Powerhead Placement
 

My tank is 2x4x20" deep. I have two Tunze 6095 PH's, one in each back corner angled toward the middle of the tank. I'm not sure I am getting good flow even though they are on full power. What is your PH placement? Maybe put them on the ends facing each other would be better. Looking for suggestions before I start moving things around.

Try them on pulse first since they are 6095s and have their own controller. Set main power to 90% and pulse power to say 30%. If you put one pulse time to roughly 5 seconds and the other pulse time to roughly 7 seconds then sometimes they will both be on, sometimes both off, or switching back and forth, just stagger them a second or two. You can also try placing one closer to the top of the tank and the other below it or different things like that. Just suggestions that's all.

I many times try for max power, as long as my sand isn't blown around nor any corals are directly in the line of flow.
