Thanks for the information. Your setup looks really nice. I've been trying to find ideas of how to hang my light since my ceilings are made of those little sandy dots that falls off when you touch or hit it I can't do any ceiling mounts.
My tank is on one of those 4 tier aluminum stand and right now I am just using the highest tier for the light. I just put my light above the 4th shelf and my tank on the 3rd shelf.
