softies tank - how much flow do I need?

[ShrimpDemolisher]

My tank is 75gal with some softies (mushrooms, zoas, kenya, xenia) and in the future will be some birdsnest sps and lps. I currently have 2 Koralia 1150, so total is 2300gph = 30x. Is it good enough?. The powerheads are so dang huge though, to the point they look like eyesore in my tank.

10-20x is more than enough, but never all from one source, have at least 2

I like to have three. One for low backside of rocks and two for other areas.

Can I put two on the sides: right one close the front and left one close to the back, which creates a circulation flow?
