Just wanted to get some feedback as to peoples experiences and choices of filters. I am looking at getting a new filter (was running a fluval 304 on a 77g but realize I need a bigger/better filter) Here are the two i'm wondering about
Fluval 404 Or filstar XP3
what r your thoughts?

My thoughts of filtration...
Large (adaquate) quantity of Live Rock and SSB for Biological filtration (suface area for Bacteria)...High Flow , distributed through out the tank to keep deitrus suspended and removed from MT,promote gaseous exchange and maintain oxygen levels...a Large sump and LARGER Fuge with Macros for malnutrient removal through export (denitrification) and a Killer Skimmer to remove Mass quantities of DOCs (organics) prior to decomposition...
With a well balanced system, no other "filtration devices" (bioballs/biomedia) are necessary...Other than the ability to run Chemical Media (carbon or phosphate removers) from time to time, best done in a Fluidized bed (or converted canister) type system...
