400 gallon canisters?

[Sully 400 gallons]

I want to start I'm new here I have had tanks in the past this being the biggest I ever have had. I ordered a 420 gallon tank platform is 8 feet long 32 in tall 28 in deep stock I want like 4 Orinoco peacock bass 1 black Arawana and 1 red tip catfish. I don't want any holes in the tank so I was thinking three fx6 would that be able to keep up filtering my water thanks for the information

I would think that will be plenty , if you need more circulation , power heads should cover that

Yah, that should work
if you dont want to drill your tank, you can make a HOB overflow. They arent as efficient as a drilled overflow but they work if you want a sump.
