MP10 Placement

[Goat]

I have a 40 breeder with a MP10 on the left side of the tank in front of rock about 1/3 down the wall and a Koralia Nano 565 on the right side behind the rocks about 1/3 down the wall. My question is the MP10 is incredibly stronger than the Koralia and the right side of my tank sand is clean and always moving, but the left side collects debris a lot more. Without purchasing another MP10 for the right side is there a better placement to get flow throughout? I run it on reef crest mode, but I'm trying lagoon for the night to see if a longer constant flow will help.
