My tank is dark or I would share a video I can in am if your still worried.. personally I think the only one that was getting hit to hard was the middle. I only say from one direction is bad cause I blasted a torch once and lost a head where it was taking the cross flow in one direction only. I prefer the wavy vibe. Just keep an eye if they are retraced or just looking blah go ahead and place them in a new spot.. I will say this my torches do not like getting moved around after established
