Filtration for an 180 Gallon Tank

I think i've decided to go with the 4 AC's and 1 fluval fx5.

Will fluval fx5 suffice to go along with the 4 HOBs or should I think about a second fx5?
 
1 FX5 and your other filters will more then enough just order it and hook it up and enjoy your tank.
 
Yeah thats what I am gonna do..I will go with the 4 AquaClears and the single Fluval fx5 and if within the first few months I see that the filtration isn't good enough, i'll invest in the second Fluval fx5.

If not i'll just stay with the same group.
