I have an Emperor 400 for a 75 gallon tank but I want to add a marineland c-360 or the one below that to it. DO you think I can get away with the one below that one with the HOB Emperor 400? I think its a c-260 or something.

Why would you want to go smaller? With the bigger one you could manage if your Emperor ever died and wouldn't have to clean the canister out as often.

Personally, I run a single FX5 on my 75 and it stays clean and well filtered. I also have 2 Rio 1700's running 8 USJ's though.

Go with the c-360 you will be disapointed if you go smaller. I run two AC 500/110's on mine with Fluval 405 and it is great. I get great water movement and the fish love it.
