The rule of thumb from what I have been told is X 10 what whatever Koralia will push 400 GPM.
I have a 75 gal and I put in 2 koralia 3's. I figured it cant hurt and I am VERY happy

based on the depth of your tank, I would recommend the 2's. I would guess that the 3's would blow your sand all over the place (assuming that you are going to have or do have sand). I would go with only two, one on each end. You may find then that you have dead spots especially behind the rockwork in the middle, and you may want to add a 1 there. JMO

I have a 48 tall, it is 36 inches long. I have a mj1200, hk3 and a small ph in center. I can`t leave hk3 on constant because the flow is insane, in a tank that size. I use it once a day to change things up for coral and clean debris of rock and sand bed, but i would never leave it constant.

I just put in a #3 and #4 into my new 75g and so far nothing is flying around. I have them blowing on opposites sides of the rockwork in about 45 degree angle.
If I could justify spending a load of money on PH's, I'd go with Tunze 6101's.

I'm glad to hear you mention the #4 with a 75g. I just picked up a #4 for my 75 and was afraid it might be to much!

Depends what your planning on keeping....Different things require different flow, and a lot depends on your tank layout and rock structure as well....All these will dictate flow needs.....
