Ok well i have never used the seios before, i am setting up a 150 (60x24x25h), witha reef flo dart return pump.. i have a friend that offered to sell me two new seio m1500 and the controller for them for $120.. he never used them because his wife bought him 2 vortech mp40... i was wondering what everyones opinion is on the seios, are they decent, i know they arent the best, how is the controller? the only powerheads i have used in the past are koralias, they are ok..
