Moments before spontaneously combusting lurker was heard opining:

eheim 1250 317 gph, i've heard eheims are very good but that they are
better for circulation and not for preasurized filters due to it
being designed for circulation..

also this pump can be ran externally or submerged. not sure if this
matters.
=================
That would depend on what you wanted to use it for. I use all mine
submerged.
