Hey man, great build! I am currently building a 400 gallon, viewable from two rooms in my home. About to hang the lights. I got 4 of the large Orphek fixtures. What is that track you are using to hang your lights from? I've been trying to figure out how I want to hang these. As they will be in a cabinet I'd like to try and find a way to be able to pull them up for maintenance when I need to get in the cabinet over the top.
