Hello all,

I have a 30g tank with live rock and sand substrate with 3 chromis. I have 1 powerhead in now with a 160gph output. I have heard that I should get 2 in the tank and not have a circular flow but have them aimed at the front of the tank. Anyone have suggestions on placement? please let me know.
 
You can place them on the back wall of the tank, aiming them toward the center front of the tank. You can also have one on each side (right panel, left panel) aiming at each other. Both ways would work fine.
 
My rock slopes up towards the back and top which is common. I have a Koralia 1 pushing water behind the rock in the back and it prevents some detritus from settling back there.
