fluval 404 vs ?

[freshmike]

I want to get bigger filters for my 180....I am currently running 2 fluval 404's and I want a higher gph.....with at least the same quality of filtering capabilities.
Any suggestions?

I want at least 600 gph per filter......and must be a canister.....

If you want 600 gph I think your only option is the EHEIM pro series - you're talking big bucks. Here is a link to their web site listing all their pro filters and the specs on each.
