Thanks for the replies guys.
I've used both the FX6 and the 2080, and I suggest that if you swapped to the FX6 you would be very disappointed!
How have you got the Eheims set up? What media are you running, and are you using the Eheim white and blue filter pads?
I have all the default media installed with my Eheims including the white and blue pads. Regardless of how often I change the white pad, it doesn't make a difference. Can confirm great flow from both.
If converting to a sump is an option you can and are willing to take, then go for it. Cannot compare a properly set up sump to a canister filter, they are worlds apart.
I wish I had gone down this route to begin with. I purchased a second 2080 to handle the bio load quite a few months ago and could have invested in a DIY sump. Might try setup a smaller tank with a small sump to get the hang of it.
I have combined the two intakes into one 25mm pipe intake. Works well, I need to clean the top coarse filter pad once a month (medium stocked 8x3x3).
Do you mind sharing your details or parts on how you did this? I had a quick look down at a Total Eden and couldn't find anything promising.
Adding a powerhead style filter that specializes in mechanical filtration beside the canister intake would also improve ability to capture particles.
Do you have any quality power heads and sponge setups you would recommend? I have previously had some Ottos and find they can be a bit noisy after a while.
Cheers,
