Ok,im trying to decide on which pump to go with. A sicce 4.0 or sicce 5.0 for my 180 dual overflow aqueon tank. At 5ft of head Im looking at about 750-800 gph with the 4.0 and about 1000 gph with the 5.0. Would the 4.0 be better to allow slower movement over the biological media in the dual trickle tower sump?
