if that blueline is 1,750gph like i think it is(much more, the overflows wont handle it) that in my opinion is defenitally not a lot of flow... its adequite for a tank but i wouldnt be investing a ton of money in sps without investing money in some more flow... in my tank which is a 125, i had a 1,300gph pump running two penductors(make 5x the flow... they say) sps were doin ok with not a ton of PE. when i added my two MJ mods, everything really improved a lot. i had to put crushed coral down because there was so much flow... but its good for the corals.. also, its kinda cool because in the center of my tank, it makes a little water tornao every 20 seconds and puts some big bubbles in the water which makes it look like real waves...
