuring.
Any thoughts much appreciated!
I think the white pad (fine), if it's the first layer, will clog up too easily, causing you to open the filter prematurely, disturbing biofiltration. Mech filtration should go from coarse to fine, i.e. EhfiMech, maybe EhfiFix, blue pad, then bio, and white pad on top. I do not believe that biowaste can quantitatively clog up your biomedia if you have such progressive mech filtration in place. I see biomedia as one step near the end of mech filtration. Think about it: it has to trap particles in order to biodegrade them. Not everything in feces is watersoluble. I want my biomedia to trap stuff, so that the last step (white pad or filter floss) does not clog up too early. That layer is just to polish the water, nothing else. But again, if too much crap gets thru all media and hits this white pad, the last line of defense before water enters your tank again, then this requires you to open the canister to exchange it. I hate that. I love my one-year service intervl

May I ask what the backwashing you referred to with the clear tubing is? New to the whole canister filter scene....

I currently have an overstocked 175g Bowfront filtered by 1 2262 and 1 2028. Looking to replace the 2028 with either a 2260 or 2262.
The tank holds;
1 rtg arowana 22"
6 6" king kong parrots
1 thinbar tiger dat 8"
and the filter cloggers, 7 royal plecos, 6-11"
The only reason I'm considering the 2260 is for the lower gph= more time for bio-filtration (I think?) and concerned a 2nd 900gph may be too strong a current for the fish.
The 2262 is 1 yr old, replaced a 10 yr old 2260 which is now with my 144g.
A 2250 9 yr old and filtering my 90g.
The 2028 pro II is 6 yr old.
Never a problem with the classics, not 1 !
2028 still on the original head gasket, has never leaked, although has started rattling after cleanings or power outages. The impellar and axel look like new, and the impellar hole feels smooth, noise stops in around a hour. Idk if this counts as a problem, it's still running strong.
Bought the 2262 after reading Harley Ks reviews, than you Harley.
This is easy, because I made that mistake: Go with the lower flow, i.e. 2260. If you go with the 2262, you will have to modify your filter outlet to reduce flow velocity, not only for fish, but you would be running the risk to get brown beard algae. read -->
HERE <-- Unless you have tons of floaties and need the added mech effect of high gph, I'd go with 2260

One of the best. The Fx5 is the other.
[...] they both have equal build quality
*
cough cough* Just for fun, search this forum for equipment failures with FX5. And check how long they've been on the market for. Then read in the posts in this thread here (or others threads) how 20+ year old Eheims are still in operation. I think Hagen/Fluval still has some homework to do. Let's talk about build quality comparison again in a couple of decades when we can count the surviving filters
