really i hav a mag 7 and a rio pump rated 4 675 gph so abt 1375gph total on my 72 bow for return and its still not enough for my tank even with the additional power heads 2 k nanos, 1 k1, 1 mj1200 and one of those new square 500gph ph its still not enough
personally for what she wants to put in there i think reeflo dart is perfect and low elec cost 145w i think just my opinion
