ebaer and sanjay: the spray bar is an added method of circualtion behind your LR. It's just a pump connected to a closed section of pvc with holes drilled in it. It helps keep "dead spots" from happening in the dark corners of your tank. I have one as well. It cost about 10 bucks, and I used a 40 gph PH. Sanjays system is different than mine, hence the extra pvc. The LR will hide the pvc (mostly) and will enhance the overall health of the tank. It's really a cool idea.
