I am planning out a canopy for my 180g. Currently I have a acrylic light rack that holds 3x Radion G3 Pros about 8 inches off the water. I'm building the canopy to raise the lights a little higher and add some T5's to help with shading/colors. I am thinking about making the canopy 13 inches tall and thinking about 2 rows of T5 in front of the radions and 2 rows behind using a four of the 2x39w retro kits. Will this be enough T5 and do you think the height is at a good level?
