Need to up my flow. Wavemaker suggestions

[DEL 707]

I have 250l tank (200l display) and I need help getting the flow right.

These are slightly older pictures of my tank. I have a few corals in it now.

The return pump is a D-D Funktion 3500 lph. I have this set to 100% at a constant flow.
The powerhead is a D-D Funktion Wave 4000 lph. I have it set to 100% of a pulse function.

The problem is that the right side of the tank isn't getting enough flow.

I was looking at Jecod DMP/GMP. But the right side of the tank is close to a wall, so it wouldn't fit.
I need to outside part of the powerhead to be quite low profile.

I do have a Nero 3 from my old tank.
Would it be up for the job if I removed the Funktion wave and bought a 2nd nero to sync with it?
Or would I need to upgrade to Nero 5's?

Are they any other powerheads/wavemakers I should be looking at?

I would start by aiming your return nozzle towards the right side of your display. From the surface agitation in the picture, you seem to have good flow.

I have always found running pumps at 100% causes a lot of noise... Is your tank noisy?

I would consider adding a 2nd powerhead on the right side of the tank, if it can be syncd with the other powerhead, great. If not, not the end of the world.

With the addition of the 2nd powerhead you can almost certainly lower the return pump to 60-70%, if its noisy this will likely fix that.
