Is a Fluval FX6 overkill on a 120gallon tank?

[ascarbo27]

Unfortunately a sump is a no go as I don't have the space hence the canister filter. I appreciate that too much filtration isn't a bad thing but it was the flow I was worried about. Is the flow adjustable or would the fish be able to handle that much output in that size tan
And also, could any FX6 owners out there give me an idea on what I should be using as media in one of these. Is what it comes with enough?
just get a dual return the piece that goes into the water, idk the proper name of it, that way the water isnt shooting in one direction. the flow one way will be cut in half if that makes sence

Make a spray bar to spread the flow out and will be perfect size. I have an Eheim 2262 which is almost double @ 900 GPH on a 125. I think it's perfect but plan on making spray bar longer.

I'm running an Fx6 on a 90g with a 5.5" midas and a 9" centro catfish. And though I'm feeding very heavy I still notice the water getting noticeably cloudy after a week without WC (usually do 2x75%/week). If you stock that 120 with reasonable size fish you may find yourself looking for a HOB on top of the Fx6.

Sounds like you don't have enough bio established especially doing 2x75% WC with only 2 fish..

i think the fx6 will be great with the 120 gallon, my sump is doing the same gph

on a 220

The amount of flow is really dictated by the kind of fish you keep, the FX6 is rated at about 900 gph, I run 1800 gph on a 125 without a problem.
If you keep rice paddy type bettas, or discus 900 gph would probably be a bit high.
My cichlids are not phased by the 1800 gph.
If you kept African Tiger fish, or any other counter current rheophilic fish 5000 gph would be walk in the park.

Input and Output flows on FX6 are adjustable. FX6 will be great for that tank.

I'm trying to grow the midas as quickly as possible so he gets fed 5ish times a day. I don't mind the water changes
