Hey, I have a 24" deep (40gal?) hex tank that I plan on building a brackish setup. I dont know too much about lighting but from browsing I figure a 4x24 t5HO would be the solution. Assuming that would work, the main question I am wondering is about the light positioning.
My tank top dimensions are 19 1/2 from side to side, and 22 1/2 from corner to corner.
This light setup http://www.catalinaaquarium.com/store/product_info.php?cPath=71_136&products_id=1411 has a width of 8 inches which I was thinking might be too thin and not allow sufficient light to certain parts on the tank.
My other option would be two 2x T5HO spaced out more. The two would look something like this.
