(I apologize if I'm hijacking the the thread, but...)
Could you share how you have/plan to do the light fixtures for your design? I've been in the planning stages of doing a similar setup with three individual fixtures on a 55 gallon, but I'm clueless when it comes to working with metal. It looks simple enough, but not sure what all goes into it.
Any details especially where you bought the parts and what you used would be appreciated!
