I've played around with my ph's too. i used to have them bowing both on the glass and off each other. Since I upgraded I have them both pointing at the rock and each other. I have mad circulation, I follow it sometimes when I feed to make sure theres no dead spots. I also have a fluval pointed at the front glass so I have that too and the skimmer. lol
