Flow in a 200g

[Grasshopper04]

I have a 200g display (60" long, 30" wide, 22" deep). I'm using two MP40s currently. They are mounted on opposing ends, 1/3 down from top, 1/3 away from front and back, offset. I have them programmed to Reef Crest at 90% max flow rate, one slaved to the other.

I feel like I'm not getting as much flow as I really need, particularly in the middle of the tank. Should I consider adding another one, mounted on the back wall? I don't want to use any powerheads which require cords to go over the top.

I would maybe mount the two you have on the back

I've got a 180 4'x3'x2' and run 3 mp40s, 2 tunze, 1 nero5, and my return pump is extremely strong. More the better IMO, can always turn them down and have more varied movement

I ordered another MP40 to put on the back wall. Seeing red algae accumulate on the ends of some SPS I have positioned in the general region where I was considering adding the MP40 sold me.

Any suggestion on how to get that red algae off without damaging the coral?

Also the tank is 72" long (6') not 60", not sure if that makes a difference in this conversation.

A video of the flow might help.
