Is a Fluval FX6 overkill on a 120gallon tank?

[Gyarados]

The filter ran with roughly 3 cups worth of established bioballs for about 2 weeks before the fish were added. I know its a large volume of water for that much established media but the filter is filled to the brim with biomedia so it should grow eventually.

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

Oh I see well if you and your fish don't mind then screw it feed em 6 times lol

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.

900gph at the pump head. Filled with media it's around 500gph

I have an fx5 on my 120 does a great job.but I added a 850gph circulation pump at the opposite end of the tank of the intake. It helps move waste and uneaten food to the intake.does a good job.

My 120gal African tank has 2 fx5 and 2 aqua clear 110 and cf-500 uav from aquatop. The tanks is clean and clear all the time. Talk about over filtering. Every week I do a 25% water change and I clean one filter on a rotating schedule, ensuring that I always have good bacteria in the system.
