Plumbing advice needed

[Picesduh]

Has anyone tried out the new DUO pump by Maxspect? I will be running a return on two ends of the tank too so I’m thinking of using this pump so I get equal flow to both rather than more on the closest one.

How does the height of these pipes look?

If this will work, I will do the other corner the same heights. With the return line going over the side.

Should I get the Vectra M1 or L1? Sounds like the M1 is big enough, but should I just up it to the L1 or way too excessive?

:) Thanks!

After reading reviews all day, I have shied away from Vectra pumps. Now I’m between a Sicce 9.0 or Varios 8. Any input on these?
