Koralia for 110g: Mag 6 --> 8 - Which one?

I have a 110g X-Hi (48L x 18W x 30H) and I was curious what the max Koralia Magnum I could install? Currenly I have a "4" and it just is not enough flow. This will be my main 'circulation' pump.
The Mag 5 is not much higher than the '4' so that one is out, the 6 is just shy double of 4, which makes me wonder if I should get the mag 7. The 8 at 3250gph is almost 3x's my 4, which might just be overkill!
Currently the tank is LR with a few softies, tangs, & clown's.
I can only mount ONE of these in the tank due to the set-up, so I want to make sure I have enough flow. Obviously the 4 would be removed and the Mag would replace it.
Your thoughts are greatly appreciated! Thank you!

a very common misconception(one that I used to have myself) that people have is they want the water racing through the sump. If your not happy with your flow, get some powerheads instead of a larger return pump.
let the sump sit and stew a bit, thats the whole purpouse. i used to think increase increase increase...but now that Ive talked to more people with experiance, and read up on it myself.
And I agree with this concept.
Let the sump move slowly and stew in its own juices.
If you want high turnover, then get some more power heads. Korela 4's are a steal right now at $39 each.
I ahve a mag 18 and I keep it throttled down to about %70. and a dual drain sump design that lets me split the fallout into two seperate chambers, with the return in the middle. I have about 400gph into each side, with 800 returning up the middle.
For turnover, I beef up on the powerheads to compensate.
*edit*
wait a minute...you talking about power heads? I was kinda scratching my head..."Didnt know Korella made mag return pumps"
I just re-read that lol.
If your asking about power heads, go with a couple extra 4's and place them at different heights/angles. have the water bouncing back and forth off one another.
Think of throwing several stones in a pond in close proximity. the ripples bounce off each other and create more chaos than you would get if you threw in one large stone.
Its turnover your shooting for as well as flow. Having a water particle move in as many diverse directions is every bit as important as speed/force...if not more so.
Some corals like faster current. I suggest a tunze that you can direct to it...or putting the korelas closer to that specific region.
