Powerheads for 4ft 75 gallon: Do I need more firepower?

[Nooooooooob1]

Moving from a 40b up to a 75 gallon. I've been successful with SPS in my 40 with two Jebao OW-25's running at only like 25-40%.

Anyone think I'll need more power than that for SPS in the 75? If so, I was thinking about putting the two OW-25's on one side and a Gyre XF330 on the other, facing each other.

Thoughts?

Also, do you guys use another, weaker powerhead on the back side facing forwards for some extra random turbulence?

I used two mp10’s and they worked well. The gyre would be good.
