Sorry to piggyback on this thread, but I was considering it for my 95 litre tank, but was thinking it would be too powerful.
So you have it on a 60 litre,
what would you say the flow is, more or less?
Does it create much current in your tank?
Is it noisy? Mine is buzzing quite loudly now and I wanted to get something witha bigger capacity anyway.

I have two of the better models, the 2000EFs, I run one as a supplement to my FX5 on the 5x2x2 and the other as a supplement to my Eheim 2078 on my Rio240. The real world turnover is truely shocking, if using spraybar modules the flow can be ~800lph, which is fine for all but things like male Betta in a 100l tank. Without spraybar modules (how I run both of mine), the flow increases to closer to the 1200lph ballpark.
The price is appealing (its why I bought them), but choose between the 1400 and 2000 models for a 50-250l tank, prefereably the latter and use all the 3 spraybar modules if you have fish stressed by current if needs be.
For flow and cannister volume for media, my FX5 stands out from my bunch of filters, its a shame they have shot up in price to ~£200 new but still worth it. My Eheim 2078 is not bad, what it lacks in raw power (~1150lph real turnover) is made up for in functions, even without the USB connector which opens up more functions via a PC. Two of the same model have capacity would be my choice for a 6x2x2.
I recently did a bit of window shopping at the APS site and I was intrigued by their pressure filter range, but I'm not sure how I would feel parting with almost £200 and risking a similar flow dropoff compared to the mrketing blurb.
