Red sea reefer 170 powerhead placement

[Rabbmacc]

Hi all I'm looking for some advice. Finding the right flow and placement of my powerheads is my problem so I was wondering if anyone has a red sea reefer 170 where do you place them and what setting thank you

I ran 2 MP10s on the back wall on each side of the overflow before my 170 had a seam fail. I ran them on reefcrest but can't remember what %. I don't really watch numbers much and never calculate flow. I just look at coral movement and how food gets blown around the tank.


This was at it's peak.

I also had mp10’s on the back wall, reefcrest 30%, but it depends on your rock work and corals you have. They have great flow patterns.
