Hahaha I was actually doing that today during my water changes, except I was moving my lights around. I don't know why, but moving sand seems harder than moving lights for me. I'm adjusting my lights and it seems like my problem has been that I don't have enough blue to go along with all of the white the LEDs are letting off. I enhanced the blue on my current USAs and it seems a little bit better. I'm going to give it a couple days so the polys can settle down from the WC, because between the moving of the lights and decor I'm sure they've had their fair share of stress.
