Flow suggestions

[HouseofStark]

i have a 83gal Fiji cube and want to to get more back to front and down flow. I have the returns up top, but I have them near the surface for co2, and when I power down my tank for feeding need them to break the back siphon. I felt like a gyre would work/be perfect, but after reviews and realizing there’s not enough room between overflow and return (8”) I’m somewhat limited.

I currently have 2 mp40 on left and right tank….

Looking for suggestions, what would you do to rotate from back to front and down…. Two mp40s? I have 1/2” glass, so mp10s won’t work.

Thanks

What about moving the MP40s to either side of the overflow on the back?

A possibility, I do like the left to right flow now.. you think 4 would be over kill adding 2 to the back? I liked the thought for a sheet of water (gyre) vs the punch of a vortec
