Okay so I am going to be retro-fitting some T5's and I was wondering how I would do the reflecting part. I was going to put 8 bulbs on my 100 gallon and custom the canopy and the lighting, the reflection is the only thing I am not sure about. Also as for equipment all I need is the ballast's (would 2 do the trick), and the end caps. Was going to do the single, that way I can fit more bulbs. I am also going to be putting some moonlighting in that have a range of 3' from left to right and I am going to put 2 of them in evenly spaced. I will get a drawing when I can, tahnks for your help.
