Filtration question

[Dechstang]

I've got a bare bottom tank running the tank dimensions are 60" Long x 18" Wide x 24" Tall. I currently have three HOBs running on the back two are Aqueon Quiet flow 55/75's and the third is a Aquaclear 70. My question is this enough filtration for this size of a tank, I'm interested in monster freshwater fish so if anyone can chime in on this it would be greatly appreciated.

I don't know anything about the Quiet Flows but my guess would be that it's not nearly enough.

I have quite a few CA/SA cichlids in a 150g and run two FX6 and it could honestly use more... Like two AC110

Yeah, if you're interested in really large fish (and their large bioload), you'll need more filtration.
