I am in the process of setting up a 10 foot long tank 300 acrylic gallon tank. For lighting I am going to use two four foot T5 fixtures and then supplement LEDs. I am trying to avoid hanging the lights, so what I want to do is set the lights on top of the tank. The problem is that I don't want to have the mounting legs putting weight on the cutouts of the bracing. So does anyone know of any kind adjustable mounting kit that would go across the width of the tank that I could use to set the lights on? I was thinking of fabricating something out of acrylic square rod but I wanted to see if there are any products available that would allow me to accomplish this easier.
